- We investigated whether a water extract of ( Thunberg; WELB) could modulate inhibitory synaptic organization in a mouse model of pentylenetetrazol (PTZ)-induced kindling. Starting 14 days prior to the initial PTZ challenge, WELB (500 mg/kg) was delivered via oral gavage once daily. This treatment regimen was maintained for a total of 40 days, spanning the entire period until the animals reached the fully kindled state. Behavioral assessments revealed that WELB treatment significantly reduced seizure severity and Racine scores, prolonged the latency to clonic seizures, and shortened seizure duration, demonstrating potent anticonvulsant activity. Two-photon calcium imaging further showed that WELB markedly suppressed PTZ-induced neuronal hyperexcitability in the posterior parietal cortex, accompanied by decreased expression of neuronal activation markers, including c-fos, phosphorylated-calcium/calmodulin-dependent protein kinase IIα (p-CaMKIIα), and N-methyl-D-aspartate receptor 1 (NR1). In the hippocampus, WELB modulated the expression of GABAergic interneuron markers [glutamate decarboxylase 67 (GAD67), vesicular GABA transporter (VGAT), parvalbumin (PV), somatostatin (SOM)] and upregulated GABAergic gene transcripts [GABA-A receptor α1 subunit (Gabra1), GABA-A receptor α2 subunit (Gabra2), GABA transporter 1 (Gat1), GABA transporter 3 (Gat3), PV, SOM, cholecystokinin (CCK)] that were downregulated by PTZ kindling. Moreover, WELB enhanced the expression of GABAergic synaptic organization-related proteins (gephyrin, collybistin, neurexin-1β, neuroligin-2, and neuropilin-2), indicating its regulatory effect on inhibitory synaptic integrity. Collectively, these findings suggest that WELB may exert its anticonvulsant effects by functionally remodeling GABAergic synaptic organization-related factors, thereby restoring inhibitory circuit integrity and providing a mechanism-based therapeutic strategy for epilepsy and seizure-related neurological disorders. - Source: PubMed

Park Hee Ra - Neuroinflammation plays an important role in the pathophysiology of depression. Interleukin-17A (IL-17A), an inflammatory cytokine, is strongly associated with depression; however, the potential mechanisms through which IL-17A in the brain regulates depressive symptoms remain unknown. Our study aimed at finding out the potential pathway through which IL-17A in the brain regulates depressive-like behaviours. Anti-despair-like behaviours, an important index for evaluating depression in mice, are present in IL-17A knockout mice. Given that the hippocampus is a brain region that is implicated in depression, the level of IL-17A in the hippocampus was evaluated in chronic unpredictable mild stress (CUMS) mice, and the results revealed increased hippocampal IL-17A levels. The expression of IL-17A was subsequently regulated by the stereotactic injection of multivesicular liposomes loaded with IL-17A recombinant protein as a sustained release system, and the AAV-il17a or AAV-shRNA(il17a) into the hippocampus. IL-17A overexpression induced despair-like behaviour, and the anti-despair-like phenotype in IL-17A knockout mice was blocked by the restoration of IL-17A expression in the hippocampus, which demonstrated the role of IL-17A in depression. Gene microarray, UPLC‒MS/MS, Western blot and patch clamp analyses were used to determine the pathway through which IL-17A regulates despair-like behaviours. Enhanced inhibitory synaptic transmission was detected in IL-17A-knockout mice. Furthermore, reducing the expression of the GABAA receptor α2 subunit (GABRA2) abrogated antidespair-like behaviour in IL-17A knockout mice, and hippocampal GABARA2 overexpression alleviated despair-like behaviour in CUMS mice. These results proved that GABRA2-mediated inhibitory synaptic transmission participated in the regulation of depressive-like behaviours by IL-17A. Our results revealed a vital role for IL-17A in depression and suggested that GABRA2 is the key molecule involved in the regulation of depression by IL-17A, indicating its potential as a therapeutic target for depression. - Source: PubMed

Li YingYang ShengyaLi HaoranLi HuachaoSun YunchuanHe XinyingZhang YingruWang Yan - Paternal environmental factors before conception and during sperm development may influence the offspring's health later in life. This study aimed to investigate whether paternal exposure to anabolic-androgenic steroids (AAS) before conception predisposes mouse offspring to autism spectrum disorder (ASD)-like behavior. For this purpose, male Swiss mice were randomly divided into two groups: the control group received peanut oil, while the treated group was administered testosterone propionate (7.5 mg/kg, s.c.) twice a week for five weeks. After this period, these males were mated, and their offspring underwent a behavioral test battery at 70 days of age, including the open field test, object recognition task, three-chamber social approach test, and light-dark box test. At the end of the experiment, the hippocampus was dissected for RNA analysis. Our results indicate that paternal AAS treatment induces long-lasting behavioral alterations in both female and male offspring, including increased anxiety-like behavior, impaired memory, and deficits in social interaction. Additionally, a strong effect of paternal AAS treatment during preconception period was verified in Gad1, Gabra2 and Bdnf expression. These findings suggest that paternal AAS exposure may program neurodevelopmental vulnerabilities in offspring, contributing to ASD-like phenotypes. - Source: PubMed

Despite the various pharmacological treatments available, patients with chronic pain often remain with significant disabilities and unsatisfactory pain control. Cannabis and cannabinoids are sometimes used in the treatment of chronic pain as they have been shown to be useful in a subset of patients. Some of the adverse effects associated with cannabis use, such as cannabis use disorder (CUD) and cannabis-induced psychosis, have been associated with several genetic variants. Despite this, the paucity of the data or the contradictory results for reported variants limits our ability to use them as genetic markers to personalize cannabis treatment tailored to patients’ genetic background. The aim of this genetic association study was to investigate the link between previously reported genes and cannabinoid response in terms of pain response, CUD and risk of psychotic adverse events in patients with chronic pain. - Source: PubMed
