UNLABELLED: The aim of the study was to assess the role of costimulatory molecules in pathogenesis of nonallergic bronchial asthma.
MATERIAL: The studied group consisted of 30 patients with nonallergic asthma, 24 with nonallergic asthma and recurrent respiratory tract infections and 20 healthy controls.
RESULTS: In nonstimulated and lipopolysaccharide (LPS) stimulated cultures of control group the mean value of CD16+ + 56+ CD28+ subpopulation were significantly decreased compared to values in both types of asthma. Similar dependence was observed in cultures of asthmatic patients with infection and healthy person, stimulated with IL-15 and in CD4+CD28+, CD8 +CD28+ and NKCD28+ cultures from all studied groups, stimulated with LPS plus IL-15. In nonallergic asthma and infection asthma mean values of CD4 +CD152+ and CD16+ +CD56 +CD152+ from nonstimulated and IL-15 stimulated cultures were significantly increased compared to analogical values in control group.
CONCLUSION: The results of our studies suggest that in nonallergic asthma the disturbed expression of costimulatory molecules may play an important role in pathomechanism of disease.
