Changes in lymphocyte subpopulations were investigated in guinea pig lymph nodes during the development of contact sensitivity to 2,4-dinitrofluorobenzene (DNFB) and following the injection of cyclophosphamide (CY; 300 mg/kg) using a panel of monoclonal antibodies against guinea pig lymphocyte surface markers. Application of a sensitizing dose of DNFB to the ear resulted in a significant increase in the number of cells recovered from the draining auricular and cervical lymph nodes, 4 and 6 days post sensitization. A significant increase in the number of cells in the contralateral cervical node was found at day 6 but not at day 4. At 4 days postsensitization the proportions of Ia positive lymphocytes were higher than those of immunoglobulin positive B cells in the draining auricular and cervical node and the contralateral cervical lymph nodes suggesting T-cell "activation". Four and six days after sensitization there were no significant changes in the proportions of Pan T and T suppressor/cytotoxic (Ts/c) positive lymphocytes in the draining auricular and cervical lymph nodes. Although contact sensitivity is "classically" a T-cell mediated phenomenon there was a significant increase in the proportion of B cells found in the draining auricular node 4 days after sensitization as compared to the "normal" auricular node. 1, 2, 3 and 7 days after injection of CY there was a significant depletion in the proportion of B-lymphocytes in the cervical lymph node. This effect was maximal between 2 and 3 days after CY and was paralleled by an increase in the proportion of Pan T positive cells.(ABSTRACT TRUNCATED AT 250 WORDS)
