## **Molecular Mechanism and Rationale**
The molecular mechanism underlying GDNF gradient establishment by Schwann cells involves a complex cascade of neurotrophic signaling pathways that become activated following motor neuron denervation and TDP-43 pathological clearance. GDNF (Glial cell line-Derived Neurotrophic Factor) functions as a potent chemoattractant and survival factor through its interaction with the GFRα1 (GDNF family receptor alpha-1) co-receptor and the transmembrane receptor ty
**Molecular Mechanism and Rationale**
The molecular foundation of STMN2 restoration as a prerequisite for axonal regeneration following TDP-43 clearance centers on the intricate relationship between nuclear TDP-43 function and microtubule dynamics regulation. TDP-43 (TAR DNA-binding protein 43) normally functions as a nuclear RNA-binding protein that directly binds to specific UG-rich sequences within the STMN2 pre-mRNA, particularly at exon 2a junction sites. This binding prevents aberrant spl
