Abstract
Sickle cell disease (SCD) is a hereditary disorder characterized by vaso-occlusion, inflammation, and tissue damage. Intercellular adhesion molecule 1 (ICAM-1) plays a crucial role in the pathophysiology of SCD by promoting the adhesion of sickle cells to the endothelium, contributing to vaso-occlusion and tissue damage. The ICAM-1 gene encodes a glycoprotein that interacts with lymphocyte function-associated antigen 1 (LFA-1) and macrophage 1-antigen (Mac-1) receptors, perpetuating inflammation, and oxidative stress. The NF-κB signaling pathway regulates ICAM-1 expression, which is elevated in patients with SCD, leading to increased endothelial cell activation and damage. Targeting ICAM-1 and its interactions with sickle cells and the endothelium has emerged as a potential therapeutic strategy for managing SCD. This review highlights the complex interplay between ICAM-1, sickle cells, and the endothelium, and discusses the potential of ICAM-1-targeted therapies for mitigating VOC and improving the quality of life for patients with SCD.
