Abstract:
Changes in dehydrogenase activity of some continuous cell lines were studied during the response to acute infection in vitro with HIV-1 variants having different biological features. Soon after infection, the dehydrogenase activity of infected cells increased, and this increase was greater and more prolonged with the HIV-1 r/h variant than with the HIV-1 s/l variant. Later stages showed decreased dehydrogenase activity of HIV-1-infected cells compared to the noninfected control; this is a manifestation of the cytodestructive effect of the virus. The changes increased monotonously (but not in direct proportion) with an increase in the infecting dose.
