- Cutaneous lymphocyte-associated antigen(CLA) is a special adhesion molecule expressed on the surface of T lymphocytes and also a skin-homing receptor on memory T lymphocytes. 皮肤淋巴细胞相关抗原是T淋巴细胞表面表达的一种特异的黏附分子,是记忆T淋巴细胞的皮肤归巢受体。
- Objective:To investigate the distribution of 5-hydroxy tryptamine(5-HT) in rat thymus and its immunological implication in the developm e nt of T lymphocytes. 目的:探讨大鼠胸腺内5-羟色胺(5-HT)免疫反应性的分布及与T细胞发育的关系。
