Interleukin 4 counteracts the interleukin 2-induced proliferation of monoclonal B cells
B cells from patients suffering from B-type chronic lymphocytic leukemia (B-CLL) are susceptible to the effects of several interleukins. Using the cells from 12 different patients we show that IL-4 does not synergize with anti-mu antibody for the enhancement of DNA synthesis. Moreover IL-4 profoundly (90%) suppresses the response to IL-2 in the 10 patient responders to this interleukin. This su...
متن کاملInterleukin 2-induced proliferation of leukemic human B cells
The proliferative responses of purified leukemic human B cells from nine B cell chronic lymphocytic leukemias to recombinant interleukin 2 (IL-2), spontaneously, and after preactivation by Staphylococcus aureus Cowan I (SAC) or anti-mu antibodies were studied. Three patterns of response were observed: (a) no response (three cases); (b) a moderate spontaneous response enhanced by anti-mu (one ca...
متن کاملInterleukin 4 inhibits the proliferation but not the differentiation of activated human B cells in response to interleukin 2
The combined effect of IL-4 and IL-2 on proliferation of anti-IgM antibody or Staphylococcus aureus strain Cowan I (SAC)-preactivated B cells was investigated. It was observed that in most cases, rIL-2 used at optimal concentration induced higher levels of tritiated thymidine ([3H]TdR) uptake than rIL-4 used at optimal concentration. When rIL-4 and rIL-2 were added together, it was repeatedly f...
متن کاملEnhancement by interleukin 4 of interleukin 2- or antibody-induced proliferation of lymphocytes from interleukin 2-treated cancer patients.
Systemic interleukin 2 (IL-2) and IL-2-activated lymphocytes have induced tumor regression in some cancer patients. The IL-2-activated cells have usually been generated by obtaining peripheral blood mononuclear cells (PBMC) from cancer patients shortly after systemic IL-2 therapy and culturing them with IL-2 in vitro. In an effort to augment the ex vivo generation of such cells preactivated in ...
متن کاملEffect of Vitamin D treatment on Interleukin-2 and Interleukin-4 Genes expression in Multiple Sclerosis
Introduction: Multiple sclerosis is a chronic inflammatory disease of central nervous system. The etiology of MS is slightly known, but genetic and environmental factors are reported. Vitamin D regulates gene expression and affects target cell functions. The aim of this study was to investigate the expression variation of IL-2 and IL-4 genes under vitamin D supplementation in patients with mult...
