Three monoclonal antibodies to human T cell lymphotropic virus type I (HTLVI) p19 internal core protein, designated as alpha HTLV-2, 3, and 4, have been developed. In indirect immunofluorescence (IF) assays, these antibodies reacted with acetone-fixed cytocentrifuge preparations of culture HTLVI-infected peripheral blood leukocyte (PBL) from a patient (SD) with Japanese adult T cell leukemia and with infected HUT-102 T cells but not with cultured normal PBL. Anti-p19 antibodies alpha HTLV-2, 3, and 4 all reacted with the same HTLVI p19 identified both by antibodies in HTLVI+ patient sera and by antisera raised against two synthetic peptides encoded by the p19 gag region of HTLVI. Partial proteolytic cleavage of p19 immunoprecipitates obtained with antibodies alpha HTLV-2, 3, and 4 produced a 17,000-dalton cleavage product, in agreement with the size of the fragment predicted from the nucleic acid sequence of the HTLVI p19 gag region. Antibodies alpha HTLV-3 and 4 reacted with HTLVI but not HTLVII proteins and were useful diagnostic probes in identifying HTLVI- but not HTLVII-infected lymphoid cells in immunofluorescence assays. In addition to reacting with HTLVI p19, antibodies 2 and 4 also cross-reacted with a wide variety of HTLV-uninfected normal and neoplastic cells and tissues. In addition, HTLVI+ patient sera contained antibodies that competed for binding to the antigenic site on p19 recognized by antibody 4. Thus, anti-p19 monoclonal antibodies alpha HTLV-2 and 4 reacted with a 19,000-dalton viral-encoded protein of HTLVI and cross-reacted with normal host tissues, while anti-p19 antibody alpha HTLV-3 was specific for HTLVI p19 core protein.
