Comparing 2 hypotheses side-by-side
## Mechanistic Overview Cell-Type Specific TREM2 Upregulation in DAM Microglia starts from the claim that modulating TREM2 within the disease context of Alzheimer's Disease can redirect a disease-relevant process. The original description reads: "TREM2 (Triggering Receptor Expressed on Myeloid Cells 2) shows marked upregulation in disease-associated microglia (DAM) within the SEA-AD Brain Cell Atlas. Analysis of middle temporal gyrus single-nucleus RNA-seq data reveals TREM2 expression is enrich
## Mechanistic Overview TREM2-Mediated Astrocyte-Microglia Crosstalk in Neurodegeneration starts from the claim that modulating TREM2 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "**Molecular Mechanism and Rationale** The TREM2-mediated astrocyte-microglia crosstalk hypothesis centers on the disruption of critical intercellular communication networks that maintain brain homeostasis. TREM2 (Triggering Receptor Expressed o
