摘要
The insulin-like growth factors I and II (IGF-I and IGF-II) promote proliferation and differentiation of many cell types. We report that recombinant IGF-I and IGF-II augment both the lectin- and anti-CD3-induced proliferation of human peripheral blood mononuclear cells (PBMC) at concentrations proportional to their binding affinities. IGF-I and IGF-II also augmented the lectin-induced proliferation of purified T lymphocytes. Effects of IGF-I were found in cultures of T cells vigorously depleted for monocytes and supplemented with saturating concentrations of interleukin-1. The latter results indicate that the effect of IGF-I on the proliferation of T lymphocytes can occur independent of monocytes or monocyte-derived factors.
