[Role of antigen-nonspecific suppressors occurring in stress in the pathogenesis of Langat virus infection in mice].

Stress factors of different nature activate antigen-nonspecific suppressors inhibiting different mechanisms of immune response in mice. The adoptive transfer of the population of immunocompetent cells containing stress-induced suppressors to mice infected with Langat virus has been found to lead to the activation of asymptomatic infection. The data obtained in this investigation indicate that the above-mentioned mechanism of the development of antigen-nonspecific immune deficiency is of importance in the pathogenesis of viral infections in man and it explains the onset of diseases (or their aggravation) under the conditions of stress.
