Abstract

In 1985, rosette formation of human and macaque pan-T lymphocytes with tree shrew red blood cells (TRBC) (TRBC rosette) was first found by Ben K et al, showing different physico-chemical properties from that of rosette formation with sheep red blood cells (E-rosette). In order to approach the correlation between TRBC receptor, E receptor (CD2) and other differentiation antigens (CDs) on T lymphocytes, rosette inhibition assay and antigenic modulation or co-modulation were performed with monoclonal antibodies (McAbs) to CDs, and the distribution of TRBC receptor in other peripheral immunocytes, cell lines was also examined. TRBC rosette appeared in 88.8% of E rosette positive peripheral blood lymphocytes (E(+)-PBL) and in 4.16% of E(-)-PBL. TRBC receptor was also found on all T cell lines tested (CEM, H33 HJ-JA 1, Jurkat, MLA-144, Molt-3, Molt-4, Molt-4 clone 8, PEER) and some myeloid lines (U 937 and HL 60), but not on human granulocytes, B cell lines (Daudi, Raji and Reh) and myeloid line K 562. The modulation or co-modulation of CD 3, TCR, CD 5, CD 6 and CD 7 with McAbs OKT 3, T 108 (F 1), T 136 (F 101-15), T 149 (M-T 604) and T 152 (7 G 5) did not affect TRBC rosette formation of PBL. TRBC rosette of human and rhesus monkey PBL was not inhibited by T 11.1 McAb OKT 11 (CD 2 McAb), in contrast human and rhesus monkey E rosette formations were obviously blocked at inhibition rates of 77.9% and 49.3%, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)
