Autism spectrum disorder (ASD) is a complex neurodevelopmental characterized by impairments in social interaction and communication along with repetitive stereotypic behaviors. Currently, there are no specific biomarkers for diagnostic screening or treatments available autistic patients. Numerous genetic disorders associated high prevalence of ASD, including tuberous sclerosis complex, phosphatase tensin homolog, fragile X syndrome. Preclinical investigations animal models these diseases have revealed irregularities the PI3K/Akt/mTOR signaling pathway as well ASD-related behavioral defects. Reversal downstream molecular irregularities, mTOR hyperactivation, improved deficits observed preclinical investigations. Plant bioactive molecules shown beneficial pre-clinical evidence ASD treatment modulating pathway. In this review, we summarize involvement alterations components its critical impact on development autism disorder. Mutations negative regulators mTORC1, such TSC1, TSC2, PTEN, result ASD-like phenotypes through disruption mTORC1-mediated signaling. We further discuss various naturally occurring phytoconstituents that been identified to be modulate prevent contribute therapeutic effects ASD.

As a small molecule flavonoid, astragalin (AST) has anti-inflammatory, anti-cancer, and anti-oxidation effects. However, the impact molecular mechanism of AST in Alzheimer's disease (AD) are still not clear. This study aims to investigate neuroprotective effect on APP/PS1 mice Aβ25-35-injured HT22 cells. In this study, we found that ameliorated cognitive dysfunction, reduced hippocampal neuronal damage loss, Aβ pathology mice. Subsequently, activated autophagy up-regulated levels autophagic flux-related protein Aβ25-35-induced injury Interestingly, down-regulated phosphorylation level PI3K/Akt-mTOR pathway-related proteins, which was reversed by inhibitors 3-Methyladenine (3-MA) or Bafilomycin A1 (Baf A1). At same time, consistent with impacts Akt inhibitor MK2206 mTOR rapamycin, inhibited cells were administration AST. Taken together, these results suggested played key roles AD via stimulating pathway-mediated flux. revealed new regulation behind neuroprotection for treatment.

Antioxidant peptides are currently a hotspot in food science, pharmaceuticals, and cosmetics. In different fields, the screening, activity evaluation, mechanisms, applications of antioxidant pivotal areas research. Among these topics, efficient screening stands at forefront cutting-edge To this end, with novel technologies has significantly accelerated research process, gradually replacing traditional approach. After screened identified, time-consuming evaluation is another indispensable procedure, especially vivo models. Cellular rodent models have been widely used for whilst non-rodent provide an solution, even potential high-throughput screening. Meanwhile, further molecular mechanisms can elucidate essence underlying activity, which related to several signaling pathways, including Keap1-Nrf2/ARE, mitochondria-dependent apoptosis, TGF-β/SMAD, AMPK/SIRT1/PGC-1α, PI3K/Akt/mTOR, NF-κB. Last but not least, broad manufacture, therapy, cosmetics industry, requires systematic review. This review introduces peptides, categorized new vision.

As major public health concerns associated with a rapidly growing aging population, neurodegenerative diseases (NDDs) and neurological are important causes of disability mortality. Neurological affect millions people worldwide. Recent studies have indicated that apoptosis, inflammation, oxidative stress the main players NDDs critical roles in processes. During aforementioned inflammatory/apoptotic/oxidative procedures, phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target rapamycin (mTOR) pathway plays crucial role. Considering functional structural aspects blood–brain barrier, drug delivery to central nervous system is relatively challenging. Exosomes nanoscale membrane-bound carriers can be secreted by cells carry several cargoes, including proteins, nucleic acids, lipids, metabolites. significantly take part intercellular communications due their specific features low immunogenicity, flexibility, great tissue/cell penetration capabilities. Due ability cross these nano-sized structures been introduced as proper vehicles for multiple studies. In present systematic review, we highlight potential therapeutic effects exosomes context targeting PI3K/Akt/mTOR signaling pathway.
