Abstract
The present invention relates to a novel human immunodeficiency virus (HIV) capable of inducing lymphadenopathies (LAS) and acquired immune deficiency syndromes (AIDS) in patients which has been designated the lymphadenopathy associated virus strain MAL (LAVMAL). Although the overall genomic organization of LAVMAL is similar to other known HIV-1 isolates such as LAVBRU and HTLV-III, nevertheless, this virus also displays considerable genotypic and phenotypic diversity as compared to these isolates. A proviral molecular clone of the virus was obtained and characterized. The complete nucleotide sequence of this clone was ascertained and putative regulatory regions (e.g., U3, R, U5,), regulatory elements (e.g., the TATA box, AATAAA polyadenylation signal, primer binding site), and open reading frames (e.g., Gag, Pol, Env, Vif, Vpr, Tat, Rev, Nef) identified. Of particular interest are unique polypeptides derived from the viral envelope. The claimed invention is directed toward isolated LAVMAL Env polypeptides consisting of 5-150 amino acids wherein said peptides contain a LAVMAL-specific epitope. These peptides will prove useful, inter alia, as diagnostic reagents and in the generatio…
