4). Conversely, when infected macrophages were cultured in the presence of NKG2D siRNA-transfected Vγ9Vδ2 T cells, a significant increase of CFUs is observed and corresponds to a decrease of the anti-infectious activity of the Vγ9Vδ2 T cells (Fig. 4, black bars). This effect is not observed with control siRNA-transfected Vγ9Vδ2 T cells (Fig. 4, black bars). However, although the impairment of Vγ9Vδ2 T-cell functions is significant, it is weak. This could be explained by the fact that NKG2D expression is not completely silenced but only decreased. MAPK Inhibitor Library price Thus, the remaining NKG2D molecules expressed at the Vγ9Vδ2 T-cell membrane could interact with

their ligands and continue to trigger biological activity. To eliminate this possibility, we impaired NKG2D recruitment by blocking its interaction with its ligands by using a blocking Ab specific to NKG2D (M585) (Fig. 4, grey bars). We demonstrated earlier GS-1101 molecular weight that this M585 mAb blocks signaling

transduction and inhibits biological responses induced through NKG2D. In the presence of M585 mAb, the effects of Vγ9Vδ2 T cells are partially inhibited, and comparable to those observed with the modulation of NKG2D receptor expression after NKG2D siRNA transfection. M585 mAb has no effect on the multiplication of bacteria when infected macrophages are cultured alone (Fig. 4). In order to know if we can totally abolish NKG2D impact on Vγ9Vδ2 T-cell anti-infectious activity, we combined

the M585 mAb treatment with NKG2D siRNA transfection. The blocking of NKG2D siRNA-transfected Vγ9Vδ2 T cells with M585 mAb does not modify the inhibition of Vγ9Vδ2 T-cell effects. Taken together, these results suggest that NKG2D is partially involved in the anti-infectious response of Vγ9Vδ2 T cells against Brucella infection but other mechanisms must also intervene. To further determine signaling pathways implied in anti-bacterial Amine dehydrogenase activity triggered through NKG2D recruitment, we decided to identify adaptor proteins interacting with NKG2D in Vγ9Vδ2 T cells. We performed the immunoprecipitation of NKG2D and analyzed by Western blot the presence of DAP10 or DAP12, two adaptors proteins known to interact with NKG2D. In Supporting Information data 5 panel A, we observed that only DAP10 coprecipitates with NKG2D in human Vγ9Vδ2 T cells. To evaluate the role of DAP10 in the anti-infectious activity of Vγ9Vδ2 T cells, we have transiently transfected Vγ9Vδ2 T cells with a pool of four siRNA sequences specific for DAP10 using the same protocols as for NKG2D and observed a down-modulation similar to those of NKG2D. Then, we analyzed the impact of DAP10 down-modulation on bacteria development. When infected macrophages were cultured in the presence of DAP10 siRNA-transfected Vγ9Vδ2 T cells, we observed a significant increase of CFU of the same level of that observed with siNKG2D-transfected Vγ9Vδ2 T cells (Supporting Information data 5, panel B).

Spots representing single Ab-secreting cells were developed with the substrate (a buffered solution containing 4 mg of 4-chloro-1-naphthol, Sigma–Aldrich). The spots were counted with the aid of a dissecting microscope. Flow cytometry.  Single cell suspensions (1 × 106/sample) of pooled NALT and NP from seven untreated and immunized mice were stained with fluorochrome-labelled mAbs as described previously [8]. The surface phenotype of cells was analysed using anti-mouse mAb (Becton Dickinson Technologies, Gaithersburg, MD, USA) purchased from PharMingen (San Diego, CA, USA). The mAbs used in this study

included anti-CD45R/B220+ phycoerythrin (PE) (RA3-6B2), anti-CD3+ fluorescein isothiocyanate (FITC) (molecular complex 17A2), anti-CD3+ peridinin chlorophyll protein (PerCP) (CD3e chain) C646 in vivo (145-2C11), anti-CD4+ FITC (L3T4) (6K1.5) and anti-CD8a+ PE (Ly-2) (53–6.7).

