Figure 5.
Antigen-specific T cell proliferative responses and T helper cell cytokine secretion from paired adenoids and tonsils. Proliferative responses of tonsillar and adenoid mononuclear cells to diphtheria toxoid (DT), tetanus toxoid (TT), influenza virus, or C. albicans antigens were determined by 3H-thymidine uptake of cultured cells. Proliferative responses are expressed as the mean of the stimulation index (SI) and cytokine levels as the mean of duplicate ELISA assays and are representative of paired specimens which, in addition to C. albicans, responded to at least one antigen. The same pair of adenoids and tonsils was used to illustrate responses to influenza and C. albicans.
