THE INVOLVEMENT OF LEPTIN IN THE REGULATION OF PROGRAMMED CELL DEATH IN PERSONS WITH DYSLIPIDEMIA

Indicators of programmed cell death (apoptosis) of immunocompetent cells of peripheral blood in the conditions of various level of a leptin at persons with a dislipidemiya are studied. Research was conducted with observance of the main standards of biomedical ethics. For realization of a goal two groups of the examined persons were allocated: with conditionally raised (>25 ng/ml, n = 13) and conditionally lowered (<10 ng/ml, n = 13) the content in blood of a leptin. Groups were almost equivalent on age (52,5 ± 1,4) and (50,7 ± 2,4) years and a sex (woman). Apoptosis of lymphocytes was estimated by method of a flowing laser tsitoflyuorimetriya with use FITC-marked of an anneksin of V ("Beckman Coulter", USA). Determination of concentration of a leptin, cytokin and IgE carried out to blood by method of the solid-phase immunofermental analysis. In dabs of blood painted according to Romanovsky-Gimz studied a monocytogramma and to a neutrogramma. The maintenance of phenotypes of lymphocytes was determined by method of a double peroksidazny tag with use of monoclonal antibodies. Research type retrospective, selections casual, one-stage. Population - inhabitants of the north of the European territory of Russia. Borders of normal distribution of quantitative indices defined by means of Shapiro criterion - Uilka. Reliability of distinctions between groups was estimated by means of parametrical t-criterion of Student and Uilkokson criterion. It is established that at increase of the maintenance of a leptin the differentiation and apoptosis of lymphocytes and neutrophils accrues; intensity of apoptosis and proliferation of monocytes does not change, but processes of their maturing and activization amplify. On this background concentration of IgE and IFN-γ that is also associated with accumulation of a leptin in blood increase.
