## Soluble TREM2 (sTREM2) as Therapeutic Mimic — Decoupling Phagocytosis from Inflammation ### The Central Paradox of TREM2 Biology TREM2 signaling presents a fundamental therapeutic paradox: the receptor's beneficial phagocytic functions and its potentially harmful inflammatory amplification effects are mediated through the same DAP12-ITAM-SYK signaling axis. Classical receptor pharmacology suggests that a single downstream cascade cannot easily be selectively activated to produce one set of

## Molecular Mechanism and Rationale APOE4-Specific Lipidation Enhancement Therapy targets the fundamental molecular deficiency that distinguishes the APOE4 isoform from its neuroprotective counterparts, APOE2 and APOE3. The apolipoprotein E (APOE) protein exists in three major human isoforms, differing by only two amino acids: APOE2 (Cys112, Cys158), APOE3 (Cys112, Arg158), and APOE4 (Arg112, Arg158). These seemingly minor variations have profound structural and functional consequences, partic
