In this study, titled “Single-cell transcriptomics reveal intrinsic and systemic T cell aging in COVID-19 and HIV” and published in Volume 18 of Aging-US, researchers used single-cell RNA sequencing to analyze aging-related changes in human T cells.

Aging reshapes the immune system in two fundamental ways: it alters the proportions of different immune cell types circulating in the blood, and it induces molecular changes within each individual cell.
A new study published recently as the cover of Aging Volume 17, Issue 6, describes a new method to estimate how fast the brain is aging. By analyzing lipids, or fat molecules, in brain tissue, researchers from the National University of Singapore and Hanze University of Applied Sciences created a biological “clock” called DoliClock.
This study introduces DoliClock, a lipid-based biological aging clock designed to predict the age of the prefrontal cortex using post-mortem lipidomic data. Significant age acceleration was observed in autism, schizophrenia, and Down syndrome.
