Co-cultivation of human thymocytes with homologous thymic epithelial cells (TEC) resulted in apoptosis of thymocytes and increase of CD25 expression. TEC supernatant also induced these effects. Fraction of apoptotic cells was enriched by CD69+ cells but not by CD95+ cells. Thymocytes of mice MRL-lpr/lpr bearing mutant form of gene Fas were sensitive to(More)
Oxidized forms of fibrinogen similarly to initial non-oxidized fibrinogen induced expression of P-selectin and ICAM-1 cell adhesion molecules in the cultured endothelial cells derived from human umbilical vein. The effect of oxidized fibrinogen on the expression of adhesion molecules was more pronounced. These data attest to more active participation of(More)
Clinical and immunological investigation with immune status evaluation of three groups of adult population of Bryansk Region was performed. The first group included 165 persons living in Vyshkov (settlement of town type in Bryansk Region) contaminated with radionuclides as a result of Chernobyl accident. The second group included 68 persons living in(More)
Using flow cytometry we looked for a thymocyte subpopulation responsible for the development of thymus urgent recovery and secondary atrophy in sublethally irradiated mice (4 Gy). It was expected that the number of these cells would grow before the urgent recovery peak and would drop during secondary atrophy. It was found out that DN3 thymocytes were the(More)
The hypothesis is formulated, which explains genesis of long-lasting disturbances in the immune system of the persons affected by factors of Chernobyl disaster. Immunological alterations which are displayed at the late time after action of radiation in doses 0.5 Gy or lower are not a result of direct damage of the cells of immune system by irradiation.(More)
The effect of the innovative product Neolactoferrin, a natural combination of recombinant human lactoferrin (90%) and goat lactoferrin (10%) isolated from the milk of transgenic goats carrying the full-length human lactoferrin gene, on human immune system cells was studied. Neolactoferrin enhanced the production of IL-1β. Neolactoferrin saturated with iron(More)
AIM To elucidate the effects of combined therapy with glucocorticosteroids (GCS) and recombinant human interferon alpha or gamma (IFN) on proliferative responses of T-lymphocytes activated by various surface molecules (CD3 and CD2) in patients with SLE. MATERIALS AND METHODS A 3-month trial entered 3 groups 15 patients each with verified SLE by APA(More)
AIM To study activation of T-lymphocytes by the CD3 (antigen-dependent) and CD2 (non-antigen-dependent) routes in patients with systemic lupus erythematosus (SLE). MATERIALS AND METHODS Peripheral blood mononuclears were studied in 66 patients with SLE and 27 donors. Proliferative response to activation by anti-CD3, anti-CD3+(More)
