TLR4 (Toll Like Receptor 4)

Collectively, we show OLs as an unrecognized source of HMGB1 during oxycodone exposure and establish a novel OL-microglia signaling axis underlying neuroinflammation. These insights emphasize the importance of glial crosstalk in opioid-related pathologies and may inform therapeutic strategies targeting HMGB1 signaling.

This study provides and defines the first systematic snRNA-seq profiles under OXJF-treated HACE mice. The potential mechanisms of OXJF in treating HACE were related to maintaining energy metabolism, inflammation and BBB homeostasis.

However, TRG therapy restored renal impairments via regulating antioxidative, anti-apoptotic, anti-inflammatory, and histo-architecture. Our findings were strongly supported by in-silico findings that demonstrated the potential binding of TRG with key regulatory genes.

GA co-treatment significantly ameliorated these alterations, reducing inflammatory and apoptotic markers, restoring SIRT-1, and suppressing p53 activation. Collectively, GA exerts hepatoprotective effects through modulation of the TLR-4/NF-κB/IL-6 pathway and restoration of the SIRT-1/p53 regulatory axis, highlighting its immunopharmacological potential in sepsis-induced hepatic dysfunction.

These results underscore the importance of considering the tissue-resident microbiome as a biomarker of risk to improve primary prevention of breast cancer. Significance: Obesity differentially modulates non-cancerous breast tissue microbial-associated molecular pattern signaling, enriching LPS and flagellin, to promote oxidative stress and DNA damage.

Overall, the implementation of the "two birds with one stone" strategy activates the systemic immune response and effectively inhibits tumor growth. This strategy provides a viable regimen for the management of appropriate doses to afford PTX as potent TLR4a.

PCE downregulated the expression of caspase-3 and nuclear factor kappa B (NF-κB) and B-cell lymphoma 2 (Bcl-2) associated X-protein (Bax) and toll like receptor 4 (TLR-4) but it increased the expression of Bcl-2 and nuclear factor erythroid 2-related factor 2 (Nrf-2) and heme oxygenase-1 (HO-1). The research showed that PCE treatment resulted in decreased blood sugar levels and better liver enzyme and lipid profile results and decreased lipid peroxidation and enhanced antioxidant enzyme activities and reduced oxidative stress in DM rats according to biochemical and histopathological results.

Emerging clinical and translational data indicate that disrupting this axis can sensitize MSS-CRC to ICIs: for example, Zanzalintinib combined with Atezolizumab reported survival benefit in the STELLAR-303 trial, and dual blockade of novel checkpoints with PD-(L)1 has been associated with enhanced immune activation in solid tumors. Targeting the MDSC-Treg axis therefore represents a promising strategy to overcome immunotherapy resistance in MSS/pMMR CRC.

Our findings indicated that S100A14 is a clinically relevant biomarker for early detection and a potential therapeutic target for BrM.

MCP-1 enhances AKT phosphorylation and cell proliferation, suggesting a link between immune signalling and follicle activation. These findings indicate that LPS-induced activation of TLR4 may interact with PI3K-AKT signalling to regulate primordial follicle activation and ovarian reserve maintenance.

We hypothesize that the pathogenesis of TD may involve elevated TLR4, which triggers overactivation of microglia in the brain resulting in the release of excessive IL-6, IL-8, and TNF-α. This process damages neurons and leads to tic symptoms in patients.

m214-sEV treatment reprograms secondary tumor-derived sEVs toward a less prometastatic cargo profile and decreases carboplatin resistance and cell migration. Enforced YKT6 overexpression abrogates these effects, establishing YKT6 as a key downstream effector. Collectively, these findings support engineered sEVs as a translatable strategy to overcome chemoresistance and disrupt pro-tumorigenic EV signaling in recurrent OC.
