Serum immunoinhibitory factors in stroke patients

Immunoinhibitory factors in the sera of stroke patients were studied by an analysis of their capacity to influence the in vitro proliferative response of T cells. The evidence was obtained that the sera from stroke patients exhibited inhibitory activity on T cell proliferation. Although the nature of these inhibitory factors was not analyzed, it was clearly shown that their activity correlated with the degree of neurological defects, indicating that their determination may be of some prognostic value.
