Down to Sex? Boy and Girl Microglia Respond Differently
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.
TREM2, Microglia Dampen Dangerous Liaisons Between Aβ and Tau
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.
Dopaminergic Neurons Conjured from Astrocytes Restore Motion
At Keystone, researchers described how directly converting astrocytes into neurons within the mouse striatum restored neuron numbers in a model of PD.
Invading T Cells Quash Neurogenesis
Brains of old mice birth fewer neurons when T cells invade the subventricular zone. The immune cells spew inflammatory cytokines that snuff out neurogenesis.
Epilogue on Edonerpic: It Does Not Work in Alzheimer’s
Drug didn’t slow decline in a Phase 2 trial.
Gently Used: Can Recycled Microglia Receptors Prevent Plaque?
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.
Deleting CD33 Benefits Mice—If Their Microglia Express TREM2
TREM2 required for reduction of plaque load in CD33 knockouts.
In PD Model, α-Synuclein Spreads from Intestine to Brain
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.

Microglia Control Synapse Number in Multiple Disease States
Research presented at SfN strengthens the case that microglia gorge on synapses in some neurodegenerative and neurodevelopmental disorders.