For analysis of activation marker expression, the mAb used were anti-CD25 (FITC) (IL-2Ra chain, p55) (7D4), anti-CD25 (PE) (IL-2Ra chain, p55) (7D4), anti-CD69 (FITC) (very early activation antigen) (H1.2F3) and anti-CD69 (PE) (H1.2F3). To perform flow cytometric analyses, relative fluorescence intensities were measured using a FACSCalibur cytometer (Becton Dickinson, San Jose, CA, USA) and BD cell quest Pro v.5.1.1 software (Becton Dickinson). For each phenotypic characteristic data were collected for 20,000 events. Lymphocyte phenotypes were determined by two or three colours immunofluorescence. The percentage of cells labelled with each mAb was calculated in comparison with cells Wnt antagonist stained with isotype control antibody. B and T-cells were analysed within

a lymphocyte gate defined by forward and side light IMP dehydrogenase scatter. Background staining was controlled by labelled isotype controls (Pharmingen) and never exceeded 1.0% of cells. The results represent the percentage of positively stained cells in the total cell population exceeding the background staining signal. Each analysis was performed at least three times for verification, and the data represent the mean ± standard deviation from three to five experiments using cells of a given tissue from seven mice. Detection of intracellular cytokines: IL-2, IFN-γ, IL-4, IL-5, IL-10 and TNF-α.  The production of cytokines was measured through intracellular staining, and all the phenotypic assays of NALT and NP were performed in parallel as described in [8]. Statistical analysis.  The statistical analysis was performed using Mann–Whitney U-test, taking P < 0.05 as significant. The number of lymphocytes recovered from NALT following immunization of BALB/c mice with Cry1Ac was increased. The yield of lymphocytes from normal mice in NALT was 7.2 (±0.7) × 105 cells, while in the immunized group the number of cells obtained was 1.2 ± 0.3 × 106 cells (P < 0.05). The number of cells obtained from NP was slightly increased by immunization 1.4 (±0.

1/13). There was no specific difference in terms of frequency and type of seizures, AED regimen and clinical performance. Membrane traffic of SVs within nerve terminals involves major www.selleckchem.com/products/MK-2206.html trafficking proteins that are common constituents of all SVs and small protein families containing several isoforms that are differentially expressed in different parts of the nervous

system, such as SV2 proteins. In this study, we report for the first time the distribution of the three SV2 isoforms, SV2A, SV2B and SV2C, in the hippocampus of controls and TLE patients. Only a few studies have analysed SV2A expression in the human hippocampus [9, 19], cerebral cortex [9, 39] and cerebellum [9]. In this study, TLE patients with HS showed reduced SV2A expression in hippocampal areas of neuronal/synaptic loss but increased expression in the IML when mossy fibre sprouting occurs. This compares well with previous observations by van Vliet et al. [19]. Similar observations have been

made in rat models of temporal epilepsy and it has been suggested that SV2A loss could contribute to epileptogenesis and pharmacoresistance [10, 15-18]. In contrast, no significant SV2A expression change see more was found within or around epileptogenic brain tumours [35], foci of cortical dysplasia and cortical tubers [39]. A recent prospective study indicates, however, that SV2A expression in tumour and peritumoural tissue correlates with clinical response to LEV and predicts LEV efficacy in these patients [40]. In the adult rodent brain, SV2B has a wide distribution, but with Bumetanide some areas of restriction/exclusion, being barely detectable in the striatum and undetectable in the globus pallidus, cerebellar Purkinje cells, reticular nucleus of the thalamus, pars reticularis of the substantia nigra, and GCL in the hippocampus [3, 7]. This study shows that in human controls and TLE patients, SV2B distribution parallels synaptophysin and SV2A in the hippocampus, suggesting that most synapses contain both isoforms. The role of SV2B in epilepsy is unclear, as knockout SV2B−/− mice do not show an epileptic phenotype

and SV2B absence does not aggravate the phenotype of the SV2A deletion [2]. Like other SV2s, SV2B is not neurotransmitter specific but in one recent study, it was found to be associated preferentially with VGLUT-1 synaptic vesicles in the rat [7], a finding that contrasts with SV2B detection by in situ hybridization in both glutamatergic and GABAergic neurones [3] and also with our own findings. The preferential involvement of SV2A or SV2B in Ca2+-dependent vesicle exocytosis may be cell population specific as previous work has shown their differential distribution in neuronal and endocrine cells [3, 4, 21, 22, 41]. It may also reflect neurone maturation, as SV2B is not detected in the GCL in adult rats and mice although it is transiently expressed during development [3].

