Expansion of cyclophosphamide-resistant cytotoxic precursors in vitro and in vivo by purified human interleukin 2

J Immunol. 1983 Aug;131(2):806-9.

Abstract

Precursors of cytotoxic lymphoid cells obtained from mice treated with cyclophosphamide (CY) can be expanded in culture by alloantigens in the presence of purified human interleukin 2 (IL 2). Similarly, IL 2 delivered in vivo in a rate-controlled manner enhances cytotoxic activity in mice that are immunosuppressed by high doses of CY. The effector cells are Thy-1.2+ and are not elicited in the absence of antigen.
