Summary: TLRs are essential for immune responses and can mediate inflammation by recognizing molecular patterns in pathogens and damaged cells. TLR ligands have gained attention in cancer research, especially in combination with cancer treatments like immunotherapy, chemotherapy, and radiotherapy (RT). However, the role of TLRs in cancer, particularly in response to radiation, is still poorly understood. This review examines how TLR signaling affects tumor response to RT and proposes a framework for TLR-based therapies with RT.

Summary: The innate immune system in vertebrates and invertebrates relies on conserved receptors and ligands, and pathways to initiate a rapid response against microbial infections and other sources of stress and danger. Research on NOD-like receptors (NLRs) has advanced in the past two decades, providing insight into the ligands and conditions that activate NLRs, as well as the outcomes of NLR activation in cells and animals. NLRs play crucial roles in diverse functions, such as transcription of MHC molecules and initiation of inflammation, and their activation can be direct or indirect depending on the ligands involved. Future discoveries will contribute to a better understanding of the molecular details and physiological consequences of NLR activation.

Summary: This review discusses the potential role of Toll-like receptors (TLRs) in the immunopathogenesis of CD. Although evidence from basic research is limited, differences in TLR expression and activation have been observed between active CD patients and controls or treated CD patients in some clinical studies. Therefore, TLRs may be part of the non-HLA-related genetic factors implicated in CD pathogenesis, considering their potential role in the interaction between the host immune system and environmental factors.

Summary: Inhibition of eukaryotic initiation factor 4A (eIF4A) is proposed as a strategy to combat pathogens. Rocaglates are highly specific eIF4A inhibitors, and in silico analysis identified 35 eIF4A variants that are potentially sensitive to rocaglates. In vitro assays confirmed the predicted resistance in Caenorhabditis elegans and Leishmania amazonensis, and the predicted sensitivity in Aedes sp., Schistosoma mansoni, Trypanosoma brucei, Plasmodium falciparum, and Toxoplasma gondii. These findings suggest that rocaglates could be effective against various insect, plant, animal, and human pathogens.

Summary: Innate immune receptors form complexes with secondary receptors to activate multiple signaling pathways, regulating homeostasis and immunity. A bovine homologue of Mincle (boMincle) has been characterized to be structurally and functionally similar to the human orthologue (huMincle), although there are some differences. BoMincle is predominantly expressed by myeloid cells, but mRNA transcripts were also detected in granulocytes, B cells, and T cells. BoMincle has the potential to recognize endogenous ligands, suggesting its role in homeostasis in cattle.

Summary: Neutrophil extracellular traps (NETs) are important innate defense mechanisms formed by polymorphonuclear neutrophils (PMNs) and composed of chromatin and microbicidal proteins. However, the exact mechanisms of Toxoplasma gondii-induced NET formation in cattle are still largely unknown, including signaling pathways and dynamics. In this study, we investigated the involvement of cell cycle proteins in T. gondii-induced NETs in bovine PMNs. Our findings showed that Ki-67 and lamin B1 signals were upregulated and relocated during T. gondii-induced NETosis, and nuclear membrane disruption was also observed. However, centrosome duplication, previously described in human PMN-derived NET formation, was not observed.

Summary: Various studies have demonstrated the importance of transmission and passage of alien and native pathogens in the establishment and spread of invasive species. This study focused on Egyptian geese, which are neozotic birds found in various continents. The presence of these geese in urban habitats in Central Europe, where they come into close contact with humans and their pets, raises concerns about the anthropozoonotic risks and endoparasites they may carry. The survey conducted in Germany revealed the presence of 13 metazoan endoparasite species in Egyptian geese, including the anthropozoonotic Echinostoma revolutum. The study also found differences in parasite load between rural and urban populations of Egyptian geese.

Summary: Chickens have a unique immune structure characterized by the absence of draining lymph nodes and the presence of well-developed mucosa-associated lymphoid tissue. The structure and development of chicken lymphoid tissues in the intestine, particularly Peyer's patches, have been poorly studied. However, the use of CSF1R-eGFP reporter transgenic chickens has allowed for the visualization and investigation of the development and distribution of these tissues. This research provides insights that could benefit mucosal vaccination strategies and the development of targeted vaccine delivery systems.
