**Background and Rationale**
Synaptic dysfunction represents one of the earliest pathological hallmarks in neurodegenerative diseases, often preceding neuronal death by years or decades. The integrity of synaptic connections relies heavily on trans-synaptic adhesion molecules, which serve as molecular bridges that maintain structural stability and facilitate proper synaptic transmission. Among these, the neurexin-neuroligin (NRXN-NLGN) system represents the most extensively characterized trans-
**Molecular Mechanism and Rationale**
The neurexin-neuroligin trans-synaptic adhesion system represents a critical molecular bridge that maintains synaptic integrity while potentially facilitating pathological tau propagation in neurodegenerative diseases. Neuroligin-1 (NLGN1), the primary target of this therapeutic approach, is a postsynaptic cell adhesion molecule that forms heterotypic interactions with presynaptic neurexins (NRXN1, NRXN2, NRXN3). This interaction occurs through the extracel
