Astrocytes Restrict Access to Amyloid-β Plaques in the Aging Brain – Fight Aging!

[ad_1] Astrocytes Restrict Access to Amyloid-β Plaques in the Aging Brain Astrocytes react to the presence of extracellular amyloid-β aggregates in the aging brain by becoming more inflammatory and clustering around the aggregates of misfolded proteins. Researchers here show that this activity crowds out the microglia responsible for ingesting … Read more

Cellular Senescence in the Aging Brain, a Contributing Cause of Cognitive Decline – Fight Aging!

[ad_1] Senescent cells are created throughout the body at all stages of life, largely when somatic cells reach the Hayflick limit on replication. Senescent cells cease replication and begin to energetically produce pro-growth, pro-inflammatory factors, attracting the attention of the immune system and otherwise changing the behavior of surrounding … Read more
