Abstract
The decrease in interferon gamma expression by lymphocytes during aging is one of the main mechanisms leading to an immunodeficiency state in the elderly. Cell-penetrating geroprotective peptide Ala-Glu-Asp-Gly has the ability to activate proliferation of lymphocytes in the thymus during its aging. The nucleotide sequence that complementary contacts with Ala-Glu-Asp-Gly has been found in the promoter region of interferon gamma gene. Thus, the immunoprotective effect of the peptide can be explained by activation of interferon gamma production in T cells.
