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

, 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.

Characterization of Early, Chitin-Induced Gene Expression in Arabidopsis

Molecular Plant-Microbe Interactions, 2002
Three genes (i.e., a zinc finger protein, a lectin-like protein, and AtMPK3), previously shown to respond to chitin elicitation in microarray experiments, were used to examine the response of Arabidopsis spp. to chitin addition. Maximum induction for all

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

Frontiers 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.

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

PLoS 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.

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

PLoS 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.

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

Marine 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

mBio, 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 ...

A secreted LysM effector protects fungal hyphae through chitin-dependent homodimer polymerization.

PLoS Pathogens, 2020
Plants trigger immune responses upon recognition of fungal cell wall chitin, followed by the release of various antimicrobials, including chitinase enzymes that hydrolyze chitin.

Nanofibrillation is an Effective Method to Produce Chitin Derivatives for Induction of Plant Responses in Soybean

Plants, 2020
Chitin, an N-acetylglucosamine polymer, is well-known to have unique biological functions, such as growth promotion and disease resistance induction in plants.

The cloning , expression and characterisation of bacterial chitin-binding proteins from pseudomonas aeruginosa , serratia marcescens, photorhabdus luminescens and photorhabdus asymbiotica. [PDF]

, 2011
It is well recognised that most proteins are subject to post translational modifications and that these modifications can have specific effects on the biological properties and functions of these proteins.
