Interplay between Peripheral and Central Nervous System Myeloid Cells during Aging: Impact for Lade-Life Depression and Alzheimer’s Disease

The cumulative impact of these alterations undermines neuroprotection and facilitates age-related neuropsychiatric conditions, including neurodegenerative diseases and late-life depression. The identification of pro-aging circulating factors and cells could pave the way for new therapeutic strategies aimed at mitigating cognitive decline and improving mood. Targeting myeloid cell metabolism or inflammatory signaling pathways emerges as a promising strategy to mitigate aging-associated neuropsychiatric syndromes.
