| Abstract: | The sera of patients with lymphadenopathies (children, suffering from primary immune deficiencies) and AIDS were analysed for the presence of antibodies against D-type retroviruses by means of radioimmunoprecipitation (RIP) and Western blotting. It was established that these sera contain the antibodies derived against p27, the major structural protein of type-D retroviruses, in a considerable percentage (12/80 for lymphadenopathy (LAP) patients and 9/12 for AIDS patients). Some serum samples reacted in RIP with Pr78gag, the precursor of gag-coded proteins of these viruses. The results obtained for AIDS patients are in contrast with those reported by other research groups. Nevertheless, it seems highly probable that D-type retroviruses are truly associated with human immunodeficiencies, as has been shown for simian ones. |
