Tissue-resident macrophages (TRMs) are involved in the surveillance and maintenance of tissue homeostasis, yet their dysfunction is a hallmark of human diseases. Although mouse TRMs arise from sequential migrations of yolk sac progenitors, limited access to human embryonic tissue has hindered the study of the origin of...

Tau pathology closely tracks neuronal loss in Alzheimer's disease, but how phosphorylated tau becomes lethal has remained unclear. Chen et al. identify a dual-hit mechanism: glucose hypometabolism removes a protective A20-mediated brake on necroptosis while phosphorylated tau scaffolds RIPK1 activation, driving tau-ass...
A chimeric model of AD is generated by transplanting isogenic APOE3 or APOE4 human induced pluripotent stem cell-derived astrocyte progenitors into neonatal AD mice and highlighting a role for human astrocytes and APOE-dependent astrocyte functions in modulating AD-related pathology.

It is found that astrocytic cytosolic calcium activity is suppressed prior to amyloid plaque deposition and is accompanied by reduced lysosomal acidification in vivo, identifying lysosomal failure as an initiating event in astrocyte dysfunction in AD.
