Michal Schwartz on With Age, Macrophages Chew up the Blood-CSF Barrier

COMMENT This paper by Chen and colleagues provides new insight into the delicate balance between immune cells and the brain, particularly at the barriers that serve as physiological interfaces between these two systems. Specifically, the authors focus on how the

Charles Stromeyer on Can Autoimmunity Spark Alzheimer’s Disease?

COMMENT Autoimmune disorders are more prevalent in females versus males, and a molecular clue is that Xist long noncoding RNA (lncRNA) ribonucleoproteins are a promoter of sex-biased autoimmunity (Dou et al., 2024), and Xist appears in the cytoplasm of AD (Sen an
