C-type lectin receptors (CLRs) are powerful pattern-recognition receptors that discern 'self' and 'non-self' in our body and protect us from invasive pathogens by mediating immune recognition and response. The gastrointestinal tract is very important for the maintenance of homeostasis; it is the largest shelter for the billions of microorganisms in the body and CLRs play a crucial regulatory role in this system. This study focuses on several CLRs, including Dectin-1, Dectin-2, Dectin-3 and Mincle. We summarize the roles of CLRs in maintaining gastrointestinal immune-system homeostasis, especially their functions in mediating immune recognition and responses in the gut, discuss their relationships to some diseases, highlight the significance of CLR-mediated sensing of microbial and non-microbial compounds in the gut immune system and identify new therapeutic targets.

Generalized pustular psoriasis (GPP) is a rare human autoinflammatory disorder with life-threatening systemic effects. Keratinocyte-derived interleukin (IL)-36 signaling has been identified as a key mediator of immune response in the skin of affected individuals. Recognition of various mutations along the IL-36 axis and the downstream nuclear transcription factor κB (NF-κB) signaling have established GPP as genetically, immunologically, and histopathologically distinct and amenable to immunomodulation, which is epitomized by the recent success of IL-36 antagonism.

Background: Identifying patients with latent tuberculosis infection (LTBI) is challenging. This is particularly true amongst immunocompromised hosts, in whom the diagnostic accuracy of available tests is limited. The authors evaluated the impact of routine pretransplant review by a transplant infectious diseases (TID) physician on LTBI screening in allogeneic hematopoietic stem cell transplant (alloHSCT) recipients.

The recent advancements in cancer immunotherapy have spotlighted the potential of natural killer (NK) cells, particularly chimeric antigen receptor (CAR)-transduced NK cells. These cells, pivotal in innate immunity, offer a rapid and potent response against cancer cells and pathogens without the need for prior sensitization or recognition of peptide antigens. Although NK cell genetic modification is evolving, the viral transduction method continues to be inefficient and fraught with risks, often resulting in cytotoxic outcomes and the possibility of insertional mutagenesis.

Infectious diseases drive wild plant evolution and impact crop yield. Plants, like animals, sense biotic threats through pattern recognition receptors (PRRs). Overly robust immune responses can harm plants; thus, understanding the tuning of defense response mechanisms is crucial for developing pathogen-resistant crops.

Background/aim: The Kaplan-Meier curves for patients treated with immune checkpoint inhibitors (ICIs) display a small group of potentially-cured patients with long-term survival, creating a 'kangaroo-tail' shape of the survival curve. However, the mechanistic basis of this phenomenon and what occurs in patients whose cancer is resistant to ICIs remain unclear. The present study aimed to answer these questions.
