The vagus nerve (VN) is the primary parasympathetic nerve, providing two-way communication between the body and brain through a network of afferent and efferent fibers. Evidence suggests that altered VN signaling is linked to changes in the neuroimmune system, including microglia. Dysfunction of microglia, the resident innate immune cells of the br...
From preclinical and clinical findings, it has been shown that the amygdala is a critical mediator of stress and primary target for stress effects in the brain. We investigated the neuroprotective effect of Ginkgolide B (GB) in repeated restraint stress-induced behavioral deficit and amygdalar inflammation in mice. Mice were orally pre-treated with...

The clinical efficacy of haloperidol in the treatment of psychosis has been limited by its tendency to cause parkinsonian-like motor disturbances such as bradykinesia, muscle rigidity and postural instability. Oxidative stress-evoked neuroinflammation has been implicated as the key neuropathological mechanism by which haloperidol induces loss of do...
Males primarily use testosterone as a sex hormone. Through its effects on the androgen receptor, it is released by the interstitial cells of the testes and is in charge of the male external genitalia development as well as the internal reproductive glands and ducts during adolescence and maturity. Additionally, testosterone is required for the desc...
Brain aging, which involves a progressive loss of neuronal functions, has been reported to be premature in probands affected by schizophrenia (SCZ).
