Summary: This study identified two pathways, TLR4-dependent and independent, that promote platelet-dependent thrombus growth. It suggests that inhibiting TLR4 or p47phox could be a strategy to counteract thrombosis in SARS-CoV-2.

Summary: Cutaneous T-cell lymphomas (CTCL) are a group of diseases characterized by malignant clonal CD4+ T lymphocytes in the skin. Mycosis fungoides (MF) is the most common form of CTCL, and its pathogenesis is not fully understood. This study analyzed the expression of TLR pathway genes and miRNAs in MF samples, and found potential therapeutic possibilities and the influence of the TLR signaling pathway in the molecular pathogenesis of MF.

Summary: Antimicrobial peptides are important molecules in the organism's defense system. They can modulate the immune system and recognize molecules present in pathogens. Overstimulation of TLR4 can lead to uncontrolled inflammatory responses, which can be counteracted by antimicrobial peptides.

Summary: Schistosomiasis, a major parasitic disease, primarily affects economically underdeveloped tropical regions. Controlling the life cycle of intermediate host snails is crucial for preventing and controlling the disease. Exploring the immune interactions between the snails and schistosomes can provide valuable insights for further research and the development of comprehensive strategies.

Summary: In this study, it was observed that oleandrin has an effect on genes and miRNAs associated with TLR pathway in melanoma cells. The pathways of TLRs and hsa-miR-146a-5p and hsa-miR-21-5p may participate in the molecular mechanism of action of oleandrin.

Summary: This review examines the role of balancing selection in Toll-like receptors (TLRs), innate immune genes involved in pathogen recognition and immune response activation. The analysis of infection and fitness-based evidence, as well as population allelic frequencies and heterozygosity levels, reveals that balancing selection maintains variation in TLRs under specific conditions and in certain evolutionary lineages. However, the understanding of balancing selection in non-MHC immune genes remains incomplete.

Summary: This study reveals that activated microglia-derived neuroinflammation induces neuronal TLR2/4-p38/JNK activation, disrupting autophagy and leading to accumulation of alpha-synuclein aggregates and neurite shortening. Targeting neuronal TLR2/4 pathway might provide a mechanistic-based therapy for neurodegenerative diseases such as Parkinson's disease.

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 analyzed TLR genes from the genomes and transcriptomes of 102 amphibian species to understand their evolutionary patterns. Results showed that TLR genes can be divided into seven subfamilies, with TLR4 subfamily found only in Anura. Purification selection played a leading role in amphibian TLR evolution, and different domains had different evolution rates. Positive selection patterns and single-nucleotide polymorphisms were observed in TLR genes.

Summary: This study investigates the immunological action of complex pectin by studying its interaction with Toll-like receptors (TLRs). The research shows that pectic heteropolysaccharides (HPSs) derived from terrestrial plant cell walls can bind to TLR4 and activate the immune response. The findings provide a better understanding of the interaction between complex carbohydrates and proteins.

Summary: This review discusses the functions of Toll-like receptors (TLRs) in the tumor microenvironment and the pathways that activate immune responses. It also summarizes recent developments in nanotechnology for immunomodulation with TLR agonists. Nanotechnology can improve the efficacy of TLR agonist-based immunotherapy and address its limitations.

Summary: This study examines the interactions between danger-associated molecular patterns and human adenoviruses and their impact on vaccines. The interaction between human adenoviruses and HNP-1 can modify the response of antigen-presenting cells, influencing vaccine efficacy. HNP-1 binds to the capsids of human adenoviruses and directs them to Toll-like receptor 4 (TLR4), leading to internalization, inflammasome response, and IL-1β release.
