Cortical neurons gain mutations at similar yearly rates across six species, leaving aged humans with uniquely high mutational burdens and transcriptomic dysregulation.
Clearing these peripheral myeloid cells remodeled brain macrophages and improved cognitive performance without requiring the engineered immune cells to enter the brain.
Loss of the cGAMP-degrading enzyme ENPP1 allows microglia-derived signaling molecules to trigger STING-dependent inflammation across multiple brain cell types.
The three-dimensional cell platform maintains biological aging markers while spontaneously developing hallmark pathologies of sporadic Alzheimer disease.
Researchers linked poor auditory nerve synchrony and myelin degradation to amplified communication difficulties in older humans, beyond standard hearing thresholds.
