ABSTRACT
This study investigated in vitro effects of cocaine on the function of T and B lymphocytes, natural killer cells and macrophages in a mouse model. In mature C57BL/6J mice (60-90 day-old), splenocytes were cultured with cocaine at different concentrations ranging from 4 to 64 microg/ml for 24 h. The exposure to cocaine in vitro was found to affect (1) T cell function, with reduced responses to stimulation of Con-A, PHA and Interleukin 2, and decreased production of gamma-IFN; (2) B cell function, with reduced response to LPS; (3) natural killer cell function, with attenuated killing capacity; (4) monocyte-macrophage function, with decreased ability to inhibit the growth of tumor cells. The results of the study indicated a direct cocaine effect on four major immune competent cells, and the generally suppressive effects of in vitro cocaine exposure may be related to its in vivo action on the immune system.
