MORPHOLOGICAL FEATURES OF IMMUNOCOMPETENT CELLS UNDER TEMPERATURE INFLUENCE

Abstract

Electron-microscopic studies of the thymus of white laboratory rats in adverse environmental conditions established the ultrastructural features of stromal cells in different zones of the thymus. In the cortical zones, along with classical epithelioreticulocytes, dendritic and monocyte-like cells are predominant, interdigitating cells are localized mainly in the medullary zones. Macrophages and monocyte-like cells are frequent in the corticomedullary zones.
