[Dysregulation of cytokine production by mononuclear cells of peripheral blood in persistent infection with a virus of tick-borne encephalitis].

: Tick-borne encephalitis is accompanied by dysregulation of cytokine production of mononuclear leucocytes of peripheral blood. The changes of production of IFN-r by mononuclear leucocytes of peripheral blood positively correlated with a degree of activity of pathological process and intensity of clinical symptoms of neuroninfection. On the contrary, secretion of IL-12 mononuclears directly correlated with virus persistence in the organism and does not depend on clinical presentation of the disease.
