ABSTRACT
The involution of lichen sclerosus (LS) affected tissues may be the effect of suppression exerted by T lymphocytes which are involved in the pathogenesis of this disease. Inflammatory infiltrates in the affected regions of the skin consist mainly of CD3+ lymphocytes consist with diminished number of CD3+/CD26+ subsets. We revealed the diminished ROI production by peripheral blood, granulocytes after receptor dependent and receptor independent stimulation. The diminished number both of CD3+/CD25+ and CD3+/CD26+ in peripheral blood baseline increase of IL-12 and stimulated increase of IL-2, IL-5, IL-10 and TNF-α production by peripheral blood lymphocytes were also noted. We postulate that immunereactions are involved in LS pathogenesis.
