The lymphocyte function-associated antigen-1 (LFA-1) (also known as CD11a/CD18 and αβ₂), is just one of many integrins in the human body, but its significance is derived from its exclusive presence in leukocytes. In this review, we summarize the studies relating LFA-1 and its major ligand ICAM-1 (or CD54) with cancer, through the function of lymphocytes and myeloid cells on tumor cells. We consider how LFA-1 mediates the interaction of leukocytes with tumors and the role of ICAM-1 in tumor dynamics, which can be independent of its interaction with LFA-1. We also offer a more detailed examination of the role of LFA-1 within B-cell chronic lymphocytic leukemia. Finally, we discuss the role that exosomes harboring LFA-1 play in tumor growth and metastasis.
淋巴细胞功能相关抗原-1(LFA-1)(也称为CD11a/CD18和αβ₂),只是人体众多整合素之一,但其重要性源于它仅存在于白细胞中。在本综述中,我们通过淋巴细胞和髓样细胞对肿瘤细胞的作用,总结了将LFA-1及其主要配体细胞间黏附分子-1(ICAM-1,即CD54)与癌症相关联的研究。我们思考LFA-1如何介导白细胞与肿瘤的相互作用以及ICAM-1在肿瘤动态变化中的作用,而这一作用可能独立于其与LFA-1的相互作用。我们还更详细地研究了LFA-1在B细胞慢性淋巴细胞白血病中的作用。最后,我们讨论携带LFA-1的外泌体在肿瘤生长和转移中所起的作用。
