Structural and functional characteristics of lymphocytes in chronic carriers of tick-borne encephalitis virus.

Study of the surface phenotype, structure of plasma membrane, and activity of DNA repair system in peripheral blood lymphocytes from patients with different clinical forms of tick-borne encephalitis associated with long persistence of the virus revealed a pronounced imbalance between lymphocyte subpopulations, increased microviscosity of the plasma membrane lipid phase, and decreased activity of the DNA repair system in lymphocytes.