Moreover, TGF-beta1-JNK pathway can give rise to apoptosis and fibrosis. In this study, we investigated the effect of two natural active ingredients extracted from DFD, emodin and aconitine, on the tubular epithelial cells apoptosis and renal fibrosis via TGF-beta1-JNK pathway in RF rats. Methods: A rat model of RF was established by the administration of adenine (150 mg/kg) for 2 weeks. After that, some of them were received the combination of emodin and aconitine (0.1 g/kg), and some

others were given allopurinol (0.03 g/kg), respectively, in the morning for 3 weeks. During the treatment, adenine was administered to rats every 3 days to avoid a quick Selleckchem MK-8669 recovery of renal function. Age and weight-matched rats were used as normal. Body weight, proteinuria, UNAG levels, the blood biochemical parameters, renal histopathology damage and TUNEL-staining

were detected, respectively. Protein expressions of key markers in mitochondrial selleck screening library and TGF-beta1-JNK pathway were examined, respectively. Results: Adenine administration successfully induced mass proteinuria, heavy UNAG, severe renal dysfunction, and marked tubular histopathological damages in model rats compared with control. This was associated with tubular epithelial cells apoptosis, abnormalities in Bcl-2, Bax and cleaved caspase-3 protein expressions and activation of TGF-beta1-JNK pathway. The combination of emodin and aconitine treatment significantly prevented proteinuria, UNAG elevation, renal dysfunction and tubular histopathological injuries. The combined agents attenuated tubular epithelial apoptosis and reversely-regulated the abnormal protein expressions of Bcl-2, Bax and cleaved caspase-3. Furthermore, it suppressed the protein levels of TGF-beta1 as well as phosphorylated-JNK (p-JNK). We also found that allopurinol could improve abnormalities in blood biochemical and urinary parameters, tubular histopathological changes NADPH-cytochrome-c2 reductase and epithelial cells apoptosis. However, allopurinol could not perform as well as the combined

agents in ameliorating general status and keeping body weight. Conclusion: The combination of emodin and aconitine could protect adenine-induced tubular epithelial cells apoptosis and renal fibrosis in vivo, presumably via suppressing TGF-beta1-JNK pathway activation.

, 2007). Recently, MTB/RIF GeneXpert (Xpert) assay (Cepheid, JQ1 in vitro Sunnyvale, CA) has been a major breakthrough in the diagnosis of EPTB (Vadwai et al., 2011; Tortoli et al., 2012). Further details of this test

are discussed later in this review. EPTB exists in several clinical forms and important research findings related to their diagnosis by PCR are described as follows. Tuberculous (TB) lymphadenitis is the most common presentation of EPTB and has been shown in about 35% of EPTB cases (Mohapatra & Janmeja, 2009; Cortez et al., 2011). Most frequently, this disease involves the cervical lymph nodes followed by mediastinal, axillary, mesenteric, hepatic portal and inguinal lymph nodes (Sharma & Mohan, 2004). Diagnosis of TB lymphadenitis is challenging as it mimics the other pathologic processes (sarcoidosis, leprosy, fungal and NTM infections) and yields inconsistent histopathological findings in the absence of AFB (Osores et al., 2006; Derese et al., 2012). Fine-needle aspiration (FNA) cytology, a less invasive procedure than excision biopsy, has assumed an important role in the diagnosis of TB lymphadenitis (Chakravorty et al., 2005; Derese et al., 2012). However, the amount GDC-0068 nmr of material obtained in the FNA is usually so small that it is often inadequate to perform AFB smear and culture examination (Kidane et al., 2002; Mohapatra & Janmeja, 2009). FNA cytology

also has difficulty in differentiating TB from other granulomatous or NTM diseases (Baek et al., 2000). Several researchers have performed PCR from the remainders of FNA after cytological examination, and this clinical application of PCR along with FNA cytology could reduce the necessity for open biopsy as the process of biopsy is invasive and leaves unwanted scar tissues

