As the immune system ages, it enters a state of chronic, low-grade inflammation called ‘inflammaging’. In the brain, inflammaging is especially damaging. Immune cells that normally clear toxic amyloid-beta, a protein that can clump together to form the plaques characteristic of Alzheimer’s disease, instead become dysfunctional, fuelling the neuroinflammation that drives the disease. So a…

When daytime photons, which are rich in blue light, enter the retina, they ‘activate’ cells containing melanopsin. | Photo Credit: Ron Lach/Pexels — Sahitya Agrawal, Raxaul A: The brain’s biological clock is a network of genes and proteins whose concentrations rise and fall in a roughly daily cycle. There is a cluster of neurons in…

The findings of a new study imply that genome-wide association studies — an increasingly popular kind of study that looks for the genetic variants linked to diseases — may be missing a significant fraction of heritable variation because that variation is not in the sequence Source link

Using ‘genome language models’, they generated thousands of…
