Abstract

Aging is associated with enumerative and functional changes of peripheral innate immune cells, notably myeloid cells (ex., monocytes/macrophages and neutrophils). Peripheral myeloid cells routinely infiltrate the brain, particularly at the brain borders, influencing cognition, mood, and stress responses.

Research summary

The paper claims that the interplay between peripheral and CNS myeloid cells during aging influences late-life depression and Alzheimer's disease. This research is relevant as it explores the role of immune cell changes in aging, which could contribute to understanding the underlying mechanisms of age-related diseases.
