The elevated plus maze test showed a significant reduction in anxiety-related behaviors at 500 mg/kg of <em>P. marsupium</em>, with time spent in the open arms significantly increased (<em>p</em> &lt; 0.01) compared to stressed controls. This study highlighted its therapeutic potential, supported by DPPH assay-proven antioxidant activity, on stress-induced neurobehavioral changes in albino Wistar rats. Notably, the <em>P. marsupium</em> showed significant modulatory effects on stress hormones and oxidative stress. Cortisol levels were significantly suppressed in <em>P. marsupium</em> treated groups compared to the stress-induced group (<em>p</em> &lt; 0.01) and decreased the amount of thiobarbituric acid reactive substances (TBARS) in the brain. These findings reveal the neuroprotective potential of <em>P. marsupium</em> against stress, suggesting its promise for future treatments for anxiety and depression, pending further research. This study contributes to the expanding knowledge of natural compounds for ameliorating complex neurobehavioral changes and highlights the necessity of multi-faceted approaches to address their intricate manifestation.</div></div>","PeriodicalId":72447,"journal":{"name":"Brain disorders (Amsterdam, Netherlands)","volume":"17 ","pages":"Article 100194"},"PeriodicalIF":0.0,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143421251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Protein kinases are an increasingly popular class of pharmacological targets for disorders affecting peripheral tissues; nevertheless, developing kinase-targeted therapies for diseases affecting the central nervous system (CNS) is still difficult, mostly because of problems related to CNS drug discovery. A class of membrane-bound receptors known as receptor tyrosine kinases (RTKs) consists of an intracellular catalytic domain, a transmembrane domain, and an extracellular ligand-binding domain. RTKs are essential for many diverse biological functions, such as motility, growth, differentiation, and metabolism. The deregulation of RTK activity aids the development of several neurodegenerative diseases. The research found that in neurological diseases, changes were made to the vascular endothelial growth factor-B TAM receptors, tropomyosin receptor kinase, and epidermal growth factor receptor 1. Furthermore, it is shown that two important routes for neurite expansion and neuronal survival triggered by RTKs are the Wnt/catenin and PI3K/Akt/GSK-3β signaling pathways. PTKs, such as non-receptor tyrosine kinases, are also important for neuronal function and the development of neurodegeneration. When aberrantly produced or activated, non-receptor tyrosine kinase (Abelson kinase) c-Abl seems to have a role in both the normal development of brain tissue and the emergence of neurodegenerative diseases. The function of both RTKs and PTKs in neurodegenerative illnesses is described in this study, with special attention to their signaling pathways and prospects for treatment.</div></div>","PeriodicalId":72447,"journal":{"name":"Brain disorders (Amsterdam, Netherlands)","volume":"17 ","pages":"Article 100193"},"PeriodicalIF":0.0,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143395715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated the long-term effects of AuNPs in the striatum of a 6-hydroxydopamine (6-OHDA)-induced parkinsonian rat model. AuNP-conjugated transgene constructs (AuNP-DNA) of human aromatic acid decarboxylase (<em>AADC</em>) mixed with GTP cyclohydrolase 1 (<em>GCH1</em>) (1:1) was stereotaxically delivered to the striatum of either saline or 6-ODHA-lesioned Sprague Dawley rats. Long-term effects of AuNP-mediated gene therapy were evaluated on behavior, pro-inflammatory cytokine IL-1β expression, morphology of striatal microglia, dopamine biosynthesis and transgene expression. The 6-OHDA-induced neurobehavioral deficits were mitigated in gene therapy groups. This finding was correlated with significantly improved dopamine biosynthesis, inhibition of long-term expression of IL-1β, and suppression of sustained microglial activation. Both human <em>AADC</em> and <em>GCH1</em> transgenes were differentially expressed in the groups that underwent gene therapy. This suggests a successful AuNP-mediated transgene expression in the striatum, allowing for effective uptake and transcription of <em>AADC</em> and <em>GCH1</em> for DA re-synthesis. Furthermore, an IL-1β- and microglial-mediated inflammatory response was attenuated, preventing or suppressing neuroinflammation that is implicated in PD pathology.

Although the GBS development in Campylobacter-associated cases is considered to reveal less severe symptoms and more favourable prognosis after IVIG or plasmapheresis application, only 62 percent of COVID-19-associated GBS patients demonstrated the improvement, and long-term comorbidity is more expressive. The study also emphasizes that early symptoms and its severity are the key components for establishing the prognosis of the disease; patients with higher initial symptom severity initially often experience longer stays in the hospital and statistically worse outcomes. Moreover, different immunity to pathogens, revealed by MAbs, are underlain by dissimilar prognosis depending on the cause of infection. Thus, these results emphasise the need for a highly tailored approach to clinical management of GBS patients that would involve attention to the infectious pathogen. More study is required to fine-tune medical approach and enhance people's well-being since pathogens change over the time.

Apigenin, a flavonoid found in various herbs and plants, has garnered significant attention for its neuroprotective properties. This review aims to provide an update on the potential mechanisms by which apigenin exerts its protective effects in neurodegeneration. Apigenin has been shown to possess potent antioxidant activity, which is thought to play a crucial role in its neuroprotective effects. Oxidative stress, resulting from an imbalance between the production of reactive oxygen species (ROS) and the body's antioxidant defenses, is a hallmark of neurodegenerative diseases. Apigenin has been demonstrated to scavenge ROS, thereby reducing oxidative stress and mitigating the damage to neurons. Inflammation is another key feature of neurodegenerative diseases, and apigenin has been found to possess anti-inflammatory properties. Apigenin has been shown to inhibit the production of pro-inflammatory cytokines, such as TNF-α and IL-1β, which are elevated in neurodegenerative diseases. Moreover, apigenin has been demonstrated to suppress the activation of microglia, the resident immune cells in the brain, which are thought to contribute to neuroinflammation. In addition, apigenin has been shown to activate the PI3K/Akt signaling pathway, which is involved in promoting neuronal survival and preventing apoptosis. In this review, we focus on the underlying mechanisms and signaling pathways involved in neurodegenerative disorders, as well as the diverse beneficial effects of apigenin within these pathways. The literature surveyed spans from 1980 to 2024. Also, systematic search was performed in Embase, MEDLINE, Scopus, Web of Science Core Collection, and Google Scholar for relevant references.
