Exploring the Expression Profiles of Serum Inflammatory Proteins and Potential Antiaging Targets in Chinese Long-Living People.

Chronic inflammation (inflammaging) is one of the important reasons for the development of age-related diseases and aging. Carrying out aging research and mining inflammatory markers can develop antiaging intervention targets, thus promoting healthy aging. By comparing the levels of inflammatory proteome in the serum of Chinese long-living people over 90 years and elderly aged 60∼79 which was detected by Olink platform, this study found that some pro-inflammatory or pro-aging proteins increased significantly in the long-living people, such as c-x-c motif chemokine ligand 9, accompanied by a significant increase in the levels of several anti-inflammatory or antiaging proteins, including fibroblast growth factor 19 and fibroblast growth factor 23, which confirmed that compared with elderly people, pro-inflammatory and anti-inflammatory (pro-aging and antiaging) tend to be balanced in long-living people, thus reducing the risk of age-related diseases and prolonging the lifespan of the elderly.

Structural and functional insights of sortases and their interactions with antivirulence compounds.

Sortase proteins play a crucial role as integral membrane proteins in anchoring bacterial surface proteins by recognizing them through a Cell-Wall Sorting (CWS) motif and cleaving them at specific sites before initiating pilus assembly. Both sortases and their substrate proteins are major virulence factors in numerous Gram-positive pathogens, making them attractive targets for antimicrobial intervention. Recognizing the significance of virulence proteins, a comprehensive exploration of their structural and functional characteristics is essential to enhance our understanding of pilus assembly in diverse Gram-positive bacteria.
