Abstract：
:Morphometric analysis of structural and functional changes in the human mesenteric lymph nodes during aging revealed the development of fibrous connective tissue, fragmentation of the lymphoid parenchyma, the absence of follicles with germinal centers, and a decrease in the level of lymphocyte proliferation, which was confirmed by the absence of Ki-67+ cells. The paracortical zone lacked CD4+ T helpers that regulate both cellular and humoral immunity. High content of plasma cells and eosinophilic granulocytes in the medullary cords and sinuses reflects the development of autoimmune processes associated with a decrease in the number of regulatory T lymphocytes. The development of fibrous connective tissue in the sinus system complicates lymph flow through the lymph node and impairs lymph filtration.
