Expression of the Ag-F differentiation antigen on T-lymphocyte blasts and cytotoxic cells.

In conclusion, we have demonstrated that Ag-F antigen is not present on cytotoxic splenocytes generated in vivo. Furthermore, we have preliminary evidence that mitogen- and MLR-activated T cells are both Ag-F negative and positive; however, proliferation of some Ag-F-positive precursors may be inhibited in whole lymph node populations.
