Oxidative stress and energy imbalance strongly correlate in neurodegenerative diseases. Repeated concussion is becoming a serious public health issue with uncontrollable adverse effects the human population, which involve cognitive dysfunction even permanent disability. Here, we demonstrate that traumatic brain injury (TBI) evokes oxidative stress, disrupts homeostasis, boosts neuroinflammation, further contributes to neuronal degeneration mouse brain. We also melatonin (an anti-oxidant...

Exposure to ethanol during early development triggers severe neuronal death by activating multiple stress pathways and causes neurological disorders, such as fetal alcohol effects or syndrome. This study investigated the effect of on intracellular events that predispose developing neurons for apoptosis via calcium-mediated signaling. Although underlying molecular mechanisms neurotoxicity are not completely determined, mitochondrial dysfunction, altered calcium homeostasis apoptosis-related...

Physical or psychological stress can cause an immunologic imbalance that disturbs the central nervous system followed by neuroinflammation. The association between inflammation and depression has been widely studied in recent years, though molecular mechanism is still largely unknown. Thus, targeting signaling pathways link to neuroinflammation might be a useful strategy against depression. current study investigated protective effect of melatonin lipopolysaccharide (LPS)-induced Our results...

SARS-CoV-2 papain-like protease (PLpro) covers multiple functions. Beside the cysteine-protease activity, facilitating cleavage of viral polypeptide chain, PLpro has additional and vital function removing ubiquitin ISG15 (Interferon-stimulated gene 15) from host-cell proteins to support coronaviruses in evading host's innate immune responses. We identified three phenolic compounds bound PLpro, preventing essential molecular interactions by screening a natural compound library. The X-ray...
