Abstract
Cyclophosphamide treatment of chickens during early extraembryonic life selectively inactivates B cells as indicated by the induction of agammaglobulinemia and the lack of proliferative response of their spleen cells to anti-immunoglobulin. T cell functions as measured by the response to phytomitogens, anti-thymocyte serum and irradiated allogeneic cells in the mixed leukocyte reaction were found to be intact. However, the in vitro proliferative response to specific antigens was significantly diminished in agammaglobulinemic chickens which suggests that B cell participation may be required for this response.