in the neck causing aesthetic problems (Baek et al., 2000; Supiyaphun et al., 2010). Various gene targets such as IS6110, 16S rRNA gene, IS1081, 65 kDa and MPB-64 have been employed to diagnose TB lymphadenitis by PCR from FNA or formalin-fixed paraffin-embedded tissues with varying sensitivities and specificities (Totsch et al., 1996; Pahwa et al., 2005; Osores et al., 2006; Nopvichai et al., Phosphatidylethanolamine N-methyltransferase 2009; Sharma et al., 2010b; Cortez et al., 2011; Derese et al., 2012; Table 1). Within M. tuberculosis complex, M. tuberculosis and Mycobacterium bovis are the major causative agents of TB lymphadenitis. The rest of FNA after cytological evaluation has been used for PCR based on three gene targets to identify Mycobacterium at the genus (Antigen 85 complex gene), complex (IS6110) and species (pncA gene and allelic variation) levels in patients with TB lymphadenitis. It was found that PCR positivity was 87% at the genus and complex levels, 68.5% at species level for M. tuberculosis and 17% for M. bovis (Kidane et al., 2002). A nested PCR targeting hupB gene has also been documented from FNA specimens to differentiate M. tuberculosis from M. bovis (Verma et al., 2010).

To avoid these technical limitations and directly determine whether CR3 and or CR4 are critical for the development and progression of ECM, we used mice deficient in these receptors. We compared susceptibility and clinical severity of CR3−/− (23), CR4−/− (24) and wild-type mice in Plasmodium berghei ANKA-induced ECM as previously click here described (25). All mice used in this

study were on the C57BL/6 background. For these studies, P. berghei ANKA was maintained by passage in BALB/c mice (26). ECM was induced by injecting mice i.p. with 5 × 105 PbA-infected RBCs. Peripheral parasitemia was monitored on day 6 postinfection by Giemsa-stained, thin-blood smears. Mice were monitored twice daily for clinical signs of neurologic disease using the following scoring scale: 0, asymptomatic; 1, symptomatic (ruffled fur); 2, mild disease (slow righting); 3, moderate disease (difficulty righting); 4, severe disease (ataxia, seizures, coma); 5, find more dead. Mice observed having seizures were given a score of 4 regardless of other clinical signs of disease. Moribund animals were scored 4·5 and humanely sacrificed. Mice were classified as having ECM

if they displayed these symptoms between days 6 and 9 post-infection, had positive thin-blood smears and, had a corresponding drop in external body temperature or succumbed to infection. We found that CR3−/− and CR4−/− mice did not survive significantly longer than wild-type mice (P > 0·05, Log-rank test; Figure 1a,d) and that all three groups of mice succumbed to infection at the same rate. Disease severity in CR3−/− and CR4−/− mice was identical compared with wild-type mice and corresponded well to survival (Figure 1b,e). Interestingly, peripheral parasitemia was significantly elevated in CR3−/− (P = 0·0028, unpaired Student’s t-test), but not in CR4−/− mice compared with wild-type mice (Figure 1c,f). The latter results suggest a minor role for CR3 in parasite clearance, but not in survival or disease severity. The absence of an altered

disease phenotype in CR3−/− and CR4−/− mice raised questions regarding the role of other β2-integrin adhesion molecules in ECM. Previous studies have reported SPTBN5 minimal differences in the course of ECM through day 10 in CD11d−/− (αDβ2) mice (27) not unlike what we report here for CR3 and CR4. In contrast, LFA-1 (CD11a, (αLβ2), also a member of the β2-integrin family, is thought to play a key role in the development of ECM based on studies demonstrating significant protection from the development of ECM on treatment with anti-LFA-1 antibodies (21,22,28). To our knowledge, no one has directly assessed the role of LFA-1 in ECM using LFA-1−/− mice to verify these reports. Therefore, we performed ECM using LFA-1−/− mice (29).

Additionally, CFSE-labelled splenic CD4+ T lymphocytes from C57BL/6 mice treated with or without AZM for 3 days were cultured in MLR with allogeneic BALB/c BM-derived mDCs for 3 days. It was confirmed that expression of major histocompatibility complex (MHC) class II and co-stimulatory molecules (CD40, CD80 and CD86) on LPS-induced mDCs was elevated in comparison with imDCs (data not shown). We did not observe any differences in the dividing CFSElow CD4+ population between AZM-treated and untreated C57BL/6 mice in the allogeneic MLR (Fig. 3c). These data indicate that AZM does not inhibit donor lymphocyte functions ex vivo at the tested doses. Novel immunomodulatory agents

