Background. Dates about the content of natural killers in psoriasis are important for understanding the processes of their migration to the lesion. The aim of the work was to study the content of various phenotypes of natural killers in patients with psoriasis.
Materials and methods. Clinico-immunological examination of 82 patients with vulgar and exudative forms of psoriasis in the progressing and stationary stage (39 women and 43 men) aged 20 to 60 years was carried out. As a control group, 50 practically healthy people (of them 28 women and 22 men) who did not have acute or exacerbation of chronic diseases were examined at the time of the examination. The concentration of lymphocytes containing the molecules of L-selectin (CD62L), ICAM-1 (CD54), LFA-1 (CD11a), LFA-3 (CD58), PECAM-1 (CD31), as well as phenotypes of lymphocytes with the phenotypes CD56 + CD16-, CD56 + CD16 +, CD56-CD16 +.
Results. In the conditions of psoriasis, a noticeable decrease in the absolute number of lymphocytes bearing the LFA-1 and PECAM-1 molecules participating in the «strong adhesion» and «transmigration» stages is recorded. Differences in the contents of CD56 + CD16, CD56-CD16 + and CD56 + CD16 +, as well as in concentrations of lymphocytes with the molecules of L-selectin, LFA-3 and ICAM-1, were not revealed. However, the conducted correlation analysis showed statistically significant correlations.
Conclusions. The absence of differences in the content of NK cells in patients with psoriasis is a compensatory manifestation of enhanced maturation in the red bone marrow in response to active migration to the lesion, which ultimately provides the required level of NK cells.
