[Expression of interleukin 2 receptors in in vivo Epstein-Barr virus transformed B lymphocytes].

Interleukin-2 (IL-2) enhances the proliferation of in vivo Epstein-Barr virus-(EBV)-transformed B-cells from patients with a present or past history of infectious mononucleosis. In contrast, there is less expression of functional IL-2 receptors on EBV-transformed B-cells from patients with rheumatoid arthritis. These results suggest differences in the involvement of B-cells in EBV-associated diseases.
