摘　要：

细胞黏附分子1 (intercellular cell adhesion molecule-1, ICAM-1) 介导细胞黏附并调控炎症应答，也是病原体入侵的重要跨膜蛋白。其作为病毒受体介导病毒的吸附、内吞运输及脱壳等过程，促进小核糖核酸病毒及流感嗜血杆菌等病原体的感染；ICAM-1 还通过与LFA-1 (lymphocyte function associated antigen-1, LFA-1) 结合形成病毒学突触增强病毒传播效率。此外，ICAM-1 可介导肿瘤细胞的黏附浸润及炎性微环境的形成。研究表明，抗体偶联药物、受体竞争性结合等靶向ICAM-1 的干预策略可系统性阻断病毒吸附、抑制病毒的生命周期。本文综述了ICAM-1 在促进多种病原体增殖与传播过程中的功能机制，为深入探索病毒生物学特性以及新型靶向抗病毒药物的研发提供参考依据。

Abstract:

Cell adhesion molecule-1 (ICAM-1) is a transmembrane protein, mediating cell adhesion and
inflammatory response. It is a critical host protein for pathogen invasion, involving in viral adsorption, endocytosis, and uncoating through acting as viral receptor to promote the infection of multiple pathogens, such as picornaviruses and haemophilus influenzae. ICAM-1 also enhances viral transmission efficiency by binding to lymphocyte function associated antigen-1 (LFA-1) to form virological synapses. Moreover, ICAM-1 can mediate the adhesion invasion of tumor cells and formation of inflammatory microenvironment during tumorigenesis. Research indicates that targeted interventions against ICAM-1, including antibody-drug conjugates and receptor-competitive binding agents, systematically block the adsorption of virus and inhibit the life cycle of viruses. Here, we review the functional mechanisms of ICAM-1 in promoting the proliferation and transmission of multiple pathogens to provide insights on further revealing virus biological characteristics and the development of novel antiviral drugs.
