Our experiments demonstrated that treatment with GB or GB-biotin reduced mitochondrial injury, restored mitochondrial membrane potential, and decreased cell apoptosis in a concentration-dependent manner.

Herpesvirus Antibodies Are Correlated With Greater Expression of p16 in the T Cells of Humans.

Background: There is an increasing awareness that aging of the immune system, or immunosenescence, is a key biological process underlying many of the hallmark diseases of aging and age-related decline broadly. While immunosenescence can be in part due to normal age-related changes in the immune system, emerging evidence posits that viral infections may be biological stressors of the immune system that accelerate the pace of immunosenescence.

Methods: We used a convenience sample of 42 individuals aged 65 years and older to examine correlations between antiviral immunoglobulin G (IgG) levels for 4 human herpesviruses (cytomegalovirus [CMV], herpes simplex virus [types 1 and 2], and Epstein-Barr virus) and multiple indicators of T-cell immunosenescence.

Girard Derivatization-Based Enrichment Strategy for Profiling the Carbonyl Submetabolome in Biological Samples.

Numerous bioactive compounds containing carbonyl groups, including aldehydes and ketones, are widely acknowledged as potential biomarkers for several diseases and are implicated in the development of metabolic disorders. However, the detection of carbonyl metabolites is hindered by challenges, such as poor ionization efficiency, low biological concentration, instability, and complexity of the sample matrix. To overcome these limitations, we developed a Girard derivatization-based enrichment (GDBE) strategy for capturing and comprehensively profiling carbonyl metabolites in biological samples.

Insights into the transcriptomic heterogeneity of brain endothelial cells in normal aging and Alzheimer's disease.

Drug development for Alzheimer's disease Is extremely challenging, as demonstrated by the repeated failures of amyloid-β-targeted therapeutics and the controversies surrounding the amyloid-β cascade hypothesis. More recently, advances in the development of Lecanemab, an anti-amyloid-β monoclonal antibody, have shown positive results in reducing brain A burden and slowing cognitive decline in patients with early- stage Alzheimer's disease in the Phase III clinical trial (Clarity Alzheimer's disease). Despite these promising results, side effects such as amyloid-related imaging abnormalities (ARIA) may limit its usage.
