Overview of Gene Research
Itgal, also known as Integrin subunit alpha L, encodes an integrin component of LFA-1 and is a membrane receptor molecule widely expressed on leukocytes. It plays a key role in the interaction between white blood cells and other cells, and is involved in immune-related processes [1,2,3,5,6,7,8].
In various cancers, Itgal shows different expression patterns and associations. In non-small-cell lung cancer (NSCLC), its down-regulation in tumor tissues is associated with poor prognosis, and high Itgal expression is related to increased infiltration of CD8+ T cells, CD68+ macrophages, CD4+ T cells, and CD20+ B cells, as well as better outcomes in patients with immune checkpoint inhibitor therapy [1]. In acute myeloid leukemia, high Itgal expression is linked to poor prognosis, and it is associated with age, cytogenetic risk classifications, MDSCs, macrophages, and most immune checkpoint genes and cytokines [2]. In gastric cancer, Itgal expression is increased in cancer samples, related to poor survival, and connected with immunomodulators, chemokines, and infiltrating levels of multiple immune cell types [3]. In melanoma, it is investigated for its relationship with immune infiltration and prognosis [4]. In lung adenocarcinoma, high Itgal expression is an independent predictor of better prognosis, and it suppresses malignant progression [7]. In NSCLC, low Itgal expression is related to poorer prognosis and increased malignancy, and its co-expressed genes are associated with immune-related signaling pathways [8]. In murine low-grade glioma, Itgal/CD11A in glioma-associated microglia is critical for CX3CL1 receptor expression, CX3CL1-directed motility, and glioma mitogen production, and antibody-mediated CD11a inhibition reduces tumor growth in vivo [9].
In conclusion, Itgal is crucial in immune-cell interactions. Studies, especially those using in vivo models like the murine models in low-grade glioma research, have revealed its diverse roles in cancer development, prognosis, and immune-microenvironment regulation, providing potential directions for targeted anti-tumor strategies [9].
