In this study, our purpose was to explore whether ASDZL affects the function of the SNARE complex by regulating the BDNF/TrkB signaling pathway or downregulating the expression levels of the main factors (P75, JNK1, and NF-κB) that inhibit the activation of related pathways and play a regulatory role in the initial process of vesicle circulation in the prefrontal cortex (PFC), corpus striatum, and hippocampus of ADHD model SHRs. This evidence concerns the gene NTRK2 and attention deficit-hyperactivity disorder.