focused on NF-κB in host DCs [6-11, 20-22, 31] instead of the BGB324 conventional immunosuppressants targeted on donor T lymphocytes [1-5] have been reported to prevent or attenuate GVHD in allogeneic haematopoietic transplantation, including PF-562271 nmr in the histoincompatible setting. In this study, we used AZM – a macrolide antibiotic and a NF-κB inhibitor of murine DC maturation – alone for GVHD prophylaxis and showed that it inhibited acute GVHD significantly in MHC-incompatible bone marrow transplantation (BMT) without interfering with donor engraftment. AZM is active against a wide variety of bacteria and also acts as an anti-inflammatory agent by modulating the functions of DCs, monocytes

and/or macrophages [24, 35-37]. Previously, Sugiyama et al. [35] and our team [24] have reported that AZM inhibits the maturation and functions of murine bone marrow-derived DCs in vitro. We also showed that AZM, by inhibiting the NF-κB pathway in LPS-stimulated DCs and generating DCs with regulatory DC properties, blocks murine DC–T lymphocyte interaction in allogeneic immune systems [24]. In murine allogeneic

BMT models, recipient-type regulatory DCs, characterized by low expression levels of co-stimulatory molecules, moderate levels of MHC molecules, low production of IL-12, high production of IL-10 and Dichloromethane dehalogenase suppression of NF-κB activity even after stimulation with LPS, inhibited acute GVHD, mediated partly by IL-10, as a key regulator of anti-inflammatory responses [38, 39]. Sato et al. [38] also found that recipient-type regulatory DCs increased donor-type regulatory T cells (Treg) which produced IL-10 and resulted in protection from lethal acute GVHD. Additionally, we reported significantly increased IL-10 levels in co-cultures of allogeneic T lymphocytes and AZM-treated DCs [24]. The precise mechanisms underlying the findings presented in this report are unknown, because we did not analyse induction of Treg and/or plasma IL-10 of recipient mice treated with AZM, or for immunophenotypic or functional changes in DCs derived from recipients treated with AZM due to a numerical problem without in-vivo expansion stimulated with Flt3 ligand and/or other cytokines [11, 40, 41].

This could be attributable to the foreign

antigen expression. selleck kinase inhibitor Another important difference in the current study is the utilization of a frozen inoculum, mandated by the NIH; our prior study utilized freshly grown organisms centrifuged from stationary phase broth cultures. Virulence factors are regulated by temperature in a complex fashion in L. monocytogenes, and its ability to adapt to and grow at low temperatures is of importance for food safety, as reviewed recently (39). Some strains have a greater “growth lag phase” after cold storage (40). Cryotolerance (freeze/thaw tolerance) appears to be strain dependent, and growth temperatures may affect this (41). It is beyond the scope of this paper to further examine reasons for the poor immune responses observed. Live attenuated bacterial vectors for oral delivery of vaccine antigens have unfortunately not been highly successful in this or other human studies. Perhaps

Idasanutlin chemical structure these highly-attenuated, safe strains could be used in other applications requiring transient delivery of other molecules or pharmacologic “payloads” to the gut lumen.

“Considerable interest has emerged towards phagocytosis of apoptotic cells, due to its intricate

molecular mechanisms and important regulatory functions in development, homoeostasis, and immune tolerance. Impaired clearance of apoptotic cells leads to immune-mediated STK38 disorders. Current quantification methods of the engulfment of apoptotic cells by macrophages are potentially flawed by several limitations. Adherent macrophage populations are overlaid with apoptotic targets in suspension and then co-cultured for a definite period, which may give rise to two different features: (1) engulfed and (2) non-engulfed macrophages that are surface-bound cell populations. Rigorous washing to dislodge surface-bound apoptotic cells before assessment of phagocytosis may lead to loss of phagocytes, thereby skewing the apparent magnitude of the overall phagocytic response.

