Summary

Story summary

Knocking out the TREM1 gene in mice improves memory, suggesting TREM1 as an Alzheimer’s target.
Blood TREM1 levels correlate with Alzheimer's risk, implying peripheral inflammation influences decline.
Amyloid-beta (A-beta) traps pathogens but becomes toxic in excess, forming plaques.
Neurofibrillary tangles, mainly tau, are more closely linked to cognitive impairment.
DR4 may protect against Alzheimer’s by preventing tau aggregation.
