Abstract

Early thymus-derived lymphocytes bearing the T gamma gene product in association with the CD3(T3) complex have recently been described. We report a unique case of human acute lymphoblastic leukemia with a CD2+, CD3+, CD4-, CD5+, CD7+, CD8-, WT31- phenotype. These cells were found to have T gamma gene rearrangement and T gamma transcripts in absence of T alpha or T beta rearrangement or transcripts. Immunoprecipitation studies with anti-CD3 antibodies showed a 43-kD protein associated with T3; this 43-kD protein is also precipitated with antiserum raised against synthetic peptides representing the constant region of the putative T gamma protein.

摘要

最近已描述了早期胸腺来源的淋巴细胞带有与CD3(T3)复合物相关的Tγ基因产物。我们报告了1例具有CD2 +、CD3 +、CD4 -、CD5 +、CD7 +、CD8 -、WT31 - 表型的人类急性淋巴细胞白血病的独特病例。发现这些细胞有Tγ基因重排和Tγ转录本,而不存在Tα或Tβ重排或转录本。用抗CD3抗体进行的免疫沉淀研究显示有一种与T3相关的43-kD蛋白;这种43-kD蛋白也能用针对代表推定的Tγ蛋白恒定区的合成肽产生的抗血清沉淀出来。
