Structural and functional state of human blood lymphocytes after exposure to UV light (240-390 nm) in doses of 151-1359 J/m2 was studied by methods of laser flow cytofluorometry, indirect immunofluorescence, and fluorescent probes. Using a combination of these methods, we have showed that UV light in the specified doses induced changes in the surface phenotype of T cells: stimulation or suppression of the expression of antigen-recognizing receptor complex molecules (CD3, CD4, and CD8 markers) and their redistribution on the surface of immunocompetent cells (capping effect) with the formation of receptor clusters of various types.
