Roles of leptin and ghrelin in the regulation of the phenotype and cytokine production by NK cells from peripheral blood

详细

Both leptin and ghrelin used separately at the concentrations corresponding to trimesters II–III of pregnancy increase the number of CD56^bright NK cells in mononuclear cell suspension; their combination also enhances the L-selectin expression on the surface of these cells in the culture. These hormones do not affect the production of TGF-β1, IL-17А, or IFN-γ by NK cells, and they inhibit the production of IL-10. Leptin decreses the IL-4 production by NKp46⁺ cells, but the presence of ghrelin abrogates this effect.
