Despite the availability of NSAIDs and glucocorticoids, pain management becomes increasingly challenging due to central and peripheral sensitization. Previous studies have shown that Matrix metalloproteinase 2 (MMP2) promotes neuroinflammation by cleaving extracellular matrix proteins and activating pro-inflammatory cytokines. Folic acid acts as a promising candidate for the treatment of neuroinflammatory diseases due to its neuroprotective effects. However, the role of folic acid in inflammatory pain remains unclear. This study investigated the analgesic mechanisms of folic acid in inflammatory pain. Adult rats underwent inflammatory pain by injecting complete freund's adjuvant (CFA) into the right hindpaw. Behavioral tests were used to assess the paw withdrawal threshold (PWT) and paw withdrawal latency (PWL). The results demonstrated that CFA injection induced abnormal mechanical and thermal pain and increased MMP2 expression in L3-L5 DRG and SDH of CFA rats. MMP2 was mainly expressed in neurons rather than glial cells in L3-L5 DRG of CFA rats. We further discovered that MMP2 inhibitor auraptene or knockdown alleviated inflammatory pain in CFA rats. Interestingly, we observed that long-term folic acid treatment reversed MMP2 overexpression, resulting in sustained relief of chronic inflammatory pain. Consistently, long-term folic acid treatment also relieved pain-induced anxiety. These results indicated that folic acid had a protective role in chronic inflammatory pain and pain-induced anxiety by repressing MMP2 expression. Folic acid or auraptene might be promising therapeutic options for the treatment of chronic inflammatory pain.</div></div>","PeriodicalId":19139,"journal":{"name":"Neuropharmacology","volume":"269 ","pages":"Article 110352"},"PeriodicalIF":4.6,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143402438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Related research shows activating metabotropic glutamate receptors holds therapeutic potential. Agonist-positive allosteric modulations (ago-PAMs) not only activate metabotropic glutamate receptors but also enhance glutamate-induced responses, offering a promising treatment strategy. However, the molecular mechanisms by which ago-PAM enhances glutamate-induced responses remain unclear, as does the potential influence of glutamate on ago-PAM. In this study, Gaussian accelerated molecular dynamics and tau random acceleration molecular dynamics simulations were employed to investigate the molecular mechanism between ago-PAM and glutamate in full-length mGlu<sub>2</sub>. Results suggest that the ago-PAM JNJ-46281222 enhances the binding affinity and residence time of glutamates in the Venus flytrap (VFT) domains by initiating a variant reverse communication from the heptahelical transmembrane (7TM) domains to VFTs via the cysteine-rich domains. Meanwhile, glutamate facilitates the interaction between Trp676 and Glu701 to further induce the relaxation of TM5, promoting the opening of the PAM-binding pocket. Glutamate can also promote the upward rotation of the cyclopropylmethyl group of the JNJ-46281222 to bring the TM6-TM6 distance closer. Nevertheless, it remains uncertain how the binding between mGlu<sub>2</sub> and G protein differs when induced by small molecules binding in allosteric sites, orthosteric sites, or both. In conclusion, this study shed new light on the positive coordination relationship between ago-PAM and glutamate in the full-length mGlu<sub>2</sub> receptor, which could help develop novel and more effective ago-PAM to treat schizophrenia.</div></div>","PeriodicalId":19139,"journal":{"name":"Neuropharmacology","volume":"269 ","pages":"Article 110351"},"PeriodicalIF":4.6,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143391444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most importantly correlation analysis between FC and feeding behavior revealed that different brain areas potentially drive reduced food intake in male and female rats. Our findings underscore the distributed and distinctly sex divergent neural network engaged by each of these anorexic peptides and suggest that different brain areas may be the primary drivers of the feeding outcome in male and female rats. Moreover, prominent activity and connectivity alterations observed in brain areas not typically associated with feeding behavior in both sexes may either indicate novel feeding centers or alternatively suggest the involvement of these substances in behaviors beyond feeding and metabolism.

The administration of Tica improved motor function (open field test, hanging wire test) and restored striatal histological features. Additionally, Tica opposed the rotenone effect and markedly obliterated the striatal α-synuclein content but enhanced the protein expression of tyrosine hydroxylase and dopamine content. On the molecular level, Tica inhibited striatal endoplasmic reticulum stress (ERS) as evidenced by the downregulation of the ER-resident transmembrane sensor inositol-requiring enzyme 1 alpha and its downstream molecular targets, TNF receptor-associated factor 2 and c-Jun N-terminal kinase, along with a reduction in caspase-3 activity.
