Overview of Gene Research
Itgb2, also known as integrin beta 2, is a crucial coordinator of extracellular and intracellular signaling. Integrins play important roles in various biological processes such as cell adhesion, migration, and signal transduction. Itgb2 is involved in pathways like PI3K/AKT/mTOR [1]. It is of great biological importance as it is known to be important for host defense [1]. Genetic models, like KO/CKO mouse models, could potentially be valuable for studying its functions.

In oral squamous cell carcinoma (OSCC), CAFs with higher Itgb2 expression promote OSCC proliferation by regulating PI3K/AKT/mTOR pathways to enhance glycolysis activity, and the lactate derived from these CAFs is metabolized in OSCC cells to produce ATP via mitochondrial oxidative phosphorylation [1]. In non-small cell lung cancer, lncRNA Itgb2-AS1, which is positively correlated with Itgb2, promotes cisplatin resistance by inhibiting ferroptosis via activating the FOSL2/NAMPT axis [2]. In severe acute pancreatitis-related acute lung injury, extracellular vesicles overexpressing Itgb2 can attenuate pulmonary inflammation and endothelial cell barrier disruption [3]. In cerebral ischemia-reperfusion injury, Itgb2+ microglia subclusters have time-specific functions in energy metabolism, cell cycle, angiogenesis, neuronal myelin formation, and repair [4]. In glioblastoma, activation of Itgb2 in microglia promotes the mesenchymal transition of GBM cells through JAK1/STAT3/IL-6 signaling feedback [5]. In diabetic nephropathy, Itgb2 is up-regulated and may serve as a diagnostic marker [6]. In inflammatory bowel disease, Itgb2 is up-regulated in the IBD mouse model, and its suppression alleviates inflammation; it may also be a diagnostic marker for IBD-associated CRC [7]. In BAP1-mutated uveal melanoma, the Itgb2-ICAM1 axis promotes liver metastasis by preserving hypoxia-and ECM-related signatures [8]. In gliomas, Itgb2 is elevated in higher malignancy cases, predicts poor prognosis, and patients with high Itgb2 expression have a better immunotherapy response [9]. In premature infants with necrotizing enterocolitis, there is a trend of increased ITGB2 variants proportionately with increasing NEC severity in extremely low birthweight infants [10].

In conclusion, Itgb2 is essential for coordinating extracellular and intracellular signaling, playing important roles in multiple disease conditions including cancer, inflammation-related diseases, and ischemia-reperfusion injury. Studies using various models, though not all explicitly KO/CKO mouse models, have revealed its diverse functions in these disease areas, helping to understand disease mechanisms and potentially providing new therapeutic targets.
