Autoimmune T cells play a key role as regulators and effectors of organ-specific autoimmune disease. In multiple sclerosis (MS), activated T cells specific for myelin components produce a plethora of inflammatory cytokines and mediators that contribute to myelin damage. The production of proinflammatory and regulatory cytokines by peripheral blood cells from patients with active and stable MS and healthy controls were examined. The results show that TNFa production was somewhat elevated in active MS with no significant increase in the level IFNg, whereas in the chronic phase the anti-inflammatory cytokines IL-10 and TGFb increased, accompanied by a reduction in IFNg when stimulated by myelin basic protein.

SummaryGlu-plasminogen binds to platelets; the monocytoid line, U937, and the human fetal fibroblast line, GM1380 bind both plasminogen and its activator, urokinase. This study assesses the interaction of these fibrinolytic proteins with circulating human blood cells. Plasminogen bound minimally to red cells but bound saturably and reversibly to monocytes, granulocytes and lymphocytes with apparent Kd values of 0.9-1.4 μM. The interactions were of high capacity with 1.6 to 49 × 105 sites/cell and involved the lysine binding sites of plasminogen. Both T cells and non-rosetting lymphocytes and two B cell lines saturably bound plasminogen. Urokinase bound saturably to gianulocytes, monocytes, non-rosetting lymphocytes and a B cell line, but minimally to T cells, platelets and red cells. Therefore, plasminogen binding sites of high capacity, of similar affinities, and with common recognition specificities are expressed by many peripheral blood cells. Urokinase receptors are also widely distributed, but less so than plasminogen binding sites. The binding ol plasminogen and/ or urokinase to these cells may lead to generation of cell- associated proteolytic activity which contributes to a variety of cellular functions.
