CHANGING EXPRESSION OF SOME MOLECULES ON THE SURFACE OF HUMAN BLOOD T-LYMPHOCYTES UPON UV-IRRADIATION OF CELL SUSPENSIONS
Abstract. We have studied effects of UV irradiation (240-390 nm) at a dose range of 151 to 1359 J/m2 upon expression levels of different surface markers (CD2, CD11a, CD3, CD4, CD8) of human blood T lymphocytes by means of laser flow cytofluorimetry. It is revealed that UV-irradiation at the doses of...

| Sumario: | Abstract. We have studied effects of UV irradiation (240-390 nm) at a dose range of 151 to 1359 J/m2 upon expression levels of different surface markers (CD2, CD11a, CD3, CD4, CD8) of human blood T lymphocytes by means of laser flow cytofluorimetry. It is revealed that UV-irradiation at the doses of 151 to 906 J/m2 caused increased expression of CD3, CD4, CD8 membrane markers of the T-lymphocytes. Meanwhile, it was shown that expression levels of CD2 and CD11a adhesion molecules on T-lymphocytes after exposure to UVirradiation (151 to 906 J/m2) remained similar to those for intact cells. UV-irradiation at a dose of 1359 J/ m2 was shown to reduce expression of CD2, CD11a and CD3 markers, along with increased expression level of CD4 and CD8 co-receptor molecules at the T-lymphocytes. |
