Article Abstract
Cerebral ischemia-reperfusion injury (CIRI) is a complex pathophysiological process faced by brain tissues after ischemic stroke treatment, which involves mechanisms of inflammatory response, oxidative stress and apoptosis, and severely affects treatment outcome. Lipocalin-2 (LCN2), an acute-phase protein, is significantly up-regulated after CIRI and promotes neural repair by enhancing astrocyte phagocytosis, but its over-activation may also trigger secondary inflammation and demyelination injury. LCN2 also plays a key role in neuroinflammation regulation by regulating the polarization state of astrocytes and the release of inflammatory factors, and may affect the integrity of the blood-brain barrier and a variety of pathologic injury processes. In view of the important role of LCN2 in CIRI, this article reviews the mechanism of LCN2, aiming to provide new ideas and methods for the treatment of ischemic stroke.

Brazilin, a natural homoisoflavonoid, is the primary bioactive ingredient derived from the bark and heartwood of L. It has been proven to exhibit multiple biological activities and therapeutic potential in chronic degenerative diseases, fibrotic disorders, inflammatory diseases, and cancers. However, whether it is involved in regulating the pathological process of acute kidney injury (AKI) is not fully understood.

N-(1,3-Dimethylbutyl)-N'-phenyl-p-phenylenediamine-quinone (6PPDQ), as a recently identified environmental toxicant, has garnered significant attention because of its widespread detection in ecosystems and human habitats. Emerging evidence highlights its potential detrimental effects on various organs. However, its carcinogenic potential remains poorly understood, particularly its role in clear cell renal cell carcinoma (ccRCC).

Background: Atopic dermatitis (AD) and ulcerative colitis (UC) are increasingly prevalent, and growing evidence suggests a potential link between them. However, the shared pathogenesis remains unclear. This study aims to identify the hub genes and immunological features underlying the connection between AD and UC.

Lymph node (LN) metastasis is a major determinant of poor prognosis in patients with gastric cancer (GC). Tumor-associated macrophages (TAMs) play a crucial role in promoting tumor metastasis and progression; however, the underlying mechanisms through which TAMs induce LN metastasis in GC remain poorly understood. This study demonstrates that low lipocalin-2 (LCN2) expression is associated with increased LN metastasis and shorter survival in GC.

Polytrauma is a critical global health concern characterized by immune dysregulation and a high risk of multiple organ dysfunction syndrome (MODS). Early molecular mechanisms linking trauma severity to organ injury are poorly understood. We used two rat blast-polytrauma models: a tourniquet-induced ischemia/reperfusion injury (tIRI) model and a non-ischemia/reperfusion injury (non-IRI) model.
