Human T-cell leukemia virus-associated membrane antigens: identity of the major antigens recognized after virus infection. 1984

T H Lee, and J E Coligan, and T Homma, and M F McLane, and N Tachibana, and M Essex

Specific antibodies to cell membrane antigens found on human T-cell leukemia virus (HTLV)-infected cells have been detected in Japanese patients with adult T-cell leukemia/lymphoma and in asymptomatic carriers, using a live cell-membrane immunofluorescence assay. Reactivity of the positive antisera was analyzed using radioimmunoprecipitation and NaDodSO4/PAGE with the HTLV-infected tumor cell line Hut 102 (clone B2). The major cell-associated antigens identified include two glycoproteins of approximately equal to 61 and 45 kDa, which appear to be the most immunogenic species in exposed people, a nonglycosylated species of 42 kDa, and four additional species that contain gag gene-encoded antigens with sizes ranging from 19 to 55 kDa. The two glycoproteins ( gp61 and gp45 ) are encoded, at least in part, by the env gene of HTLV as evidenced by amino acid sequence analysis.

UI MeSH Term Description Entries
D007938 Leukemia A progressive, malignant disease of the blood-forming organs, characterized by distorted proliferation and development of leukocytes and their precursors in the blood and bone marrow. Leukemias were originally termed acute or chronic based on life expectancy but now are classified according to cellular maturity. Acute leukemias consist of predominately immature cells; chronic leukemias are composed of more mature cells.
