Summary: miR-27b is highly expressed in endothelial cells and plays a crucial role in regulating inflammatory pathways, cell cycle, apoptosis, and mitochondrial oxidative imbalances. miR-27b mimic can counteract the cytotoxicity and inflammation caused by TNF-alpha, as well as restore mitochondrial function. Mechanistically, miR-27b targets FOXO1 to achieve its functions.

Summary: This study investigates the role of thrombospondin (TSP)-1 in regulating leukocyte recruitment and VCAM-1 expression in mouse models of uveitis. The results show that TSP-1 deficiency can reduce retinal leukocyte adhesion in LPS-mediated acute uveitis, while TSP-1-derived CD47-binding peptide can reduce the clinical disease course and retinal leukocyte adhesion in chronic uveitis.

Summary: IL-6 affects tissue protection/repair and inflammatory properties of vascular endothelial cells (ECs). Classic signaling and trans-signaling have distinct effects on ECs, with trans-signaling inducing more inflammatory responses and significant impact on EC survival and inflammatory activation.

Summary: The bidirectional interaction between adipocytes and adipose tissue immune cells is crucial for regulating adipose function, inflammation, and insulin responsiveness. Obesity reduces cAMP-driven IL-6 secretion from adipocytes, but restoring their catecholamine sensitivity can stimulate IL-6 secretion and activate macrophages to promote an anti-inflammatory gene expression pattern.

Summary: Netrin-4 plays a crucial role in endothelial cell function and is essential for maintaining endothelial cell health. Reduced levels of netrin-4 can lead to abnormal endothelial cell function, including senescence, inflammation, and impaired barrier function. Additionally, netrin-4 also enhances endothelial cell adherence to the extracellular matrix, exhibiting a pro-survival effect on endothelial cells.

Summary: Endothelial dysfunction is associated with vascular disease, and aPC/PAR1 signaling promotes Rac1 activation and barrier protection via beta-arr2. The cytoprotective responses of aPC/PAR1 involve various signaling pathways, including the beta-arr2-mediated SphK1-S1PR1-Akt signaling axis.

Summary: The study show that basophils play a crucial role in promoting tissue repair after myocardial infarction by increasing levels of IL-4 and IL-13 in the heart. Depletion of basophils leads to an increase in inflammatory response, scar thinning, and deterioration of cardiac function post-MI.

Summary: This study reveals that influenza infection facilitates a broader antibody response by unmasking haemagglutinin epitopes and signaling IL-4 in the germinal center, shedding light on the differences in antibody responses induced by vaccination versus infection.

Summary: This study aimed to investigate the inflammatory and regulatory cytokines in the milk of dairy cows with subclinical and clinical mastitis. The results showed that IL-1 alpha, IL-4, and IL-17A drive the inflammatory responses in mastitis cases. Furthermore, the host defense response in mastitis is characterized by the continuation or resolution of the initial inflammation.

Summary: This study found that irisin effectively reduced free radical production by macrophages and altered the kinetics of key factors in the Nrf2/HO-1/HMGB1 pathway, leading to increased production of Nrf2 and HO-1 while significantly reducing HMGB1 release.

Summary: The IL-4/IL-13 signaling axis plays a crucial role in the development of lower urinary tract symptoms. IL-4 and IL-13 promote the activation of prostate fibroblasts and the secretion of extracellular matrix, leading to fibrosis. These findings have important clinical implications for the treatment of lower urinary tract symptoms.

Summary: Type 2 immunity plays a crucial role in protecting against parasites and responding to allergens, as well as maintaining tissue integrity and promoting wound repair. IL-4 and IL-13, key type 2 cytokines, are involved in suppressing the initial inflammatory response to injury and modulating extracellular matrix changes for effective repair. However, the exact contribution of IL-4R alpha signaling in wound repair is still not fully understood due to redundancy and other signaling pathways.

Summary: Pulmonary arterial hypertension (PAH) is a complex disorder where cytokines play a crucial role in deregulation of the immune system. This study found that PAH patients have abnormal immune function with decreased percentages of immune cell subpopulations and changes in cytokine concentration. Furthermore, significant differences were observed between PAH subtypes and immunological parameters, suggesting the important role of the immune system in the pathogenesis of PAH.
