Published: June 2019

Kawasaki disease (KD) is a pediatric vasculitis syndrome that is often involves coronary artery lesions (e. g., coronary artery aneurysms). Although its causal factors and entire pathogenesis remain elusive, the available evidence indicates that the pathogenesis of KD is closely associated with dysregulation of immune responses to various viruses or microbes. In this short review, we address several essential aspects of the etiology of KD with respect to the immune response to infectious stimuli: 1) the role of viral infections, 2) the role of bacterial infections and the superantigen hypothesis, 3) involvement of innate immune response including pathogens/microbe-associated molecular patterns and complement pathways, and 4) the influence of genetic background on the response to infectious stimuli. Based on the clinical and experimental evidence, we discuss the possibility that a wide range of microbes and viruses could cause KD through common and distinct immune processes.

Sepsis is a common systemic infectious disease followed by extremely high incidence and mortality with no effective treatment and clinical drugs. As a key mediator involved in infection and immunity, it has been reported that sepsis patients are accompanied by increased heat shock protein 70 (HSP70). Trained immunity is a novel innate immunity approach that can be activated by β-glucan to fight against sepsis.

Purpose Of Review: The purpose of this review is to summarize the current understanding of cell-autonomous innate immune pathways that contribute to bone homeostasis and disease.

Recent Findings: Germ-line encoded pattern recognition receptors (PRRs) are the first line of defense against danger and infections. In the bone microenvironment, PRRs and downstream signaling pathways, that mount immune defense, interface intimately with the core cellular processes in bone cells to alter bone formation and resorption.

Article Synopsis
  • Heat stress (HS) prompts neuroinflammation and cognitive issues in the brain, leading to a study that compared the gene expression of mouse hippocampal tissue under HS conditions versus control.
  • Analysis showed that HS exposure resulted in 210 differentially expressed genes, indicating significant changes, with 72 genes upregulated and 138 downregulated.
  • Notably, the study found that taurine treatment could improve cognitive functions affected by HS, suggesting potential strategies for mitigating heat-induced cognitive impairments in vulnerable groups.

Infectious bone defects present a significant clinical challenge, characterized by infection, inflammation, and subsequent bone tissue destruction. Traditional treatments, including antibiotic therapy, surgical debridement, and bone grafting, often fail to address these defects effectively. However, recent advancements in biomaterials research have introduced innovative solutions for managing infectious bone defects.

Introduction: Leprosy, a chronic infectious disease, is closely linked to the host immune response. According to the WHO, leprosy patients (L) and household contacts (HHC) are classified into subgroups: paucibacillary (PB) and multibacillary (MB), witch reflect the degree of infection in patients and the level of exposure of their contacts. The main goal of this study was to: i) establish a comprehensive overview of soluble mediator signatures of PBMCs upon antigen-specific stimuli and ii) identify whether the chemokine (CH) and cytokine (CY) signatures were associated with distinct clinical manifestations in (L) and immune response profiles in (HHC).
