Although neuroimaging studies have highlighted large-scale neural circuit dysfunctions, the underlying pathogenic mechanisms at the synaptic level remain poorly understood. The glutamatergic system, particularly the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR), is hypothesized to play a pivotal role in stress-induced pathologies, yet its specific role in PTSD + MDD comorbidity has not been elucidated.

The face, construct, and predictive validity of the model were verified through behavioural monitoring, molecular biological assessments, and drug treatment with paroxetine (PRX).<b>Results:</b> The combined SPS&S + CUMS paradigm resulted in core PTSD- and MDD-like behavioural deficits, including severe anhedonia and significant cognitive impairment.
