Lymphadenopathy-associated retrovirus adapted to continuous lymphoblastoid-B cell lines capable of continuously producing said retrovirus, and process for preparing the cell lines

摘要

The invention provides continuous and permanent cell lines characterized by their ability to produce a continuous retrovirus having the essential antigenic characteristics of the virus considered responsible for the immunodéfricience syndrome (AIDS). These lines are costituées B lymphoblastoid cells infectable including LAV retrovirus, previously adapted to B lymphocytes, in the presence of lymphocytes T.; The invention also concerns the LAV adapted to the aforementioned continuous and permanent lines. Extracts are used in diagnostic tests in vitro AIDS.
