Conclusions Implanted Hair Follicle Cells Produce Remodeling of Scar Tissue Assessment of Somatic Mosaicism as a Biomarker of Aging The Gut Microbiome of Centenarians https://www.fightaging.org/archives/2023/01/the-gut-microbiome-of-centenarians/ The state of the gut microbiome is arguably as influential on health as exercise. Various microbial species present in the gut produce beneficial metabolites, such as butyrate, or harmful metabolites, such as isoamylamine, or can provoke chronic inflammation in a variety of ways. An individual can have a better or worse microbiome, assessing these and other fu...

Differential Antibody Response to Inactivated COVID-19 Vaccines in Healthy Subjects
Front Cell Infect Microbiol. 2021 Dec 16;11:791660. doi: 10.3389/fcimb.2021.791660. eCollection 2021.ABSTRACTThe appearance and magnitude of the immune response and the related factors correlated with SARS-CoV-2 vaccination need to be defined. Here, we enrolled a prospective cohort of 52 participants who received two doses of inactivated vaccines (BBIBP-CorV). Their serial plasma samples (n = 260) over 2 months were collected at five timepoints. We measured antibody responses (NAb, S-IgG and S-IgM) and routine blood parameter. NAb seroconversion occurred in 90.7% of vaccinated individuals and four typical NAb kinetic curve...

This study was the first to demonstrate a causal relationship between glial senescence and neurodegeneration. In this study, accumulations of senescent astrocytes and microglia were found in tau-associated neurodegenerative disease model mice. Elimination of these senescent cells via a genetic approach can reduce tau deposition and prevent the degeneration of cortical and hippocampal neurons. Most recently, it was shown that clearance of senescent oligodendrocyte progenitor cells in AD model mice with senolytic agents could lessen the Aβ plaque load, reduce neuroinflammation, and ameliorate cognitive deficits. This...

This study elucidates the potential to use mitochondria from different donors (PAMM) to treat UVR stress and possibly other types of damage or metabolic malfunctions in cells, resulting in not only in-vitro but also ex-vivo applications. Gene Therapy in Mice Alters the Balance of Macrophage Phenotypes to Slow Atherosclerosis Progression https://www.fightaging.org/archives/2019/07/gene-therapy-in-mice-alters-the-balance-of-macrophage-phenotypes-to-slow-atherosclerosis-progression/ Atherosclerosis causes a sizable fraction of all deaths in our species. It is the generation of fatty deposits in blood vessel...
