Correlation analysis between CD100 expression on B cells and serum HCV-RNA levels during the early phase of IFN-alpha treatment.(A) Representative dot plots of the CD100 percentages in CD5+ and CD5- B cell subsets in one of the six HCV patients are shown. (B) The CD100 expression on CD5+ (open circles) and CD5- B cells (filled circles) and serum HCV-RNA levels (filled rhombs) immediately before and seven days after IFN-alpha /RBV treatment is shown for six chronic HCV-infected patients.

The effect of IFN-alpha on CD100 expression in B cells and their subpopulations.(A) CD100 expression on CD5+ and CD5- B cells from one representative, healthy donor before and after IFN-alpha stimulation of PBMCs. (B) CD100 expression alterations in B cells and their subsets after 24-h stimulation with 0.01, 0.1, 1, 10, 100 or 1000 ng/ml of IFN-alpha. Two of six representative individuals are shown. (C) CD100 expression at different time points: 0, 2, 6, 12, 24 and 48 h on B cells and their subsets after stimulation with IFN-alpha at a concentration of 0.1 ng/ml (open circles), 10 ng/ml (filled squares) or 100 ng/ml (filled triangles). One of the six representative individuals is shown. (D) The mean fluorescence intensity (MFI) of CD72 expression on B cells stimulated with different concentrations of IFN-alpha.

Background: Semaphorin 4D/CD100

Semaphorin 4D (Sema4D/CD100, previously sem J, G or C-like 2) is a widely expressed 150 kDa type I transmembrane glycoprotein of the Class 4 Semaphorin family with activity in the immune and nervous systems. The 861 amino acid (aa) Semaphorin 4D contains a 710 aa extracellular domain (ECD) with a sema domain and an immunoglobulin-like domain. Within the ECD region used as an immunogen, mouse Semaphorin 4D shares 87% and 93% aa identity with human and rat Semaphorin 4D, respectively. A soluble, active 120 kDa form is produced proteolytically upon activation of B and T cells. Semaphorin 4D binds CD72 on B and dendritic cells and Plexin B1 elsewhere. In developing neurons, Semaphorin 4D assists in guidance. Semaphorin 4D is proangiogenic when expressed by tumor‑associated macrophages.
