The 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model remains the most extensively utilized animal model for Parkinson's disease (PD). Treatment regimens are classified into three categories: acute, subacute, and chronic. Among these, the MPTP with probenecid (MPTP/p)-induced chronic mouse model is favored for its capacity to sustain long-term striatal dopamine depletion, though the resultant behavioral, biochemical, and molecular alterations require further validation.

Aniline Blue is a synthetic dye extensively used in various industries, including textiles, plastics, and biological research due to its effective staining properties. However, its environmental and health impacts, particularly its neurotoxic effects, are poorly understood. While the dye has been associated with carcinogenicity and organ toxicity, the neurobehavioral consequences of Aniline Blue exposure remain underexplored.

Comorbidities between gastrointestinal diseases and psychiatric disorders have been widely reported, with the gut-brain axis implicated as a potential biological basis. Thus, dysbiosis may play an important role in the etiology of schizophrenia, which is barely detected. Triple-hit Wisket model rats exhibit various schizophrenia-like behavioral phenotypes.

Glia contribute to the neuropathology of Parkinson disease (PD), but how they react opposingly to be beneficial or detrimental under pathological conditions, like promoting or eliminating SNCA/α-syn (synuclein alpha) inclusions, remains elusive. Here we present evidence that aux (auxilin), the homolog of the PD risk factor GAK (cyclin G associated kinase), regulates the lysosomal degradation of SNCA/α-syn in glia. Lack of glial GAK/aux increases the lysosome number and size, regulates lysosomal acidification and hydrolase activity, and ultimately blocks the degradation of substrates including SNCA/α-syn.

This study was undertaken to assess the antioxidant and neuropharmacological potentials of the methanol leaf extract of Acanthus ebracteatus (MAEL) through experimental and in silico methods. The phytochemical screening (PS) and GC-MS (gas chromatography-mass spectrometry) identified 28 phytochemicals with different classes in nature in MAEL. The MAEL revealed better antioxidant activity through various in vitro antioxidant assays.
