Phospholipase C-γ2 acts downstream of TREM2 to rev up beneficial inflammation, phagocytosis, and cell survival.
This neuronal protein regulates the complement cascade in the developing brain. Could it do the same in aging or neurodegenerative disease?
Carriers accumulate fewer tangles than noncarriers for a given amount of amyloid, explaining how the gene variant may lower a person’s Alzheimer’s risk.
In the mouse retina, these tender threads connect pericytes on nearby capillaries. They enable cells to coordinate constriction and dilation of blood vessels in response to neuronal activity.
Without the WD domain of Atg16L1, required for a newly discovered type of endocytosis, old mice develop hallmark pathologies of AD.
Dendritic tau suppresses production of nitric oxide, which prevents blood vessels from dilating in response to neural activity.
In the Alzheimer’s brain, too, plaques trigger a coordinated inflammatory response from microglia and astrocytes. A preprint paper had shown the same for mice.
Three studies agree that TMEM106b/progranulin double knockouts develop more extreme lysosomal dysfunction, inflammation, and motor deficits than PGRN KOs.
The designer chimera stabilizes synapses in various mouse models of neurodegenerative disease.
TRP cation channels combine with extrasynaptic NMDA glutamate receptors to set off mitochondrial meltdown and cell death. Blocking the interaction stops excitotoxicity.
This early marker distinguishes Alzheimer’s from controls and other neurodegenerative diseases more accurately than other biomarkers.
In large population datasets, people who had been vaccinated against influenza or pneumonia appeared less likely to develop AD.
Comprising mostly Aβ40, these large plaques are shot through with strange tubular structures and BBB markers. They are common in early onset AD.
Expert panel concludes there’s little risk based on current evidence.
AMX0035, a mix of sodium phenylbutyrate and taurursodiol, slowed functional decline over six months by about as much as the approved ALS drug edaravone.
