Amino acid sequence of HSV gC from residues 89-179 based in part on Mardberg et al. (2001). B. A larger scale diagram depicting the N-terminal 373 residues (out of 511), showing the first two disulphide bonds and antigenic (Ag) sites I and II. Residues found to be essential to heparin binding are shown as shaded circles in (A). Linker insertion points that resulted in loss of C3b binding are indicated with a black lightning bolt (A and B), while insertions that did not abrogate C3b...

C4C2dependent MASP2 route C4C2bypass MASP1 route

Two routes are present in lectin pathway. Different oligomerizations of MBL exist in serum. Mainly trimer of MBL, termed as MBL-I associate with MASP-1 and sMAP, whereas tetramer of MBL, termed as MBL-II associate with MASP-2 and MASP-3. MASP-1 can trigger the complement activation in absent of C4 C2 by direct activation of C3 (C4 C2-bypass, MASP-1 route). In another route, it is essential to activate C4 and C2 by MASP-2 (C4 C2-dependent, MASP-2 route). MASP-1 might be able to enhance...

This has occurred to the researchers investigating in the complement field the anaphylatoxins C5a, C5a-desArg, and C3a and their receptors the C5a-receptor...

Differential Regulation of Key Signaling Molecules in Innate Immunity and Human Diseases

Egg Sinker Leader Combo

1 Department of Biology, Virginia Tech, Blacksburg, VA 24061-0346, lwli vt.edu Following the discovery of Toll-Like-Receptors (TLRs) and related downstream signaling molecules, the field of innate immunity and inflammation has drawn immense interest. Human hosts can specifically respond to distinct non-self molecules via TLRs and illicit complex yet specific responses through the expression of diverse cellular mediators such as cytokines, chemokines, complement factors, and co-stimulatory...
