abstract：:The growth and differentiation of cytolytic T lymphocytes (CTL) is regulated by soluble growth hormones, of which interleukin-2 (IL-2) is considered to be of prime importance. Here we report that the lymphokine B-cell stimulatory factor (BSF-1 or interleukin-4) also has profound effects on the generation of these func...
