Two groups create mice for imaging and manipulation of microglia, leaving related cells untouched. The trick? Piggybacking on Tmem119 expression.
Through an endocytic process called LANDO, microglia clear β-amyloid and route their used Aβ receptors, including TREM2, back to the plasma membrane. Without it, aggregates pile up outside and form plaques.
At a joint Keystone symposia, researchers reported how microglia, via TREM2, compress plaques and rein in the pathogenic distortion of neurites into swollen stubs. Without TREM2, these damaged neuronal processes served as fertile ground for tau propagation.
TREM2, Microglia Dampen Dangerous Liaisons Between Aβ and Tau Down to Sex? Boy and Girl Microglia Respond Differently Dopaminergic Neurons Conjured from Astrocytes Restore Motion In PD Model, α-Synuclein Spreads from Intestine to Brain Do Microglia Finish
Microglial responses to Alzheimer’s risk variants, and to tau pathology, appear to show a sex difference. Microglia in male versus female mice use different biological mechanisms to maintain homeostasis.
At Keystone, researchers described how directly converting astrocytes into neurons within the mouse striatum restored neuron numbers in a model of PD.
Brains of old mice birth fewer neurons when T cells invade the subventricular zone. The immune cells spew inflammatory cytokines that snuff out neurogenesis.
Drug didn’t slow decline in a Phase 2 trial.
TREM2 required for reduction of plaque load in CD33 knockouts.
Injecting α-synuclein fibrils into mouse gut sparked the proteopathic spread of misfolded α-synuclein into the brain, where the aggregates killed dopaminergic neurons and caused motor problems.
At Quebec conference, researchers considered multiple aspects of herpesvirus biology that may come in to play in AD.
Going Viral: Alzheimer’s Research at Herpes Conference Herpesvirus: Trigger for Many Brain Pathologies? In light of recent work implicating human herpesviruses in AD, virologists invited Alzheimer’s researchers to join them at the 11th International Confe
A U.K. research program developed guidelines for clinical practice. In preliminary studies, it boosted diagnosis and improved patient care.
