Some in vitro functions of purified T and B cells from PPD- and Candida albicans-negative sarcoidosis patients were analyzed. It appears that in those patients there is: 1) A decrease in the absolute number of T lymphocytes and an increase in the number of B cells; 2) a rather normal response of T lymphocytes to PHA and Con A; 3) a rather normal capacity of T and B cells to produce MIF in vitro; and 4) an ability of T cells from sarcoid patients (but not B cells) to produce LMF. These results suggest that the frequent deficit in cell-mediated immunity observed in sarcoidosis seems to correlate with a quantitative deficit in T cells. The cause of this T-cell deficit is unknown.
