For the last several years, Dr. José Pedro Castro, a Gladyshev Lab alumnus, who is now Assistant Researcher and Project Principal Investigator at the Institute for Research and Innovation in Health at the University of Porto, has been studying inflammation and its crucial role in aging and disease. Earlier this month, he received the Rising...

A new study suggests that aging or Parkinson’s-triggering mutations create inflammation in peripheral tissues, and then circulating extracellular vesicles spread it to the brain, which might contribute to the disease [1]. Brain on fire Nature made the brain remarkably well-protected, including from the elements by the skull and from pathogens by the blood-brain barrier (BBB)....

Researchers have found that bound pieces of RNA and DNA in the cytoplasm of senescent cells encourage these cells to secrete inflammatory factors. When transcription gets sticky As part of the transcription process that produces necessary proteins, RNA must chemically interact with DNA. When it binds to DNA and integrates itself into the genome, it...

Dr. Junyue Cao is a professor at the Rockefeller University, and his lab develops ultra-high-throughput single-cell technologies and applies them to the biology of aging. In a recent paper published in Science, his team used a technique called EasySci-ATAC to profile chromatin accessibility in about seven million cells from 21 mouse tissues across three ages,...

An investigation into the aging immune system identified age-related changes, including sex-dependent differences, in immune cell subpopulations and gene expression. In general, females showed greater age-related changes than males, including greater changes in autoimmune gene expression [1]. Cell-by-cell analysis Aging results in changes to the function and composition of immune cells, collectively referred to as...

A paper in Cell Genomics has described how age-related systemic inflammation (inflammaging) is related to epigenetic aging as measured by four established clocks. Tying together two well-known aspects of aging Chronic InflammationChronic inflammation refers to a persistent, low-grade buzz of immune activity that settles into the body without the drama of an infection or obvious...
