Abstract
Macrophages are the key thymic cells that take part in the antigen-independent differentiation of T-lymphocytes and their further selection. The level of macrophages indicates changes in the functions of the organ under study. As an essential trace element, selenium is part of a variety of proteins and enzymes, which perform cytoprotective, antimutagenic, and anticancerogenic action. Selenium also plays a significant role in the functioning of the immune system, increasing the activity of natural killers, production of interleukins, and stimulation of phagocytosis. This study was aimed at investigating the response of thymic macrophages to the administration of selenium and a chemical carcinogen. During the experiment, an increase in the level of CD68-positive cells was revealed in all experimental animals receiving selenium and a carcinogen, as well as under their combined action. The observed effects were assumed to be related to the immune-stimulating effect of selenium.
