FIG 7.

B cell ligand and cytokine level in serum of asymptomatic and symptomatic herpes. Asymptomatic (n = 20) and symptomatic (n = 20) patient serum samples were assayed for cytokines involved in B cell development. Graph showing serum level of APRIL (B cell proliferation inducing ligand), BAFF (B cell-activating factor), and IL-10 (B regulatory cell cytokine) (A) as well as IL-21 (involved in expansion and differentiation of plasma cells), IL-7 (B cell development cytokine), and TNF-β (B cell development cytokine) by Luminex. Statistical analysis was done using Student's t test. NS, not significant.
