十多年来国内外许多学者对淋巴细胞内的乳酸脱氨酶(LDH)同工酶进行了研究,发现正常人T、B淋巴细胞的LDH同工酶谱型不完全相同。在T细胞中,T_γ细胞和T_μ细胞、胸腺皮质细胞和髓质细胞的LDH同工酶谱型也不一致。即使是同一细胞群,由于分化成熟程度不一,LDH同工酶谱型也各异,可作为区分淋巴细胞亚群的标志和细胞分化程度的参考。 Over the past decade, many scholars at home and abroad have studied the lactate deaminase (LDH) isoenzymes in lymphocytes and found that the LDH isoenzyme patterns of normal human T and B lymphocytes are not identical. In T cells, the LDH isoenzyme patterns of T_γ cells and T_μ cells, thymic cortical cells, and medulla cells are also inconsistent. Even in the same cell population, the LDH isoenzyme pattern is different due to the different degree of differentiation and maturation, which can be used as a reference for distinguishing lymphocyte subsets and the degree of cell differentiation.
