Cylocloxygenase-2 is an important mediator of arachidonic acid metabolism. Pan et al. recently identified a robust increase in the expression of cylocloxygenase-2 in proresolving macrophages (M2) during the repair phase of acute kidney injury. The investigators determined the prostaglandin E2 was produced in macrophages and demonstrated that signaling through the E-type prostanoid receptor 4 stimulated the expression of the anti-inflammatory transcription factor MafB. MafB was further shown to be essential for macrophage differentiation and mediation of the intrinsic repair response following experimental acute kidney injury.

This work aims to construct a functional titanium surface with spontaneous electrical stimulation for immune osteogenesis and antibacteria. A silver-calcium micro-galvanic cell was engineered on the titanium implant surface to spontaneously generate microcurrents for osteoimmunomodulation and bacteria killing, which provides a promising strategy for the design of a multifunctional electroactive titanium implant. Titanium-based implants are usually bioinert, which often leads to inflammation-induced loosening.

Myocarditis is a life-threatening inflammatory disorder that affects the cardiac muscle tissue. Current treatments merely regulate heart function but fail to tackle the root cause of inflammation. In myocarditis, the initial wave of inflammation is characterized by the presence of neutrophils.

Microglia, the central nervous system's resident macrophages, are critical for immune defense, protecting neurons during infection. Their role in postnatal brain development, particularly after injury, remains unclear. Nucling, a protein up-regulated during cardiac muscle differentiation, regulates NF-κB, influencing apoptosis and cell proliferation.

Objective: Atopic dermatitis (AD) is a common chronic inflammatory skin problem. Herein, we aimed to demonstrate the efficacy of matrine (MT) on AD and to reveal its mechanism.
Material And Methods: An AD model was induced topical administration of 1-fluoro-2,4-dinitorobenzene (DNFB).

Background: The cluster of differentiation 47 (CD47)-signal regulatory protein alpha (SIRPα) axis is a key regulator of innate immune surveillance, facilitating the neoplastic evasion of macrophage-mediated phagocytosis. Although this pathway has been implicated in tumor immune escape in multiple malignancies, its clinical and prognostic significance in esophageal squamous cell carcinoma (ESCC) remain to be fully elucidated.
Methods: We retrospectively analyzed 100 patients who underwent esophagectomy for resectable ESCC.
