To analyze the gut bacterial microbiome in rats with painful diabetic neuropathy (PDN) compared to normal rats. Type 2 diabetes was induced via a high-fat and high-sugar diet combined low dose of streptozotocin. Glucose metabolism insulin sensitivity were evaluated using intraperitoneal glucose tolerance tests tests. The progression peripheral assessed mechanical withdrawal threshold thermal latency. Histopathological analysis rat colon tissues performed hematoxylin-eosin staining observe morphological changes. expression levels pro-inflammatory cytokines TNF-α IL-1β spinal cord measured enzyme-linked immunosorbent assay (ELISA). Fecal samples then collected for metagenomic sequencing analysis. Behavioral revealed reduced latency PDN Histological showed significant colonic mucosal damage inflammatory cell infiltration, suggesting impaired intestinal barrier function. Elevated further highlight inflammation's role PDN. Sequencing differences microbiota composition between control rats, altered Bacillota/Bacteroidota ratios increased Lactobacillus abundance. Functional annotation analysis, based on KEGG, EggNOG, CAZy databases, indicated enrichment metabolic pathways related carbohydrate amino acid metabolism, energy structure biogenesis Cluster identified higher functional clustering Metabolism Genetic Information Processing This study demonstrates that leads composition, disrupted pathways, inflammation, contributing pathological neuropathy. provides new insights into interplay neuropathy, offering potential avenues therapeutic interventions targeting metabolism.

Neuroinflammation, characterized by a complex interplay among innate and adaptive immune responses within the central nervous system (CNS), is crucial in responding to infections, injuries, disease pathologies. However, dysregulation of neuroinflammatory response could significantly affect neurons terms function structure, leading profound health implications. Although tremendous progress has been made understanding relationship between processes alterations neuronal integrity, specific implications concerning both structure have not extensively covered, with exception perspectives on glial activation neurodegeneration. Thus, this review aims provide comprehensive overview multifaceted interactions key inflammatory players, exploring mechanisms through which inflammation influences functionality structural integrity CNS. Further, it will discuss how these lead impairment functions architecture highlight consequences caused dysregulated functions, such as cognitive dysfunction mood disorders. By integrating insights from recent research findings, enhance our landscape set stage for future interventions that transform current approaches preserve CNS-related conditions.

Studies on host microbiota and their interactions with the central nervous system (CNS) have grown considerably in last decade. Indeed, it has been widely demonstrated that dysregulations of bidirectional gut–brain crosstalk are involved development several pathological conditions, including chronic pain. In addition, activation peripheral glial cells is also implicated pathogenesis progression pain other neurodegenerative disorders. Recent preclinical findings suggest gut plays a pivotal role regulating maturation, morphology function, possibly through action different microbial metabolites, most studied short-chain fatty acids (SCFAs).

Recently, mPFC was reported to participate in cancer-induced bone pain (CIBP) via mechanism central inflammation. STING a key component neuroinflammation neuron system by activating downstream TBK1 NF-κB signaling pathways. We aimed investigate whether regulated rat models CIBP.