B and T cells also showed altered secretion of cytokines and chemokines after LL-37 and LPS treatment compared with LPS alone 14. In B cells, LL-37 limited class switching and cell proliferation after LPS/IFN-γ treatment 15. Immunizing mice with OVA and mCRAMP led to an increase in specific anti-OVA

IgG as compared with immunization with OVA alone 13, while a fusion of LL-37 and M-CSFRJ6-1 improved the specific immune response to tumors in this website mice 16. The extent to which these responses are influenced by APCs and innate immunity is still unclear and many aspects of the relationship between cathelicidins and the adaptive response are largely unknown. Additionally, most in vivo studies have focused on injecting cathelicidin into rodents instead of examining its endogenous effects on adaptive immunity. A study by Kin et al. 17 in this issue of the European Journal of Immunology brings new understanding to the role of cathelicidins in adaptive immunity by isolating populations of B and T cells

from peritoneal lavage and the spleen in WT and Camp−/− mice lacking the gene for mCRAMP. Intriguingly, it was found that the response to, and expression of, IL-4 was altered in the Camp−/− mice and this affected both T and B cells. IL-4 is a key regulator of adaptive immunity that leads to an increased humoral response by promoting Th2 cell development 18. Under IL-4-induced

buy Gefitinib Metformin solubility dmso Th2 conditions, IL-4 was significantly increased in the Camp−/− T cells and the expression was reduced to WT levels when mCRAMP was added. In contrast, CD4+ T cells from Camp−/− mice showed a similar expression of IFN-γ as WT CD4+ T cells when both were cultured under IFN-γ-induced Th1 conditions 17. IL-4 also enhances class switching in B cells, increasing IgG1 and IgE expression in mice 19. In the Kin et al. study 17, B cells isolated from WT and Camp−/− mice showed no differences in IgM and IgG3 expression when cultured with LPS, or in IgG2c levels when CD40L/IFN-γ was used as a stimulus. Surprisingly, when the B cells were cultured with CD40L/IL-4, the Camp−/− cells showed decreased IgG1 and IgE expression. The antibody levels were restored to those of WT cells when mCRAMP was included in the culture conditions. The decreased IgG1 production was determined to be from reduced mRNA expression rather than changes in class switching. Kin et al. 17 further demonstrated a relationship between mCRAMP and B and T cells by injecting mice with type 1 and 2 antigens or T-cell-dependent antigens 17. T-cell-dependent antigens require Th2 cells to activate B cells and produce antibody, whereas type 1 and 2 antigens are T-cell independent and do not require a Th2 signal.

Functional domains of all component genes were found to be intact in the Hymnenolepis genome, and RNA-seq data indicate www.selleckchem.com/products/bmn-673.html the genes are expressed throughout both phases of the life cycle, suggesting all three pathways are functional in parasitic flatworms (131). RNA-seq data also show Wnt1 to be differentially expressed in adult worms, consistent with its role as a segment polarity gene in some organisms (e.g. Drosophila). Although a few ParaHox orthologs have been characterized in free-living flatworms (151), none of the three genes (Gsh, Xlox, Cdx) is found in parasitic flatworms (128,141). They thus lack entirely

the additional anterior, central, and posterior regionalizing morphogens found in most Metazoa, and this may again reflect their lack of overt axial differentiation as compared to other animals groups. Moreover, the posterior ParaHox gene is a downstream target of Wnt signalling in the segmentation mechanisms of flies and mice (152), and thus, if the Wnt pathway is also involved in tapeworm segmentation, their lack of ParaHox orthologs makes it clear that the mechanism is modified, if not in fact distinct,

from the canonical bilaterian mechanism of segmentation. Additional cDNA samples currently being characterized at the WTSI for RNA-seq analyses will enable Selleckchem Osimertinib comparisons to be made regarding differences in expression along the progressively maturing length of the adult tapeworm body. In this way, we can efficiently characterize the entire transcriptomes associated with the segmenting neck region, maturing strobila and gravid proglottides, and examine differences in gene expression in silico via RNA-seq. Data will enable a comprehensive examination of the gene systems active during different phases of their development, including those regulating the

process of segmentation, for which we have little information at present (e.g. 153). Cestodology has entered the era of nuclear genomics Methocarbamol and transcriptomics. With the E. multilocularis genome almost finished and those of E. granulosus, T. solium and H. microstoma in advanced draft versions, a significant body of cestode genome information is now publicly available. Although annotation is still ongoing, we can already state that there is a wealth of information on potential immunomodulatory factors, promising targets for the development of improved chemotherapeutics, and signalling pathways involved in host-dependent development and morphogenesis in cestodes. Comparisons with trematodes and free-living flatworms will yield valuable information concerning genomic rearrangements and gene gain/loss associated with the evolution of parasitism, allowing us to identify common factors involved in host immunity. The projects also demonstrate that genome characterization in tapeworms is manageable thanks to their comparatively small size and low amount of repetitive and mobile genetic elements.
