Lack of correlation between the number of circulating B cells and the concentration of serum antibodies reactive with the HIV-1 envelope glycoprotein.
Cells obtained from the peripheral blood of HIV-infected patients and volunteers immunized with HIV-1 vaccines are commonly used to study anti-viral responses, since lymphocytes from the central lymphoid organs are difficult to obtain. Analyses involving PBMC implicitly assume that circulating B cells provide an accurate reflection of the systemic humoral response induced by the HIV antigens. We examined this assumption by comparing the number of B cells secreting IgG anti-gp160/120 antibodies in the peripheral circulation with serum antibody titers. Results indicate that neither the magnitude nor duration of the serologic response detected in HIV-infected patients or gp160/gp120-immunized volunteers reproducibly correlates with the number of B cells secreting anti-envelope antibodies in the blood.
