Researchers from Chongqing Medical University discovered that excessive fibrin deposition drives chronic gum inflammation in diabetes by disrupting immune-epithelial crosstalk. By utilizing an engineered peptide (377P) to block fibrin-macrophage interactions, the team successfully suppressed inflammation, restored the mucosal barrier, and promoted alveolar bone healing in diabetic mice. This study identifies fibrin as a druggable target for diabetic periodontitis and potentially other systemic diabetic complications.

A meta-analysis of 21 Japanese case-control studies re-evaluated the association between APOE-e4 homozygosity and Alzheimer’s disease risk. While a landmark 1997 study estimated a more than 30-fold increase in risk, the present analysis indicates a substantially lower but still strong effect of approximately 12–15-fold. These findings provide updated risk estimates for Japanese populations and establish a more robust foundation for genetic risk assessment and future preventive strategies.

Most research studies analyzing the effects of species loss on the health and productivity of grasslands do not reflect the conditions of mature or natural grasslands. In this study, a research team analyzed how changing the order of species removal in a grassland community changed the pathways linking species loss to community stability, which is more reflective of species loss scenarios in nature.
