AB Recently, HIV has been shown to be highly variable in patients; it is
capable of escaping, or even turning off, cytotoxic T-cell responses by
mutating T-cell epitopes. New antiviral drugs have revealed the enormous
turnover of C4+ T cells in infected patients, but have also shown how
efficiently HIV rapidly escapes such treatments. Although HIV is usually
considered to be cytopathic, this is not really known. The proposal that
AIDS pathogenesis reflects immunopathological consequences of anti-HIV
protective CD8+ T cells has to be seriously considered. Such a
pathogenesis is illustrated by CD8+ T cell mediated immunosuppression
during acute infection of mice with the non-cytopathic lymphocytic
choriomeningitis virus.
