[Are HBsAg positive viral hepatitis and its fate caused by the genetically determined immune response to the infection?].

The Authors, after a review of the latest researches about the immunopathogenesis of hepatitis B, propose a new hypothesis that points out the importance of antigen-specific suppressor T-lymphocyte activity for the evolution of hepatitis-B-virus infection. It is possible to verify this working hypothesis by employing a modified migration inhibition factor test, using preparations of isolated T-lymphocytes.
