CD2 (E receptor, LFA-3 receptor) and E2 molecules (Bernard, 1988) on human T lymphocytes, CD58 (LFA-3, lymphocyte function associated antigen 3) on human erythrocytes and S14,S42,S110-220 molecules (Bernard, 1987) of sheep erythrocytes are involved in rosette formation of human T lymphocytes with human or sheep erythrocytes. Rosette formation of human and macaque pan-T lymphocytes with tree shrew (Tupaia belangeri) red blood cells (TRBC) (TRBC rosette) has shown different physicochemical properties from that of rosette formation with sheep red blood cells (E rosette) (Ben, 1985). CD2, CD3/TCR complex, CD5, CD6, and CD7 are not involved in TRBC rosette formation (Zheng, 1990). In order to know whether E2, LFA-3,S14,S42 and S110-220 molecules are involved in TRBC rosette formation or human and macaque T lymphocytes, rosette inhibition and antigenic modulation or co-modulation were performed with relevant monoclonal antibodies (McAbs), and hemolytic assay and slide agglutination were also conducted. TRBC rosette formation of human and rhesus monkey PBL was not blocked by E2 McAb (inhibition rate 2.8% and 2.1%, respectively). In contrast, human E rosette formation was obviously blocked at inhibition rate of 49.8% and macaque E rosette formation was slightly inhibited (13.3%). The modulation or co-modulation of E2 molecule with E2 McAb did not affect human TRBC rosette formation. Similar results were shown in rosette formation inhibition of Jurkat cells.(ABSTRACT TRUNCATED AT 250 WORDS)
