Antibody responses to pneumococcal polysaccharides are decreased in aged mice. Using a system to measure murine antibody responses to the Pnu-Imune vaccine, here we demonstrate that interleukin-10 (IL-10) has an adjuvant effect in enhancing the vaccine response in the aged. IL-10 increased the vaccine responses of B cells from aged mice in vitro only if either T cells or macrophages were also present...
CD4 + T cells from mice with murine AIDS (MAIDS) have been shown to be unable to respond to TCR stimulation as measured by proliferation, IL-2 production, or IL-2R upregulation, although responsiveness was restored with PMA and ionomycin. In this report we have demonstrated that the inability of MAIDS CD4 + T cells to respond to CD3 stimulation was not associated with reduced surface...
