Chitin-Induced Carbotype Conversion in Vibrio vulnificus [PDF]
Infection and Immunity, 2011 ABSTRACT As an etiological agent of bacterial sepsis and wound infections, Vibrio vulnificus is unique among the Vibrionaceae . The most intensely studied of its virulence factors is the capsular polysaccharide (CPS).

Two transmembrane transcriptional regulators coordinate to activate chitin-induced natural transformation in Vibrio cholerae. [PDF]
PLoS GenetABSTRACT Transcriptional regulators are a broad class of proteins that alter gene expression in response to environmental stimuli. Transmembrane transcriptional regulators (TTRs) are a subset of transcriptional regulators in bacteria that can directly regulate gene expression while remaining anchored in the membrane ...

Microfluidic Interrogation of Chitin-Induced Calcium Oscillations in the Moss Physcomitrium patens [PDF]
Plants (Basel)Plants defend against pathogens such as fungi by initiating coordinated structural and chemical responses. Pathogen perception triggers rapid cytosolic calcium influx and calcium oscillations that drive defense gene expression, yet the mechanisms by which these signals encode stressor intensity and propagate systematically remain unclear.

Conservation of Chitin-Induced MAPK Signaling Pathways in Rice and Arabidopsis [PDF]
Plant and Cell Physiology, 2017 Perception of microbe-associated molecular patterns (MAMPs) including chitin by pattern recognition receptors (PRRs) rapidly induces activation of mitogen-activated protein kinase (MAPK) cascades. However, how PRRs transmit immune signals to the MAPK cascade is largely unknown.

Chitin modulates innate immune responses of keratinocytes. [PDF]
PLoS ONE, 2011 BACKGROUND: Chitin, after cellulose the second most abundant polysaccharide in nature, is an essential component of exoskeletons of crabs, shrimps and insects and protects these organisms from harsh conditions in their environment.

Chitin Triggers Tissue-Specific Immunity in Wheat Associated With Fusarium Head Blight
Frontiers in Plant Science, 2022 Fusarium graminearum is one of the primary causal agents of Fusarium head blight (FHB) on wheat and barley. FHB reduces grain yield and contaminates grain with various mycotoxins, including deoxynivalenol (DON).

Chitin induces accumulation in tissue of innate immune cells associated with allergy [PDF]
Nature, 2007 Allergic and parasitic worm immunity is characterized by infiltration of tissues with interleukin (IL)-4- and IL-13-expressing cells, including T-helper-2 cells, eosinophils and basophils. Tissue macrophages assume a distinct phenotype, designated alternatively activated macrophages.

TLR-2 and IL-17A in Chitin-Induced Macrophage Activation and Acute Inflammation [PDF]
The Journal of Immunology, 2008 Abstract Chitin is a ubiquitous polysaccharide in fungi, insects, and parasites. To test the hypothesis that chitin is an important immune modulator, we characterized the ability of chitin fragments to regulate murine macrophage cytokine production in vitro and induce acute inflammation in vivo. In this study, we show that chitin is a
