Chitin nanofiber elucidates the elicitor activity of polymeric chitin in plants

open access: yesFrontiers in Plant Science, 2015
Chitin, an N-acetyl-D-glucosamine polymer, is a component of fungal cell walls and a microbe/pathogen-associated molecular pattern that elicits plant defense responses.

Nanostructural organization of naturally occurring composites - part II: silica-chitin-based biocomposites [PDF]

open access: yes, 2012
Investigations of the micro- and nanostructures and chemical composition of the sponge skeletons as examples for natural structural biocomposites are of fundamental scientific relevance.

ATL9, a RING zinc finger protein with E3 ubiquitin ligase activity implicated in chitin- and NADPH oxidase-mediated defense responses. [PDF]

open access: yesPLoS ONE, 2010
Pathogen associated molecular patterns (PAMPs) are signals detected by plants that activate basal defenses. One of these PAMPs is chitin, a carbohydrate present in the cell walls of fungi and in insect exoskeletons.

Effect of the degree of acetylation on the physicochemical properties of α-chitin nanofibers [PDF]

open access: yes, 2020
Available online 27 March 2020.The effective utilization of abundant α-chitin resources for materials engineering applications requires methods for controlling the physicochemical properties of α-chitin nanofiber (NF) dispersions.

Arabidopsis CPK5 Phosphorylates the Chitin Receptor LYK5 to Regulate Plant Innate Immunity

open access: yesFrontiers in Plant Science, 2020
Chitin, a major component of the fungal cell wall, triggers plant innate immunity in Arabidopsis via a receptor complex including two major lysin motif receptor-like kinases, AtLYK5, and AtCERK1.

KNR4, a suppressor of Saccharomyces cerevisiae cwh mutants, is involved in the transcriptional control of chitin synthase genes [PDF]

open access: yes, 1999
The KNR4 gene, originally isolated by complementation of a K9 killer-toxinresistant mutant displaying reduced levels of both 1,3-b-glucan and 1,3-bglucan synthase activity, was recloned from a YCp50 genomic library as a suppressor of Saccharomyces ...

Physiological and morphological aspects of Aedes aegypti developing larvae: effects of the chitin synthesis inhibitor novaluron. [PDF]

open access: yesPLoS ONE, 2012
Population control of the dengue vector mosquito, Aedes aegypti, is difficult due to many reasons, one being the development of resistance to neurotoxic insecticides employed.

Chitin-induced T6SS in Vibrio cholerae is dependent on ChiS activation

open access: yesMicrobiology, 2018
Vibrio cholerae regularly colonizes the chitinous exoskeleton of crustacean shells in the aquatic region. The type 6 secretion system (T6SS) in V. cholerae is an interbacterial killing device. This system is thought to provide a competitive advantage to V. cholerae in a polymicrobial community of the aquatic region under nutrient-poor conditions.

Chitin Extracted from the Shell of Blue Swimming Crabs (Portunus pelagicus Linn.) Inhibits NF-kappaB p65 in Ethanol-Induced Gastric Ulcerative Wistar Rats

open access: yesMarine Drugs, 2023
Peptic ulcer disease is generated by the activation of NF-kappaB activity. A recent clinical study reported a significant increase in NF-kappaB2 gene expression in 79 samples of peptic ulcer patients compared to the control group.

Caspofungin-induced β(1,3)-glucan exposure in Candida albicans is driven by increased chitin levels

open access: yesmBio, 2023
To successfully induce disease, Candida albicans must effectively evade the host immune system. One mechanism used by C. albicans to achieve this is to mask immunogenic β(1,3)-glucan epitopes within its cell wall under an outer layer of mannosylated ...
