CD69 molecule is the earliest antigen of T lymphocytes activation. We have studied the ex-pression of CD69 on LPS-stimulated T cells in nonatopic bronchial asthma. We have found that CD69 expression on freshly isolated peripheral blood T cells in nonatopic asthma patients was increased compare to control group (4.74 +/- 1.55/3.05 +/- 1.31) and the difference was statistically significant (p < 0.01). Monocytes added to nonstimulated T cell cultures increased 3-4 times the expression of CD69 and about 10-times in LPS-stimulated T lymphocytes.
