THE EXPRESSION LEVEL OF THE MOLECULES OF THE RECEPTOR COMPLEX CD95 AND CD8 HUMAN BLOOD LYMPHOCYTES UNDER CARBON MONOXIDE AND ULVTRAVIOLET LIGHT INFLUENCE
By means of enzymoiimmunoassay and flow cytofluorometry the effect of carbon monoxide and ultraviolet (UV)-light on the expression level of the receptor complex molecules (CD95 and CD8 markers) on the membranes of human blood lymphocytes has been studied. It was stated that the carbon monoxide causes decrease of CD95 receptors on the surface immune cells during (60  90 min). However, strengthening of this effect was registered in 24 hours. It is shown that UV-light in 453 and 755 J/m<sup>2</sup> doses provides the pro-apoptotic effect as related to the expression level of CD95 receptors of analyzed cells. After daily thermostating of modified lymphocytes, different receptiveness of CD8 molecules to carbon monoxide was revealed. Thus, in patients with initially higher levels of CD8 markers - decrease is registered, and in individuals with initially low - increase in this marker levels. The obtained data of blood lymphocytes receptor profile changes in the presence of low molecular ligand (CO) must be taken into account in the Ultraviolet Blood Irradiation-therapy in patients with different etiologies.
