Candida Pra1 binds human ligands, including (i) fibrinogen, an extracellular matrix protein [[23]], (ii) Factor H and FHL1 (factor H-like protein 1), two plasma proteins that regulate the alternative complement pathway [[24]], (iii) C4BP, the soluble regulator of the classical pathway regulator

[[25]], (iv) C3, a central complement protein and several C3 activation fragments [[26]], (v) plasminogen, the coagulation cascade component [[24]], and (vi) the integrin CR3 which Wnt inhibitor is a central inflammatory receptor [[27]]. Because of this interaction with a diverse array of human immune effectors, Candida Pra1 is considered a central fungal virulence factor, blocking complement activation and effector functions at multiple steps [[15, 28]]. Cheng et al. [1] now describe that Candida Pra1 blocks this complement and PBMS-mediated cytokine response. DAPT Given that, in evolutionary terms, complement is one of the oldest elements of innate immunity, the reporting of novel exciting complement effector functions – especially those that link innate and adaptive immunity – predicts that in the future additional important aspects of the complement system will be identified. These new facets,

in combination with already existing concepts, will reveal further complexity of the intense immune battle between the human host and pathogens like C. albicans.

“Helicobacter mafosfamide pylori CagA protein is considered a major virulence factor associated with gastric cancer. There are two major types of CagA

proteins: the Western and East Asian CagA. The East Asian CagA-positive H. pylori infection is more closely associated with gastric cancer. The prevalence of gastric cancer is quite low in the Philippines, although Philippine populations are considered to originate from an East Asia source. This study investigates the characteristics of the cagA gene and CagA protein in Philippine H. pylori strains and compares them with previously characterized reference strains worldwide. The full-length cagA gene was sequenced from 19 Philippine isolates and phylogenetic relationships between the Philippine and 40 reference strains were analyzed. All Philippine strains examined were cagA positive, and 73.7% (14/19) strains were Western CagA-positive. The phylogenetic tree based on the deduced amino acid sequence of CagA indicated that the Philippine strains were classified into the two major groups of CagA protein: the Western and the East Asian group. These findings suggest that the modern Western influence may have resulted in more Western type H. pylori strains in the Philippines.
