Summary: Yellow catfish is an important fish in China's rivers. Viral and bacterial diseases have caused serious problems in domestic fisheries and threaten aquaculture production. This study investigated the role of TLR3 in the immune response of hybrid yellow catfish to viral infection. The results showed that TLR3 played a significant role and provide a basis for further research and cultivation of disease-resistant yellow catfish.

Summary: Studies have shown that Toll-like Receptor 3 (TLR3) depends on the length of its ligands for triggering a robust immune response. In this study, the cryo-electron microscopy structure of TLR3 bound to a synthetic RNA ligand of average length 400 base pairs was determined. The structure revealed that TLR3 units form a highly organized and cooperative cluster along the double-stranded RNA helix, suggesting that ligand-induced clustering of TLR3 triggers the assembly of signaling adaptors and initiates a strong innate immune response.

Summary: In this study, 12 Toll-like receptor (TLR) genes were identified in black rockfish, and their characteristics were analyzed. The results showed that these genes belong to five subfamilies and are highly expressed in immune tissues. Additionally, the study found that the expression of these genes increased significantly after poly (I:C) injection.

Summary: Immunotherapy is being investigated as a breakthrough treatment option for glioblastoma, with poly(I:C)/poly-ICLC potentially playing a key role in activating lymphocytes and enhancing immunological responses. Studies show that poly(I:C) or poly-ICLC treatment for glioblastoma has the potential to activate lymphocytes and enhance immune responses.

Summary: In this study, the expression and tissue distribution of TLR2 and TLR4 in Schizothorax prenanti were investigated. It was found that both TLR2 and TLR4 were widely expressed in various tissues, especially immune-related tissues. Injection of poly (I:C) significantly upregulated the expression of these proteins, indicating their potential roles in antiviral immunity and pathological processes in S. prenanti.

Summary: The study identified 12 members of the TLR gene family in the Japanese meagre genome, distributed across 10 chromosomes. Evolutionary analysis placed the TLR genes into different subfamilies, with highly consistent conserved motifs. qRT-PCR assays revealed higher expression levels of TLRs in immune tissues of Japanese meagre.

Summary: Gastric cancer is associated with the exhaustion of TCD8(+) cells, but Toll-like receptor agonists such as poly (I:C) can restore the normal phenotype and function of these cells. In this study, treatment with poly (I:C) alleviated the expression of PD-1 and LAG3, improved cell proliferation, and increased cytokine release in TCD8(+) cells from both peripheral blood and tumor-infiltrating sites of gastric cancer patients.

Summary: SARS-CoV-2 cell entry in the nasal mucosa is promoted by the activation of innate immune signals via TLR3, but this expression is suppressed in the presence of the corticosteroid fluticasone propionate (FP). Further studies are needed to determine whether FP can suppress SARS-CoV-2 viral cell entry.

Summary: Famotidine has no effect on viral replication but can modulate specific signaling pathways, reducing TLR3-dependent signaling processes and subsequent activation of IRF3 and the NF-kappa B pathway, leading to control of antiviral and inflammatory responses.

Summary: In ovo vaccination with herpesvirus of turkey (HVT) enhances immune competence in chickens, and the recommended dose (RD) of 6080 plaque-forming-units (PFU) offers the most optimal effects. This study found that HVT-RD increases transcription levels of TLR3 and IFN c R2 in meat-type chickens, leading to enhanced cellular immune responses. However, the addition of TLR3 agonist poly(I:C) only provides minimal adjuvant/dose-sparing effects.

Summary: The study demonstrated that Poly (I: C) treatment could significantly inhibit REV replication in chicken macrophage-like cell line, HD11, switch HD11 into M1-like polarization, promote interferon-beta secretion, and activate TLR-3 signaling to block REV replication. This provides a theoretical reference for further research on the pathogenic mechanism of REV and Poly (I: C) as a potential therapeutic intervention against REV infection.

Summary: Argon preconditioning protects neuronal cells from cell death by reducing apoptosis, decreasing the expression of Toll-like receptors (TLRs), enhancing phosphorylation of ERK1/2, and suppressing NF-kappa B and Akt expression. It also inhibits the expression of caspase-3, Bcl-2, interleukin-8, and heat shock proteins. Argon preconditioning may be a promising therapeutic alternative for conditions like stroke.

Summary: The development and application of AI algorithms are of great significance for the removal of cSCC, as they can improve operational efficiency and accuracy, especially for moderately and poorly differentiated tumors/ neoplasms. Further improvement is needed to maintain sensitivity to surrounding tissue and determine anatomical positioning.

Summary: This study investigated the role and mechanisms of NTS in stress-induced hair growth inhibition. The results demonstrated that NTS effectively counteracted hair growth inhibition caused by stress and regulated the expression of multiple genes related to hair growth at the transcriptional level.
