title: Possible 110 kDa receptor for interleukin 2 in the chicken.
abstract: Chicken lymphoblasts were generated from spleen cells which had been incubated with concanavalin A (Con A) for 48 h. Monoclonal antibodies (mAbs) were produced by immunizing mice with 48-h Con A lymphoblasts. These antibodies were used to identify chicken lymphokine receptors on Con A-activated lymphocytes. The cellular enzyme immunoassay (EIA), with lymphoblasts and spleen cells as the target cells, was used to select for specific mAbs. One mAb was found by EIA to have a strong response against the lymphoblasts but weak against resting spleen cells. By immunofluorescence staining, it reacted strongly with lymphoblasts and weakly with resting spleen, erythrocytes, and bursal cells. This mAb was also shown to inhibit the lymphokine activity present in conditioned medium that was collected from 24-h cultures of Con A-activated spleen cells. By immunoprecipitation, this mAb precipitated a lymphoblast surface antigen with a molecular weight of about 110 kDa. This receptor may be analogous to the putative interleukin 2 gamma subunit recently described in human and mouse cell lines.
