3.4.3 Mechanistic insights from preclinical modelsbarrier, immune, and neurotransmitter changes Rodent models of PTSD provide causal evidence that psychological trauma disrupts the MGBA, leading to microbiota alterations, compromised gut barrier integrity, immune activation and neurotransmitter imbalance
99 Moreover, aging induces the expression of immune checkpoint-related molecules such as lymphocyte-activation gene 3 (LAG-3), programmed death protein 1 (PD-1), and cytotoxic T-lymphocyte-associated protein 4 (CTLA-4)
They activate some overlapping populations of neurons, but separate neurons, which, I think, is the basis for their additive effect
Studies also indicate that glycine induces a deeper sleep with increased time spent in REM sleep, promising a more restful experience
