Second priority with excellent tractability (GPCR). F1can designated orphan drug in Japan provides development precedent. Cross-species evidence for neuroprotection is moderate. Skeptic correctly points out biphasic effects and need for conditional knockout to distinguish cause from consequence. Expert confirms no active Phase 2/3 programs in neurodegeneration, creating opportunity. MRT6160 (Mediar Therapeutics) small molecule agonist is the lead to watch.
## Mechanistic Overview
TREM2-Dependent Astrocyte-Microglia Cross-talk 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 (Triggering Receptor Expressed on Myeloid cells 2) signaling cascade represents a critical node in neuroinflammation regulation, with its dysfunction fundamentally altering astrocyte-microgli
