Identifying the Patterns of Pattern Recognition Receptors

Pathogen Associated Molecular Patterns, Pattern Recognition Receptors and Pediatric Sepsis

The mortality of septic shock in the pediatric population has improved over the last 2 decades with better supportive care however it still remains unacceptably high. Exaggerated inflammatory responses early in septic shock have been associated with poor outcomes. Regulation of the magnitude of the early inflammatory response is not well understood. The earliest aspect of the inflammatory respo...

Immunity is based on self/nonself discrimination. In vertebrates, two major systems, innate and adaptive immune systems, constitute host defense against invading microbes. Adaptive immunity is characterized by specific immune responses through B- or T-cell antigen receptors that are generated by somatic recombination, whereas nonspecific responses to microbes had been accentuated in innate immu...

Pattern Recognition Receptors and Inflammation

Infection of cells by microorganisms activates the inflammatory response. The initial sensing of infection is mediated by innate pattern recognition receptors (PRRs), which include Toll-like receptors, RIG-I-like receptors, NOD-like receptors, and C-type lectin receptors. The intracellular signaling cascades triggered by these PRRs lead to transcriptional expression of inflammatory mediators th...

Pattern Recognition Receptors and Autophagy

The immune system senses exogenous threats or endogenous stress through specialized machinery known as pattern recognition receptors (PRRs). These receptors recognize conserved molecular structures and initiate downstream signaling pathways to control immune responses. Although various immunologic pathways mediated by PRRs have been described, recent studies have demonstrated a link between PRR...
