Bacterial flagellin—a potent immunomodulatory agent [PDF]
Experimental and Molecular Medicine, 2017 Flagellin is a subunit protein of the flagellum, a whip-like appendage that enables bacterial motility. Traditionally, flagellin was viewed as a virulence factor that contributes to the adhesion and invasion of host cells, but now it has emerged as a potent immune activator, shaping both the innate and adaptive arms of immunity during microbial ...

Sequential polymerization of flagellin A and flagellin B into Caulobacter flagella
Journal of Molecular Biology, 1981The mode of polymerization of two species of flagellins, flagellin A and flagellin B, in polar flagella of Caulobacter crescentus was examined. By immunological staining we found that 1 to 1.2 μm of the portion of the flagellar filament proximal to the cell was composed of flagellin B, whereas about 5 μm of the distal portion was composed of flagellin ...

Purification of Native Flagellin
2019Flagella are effective organelles of locomotion and one of several virulence factors in Proteus mirabilis. To study their properties and role in virulence, we describe a protocol to extract and purify the native flagellin of P. mirabilis. Purified flagellin can be visualized by SDS-PAGE or immunoblot and is suitable for downstream applications such as ...

Flagellin Signalling in Plant Immunity
2007Like all higher living organisms, plants are constantly exposed to microbes that either grow epiphytically on the organ surface, establish beneficial interactions in specific tissues, or infect host tissues as pathogens and cause disease. In order to infect, pathogens must attach to the plant surface and break physical barriers to enter the tissue ...

Flagellin maintains eosinophils in the intestine
Cytokine, 2022Eosinophils (Eos) are the major effector cells in allergic response. The regulation of Eo is not fully understood yet. Flagellin (FGN) has immune regulatory functions. This study aims to elucidate the role of FGN in maintaining Eo at the static status in the intestinal tissues. A mouse food allergy (FA) model was developed.

Science's STKE, 2001
Immune responses to flagellin have been evolutionarily conserved between plants and animals. In Arabidopsis , FLS2, a leucine-rich repeat (LRR) domain containing serine-threonine transmembrane kinase binds bacterial flagellin and mediates signals, culminating in a defensive response. Gómez-Gómez et al.

Hayashi et al. characterized the transmembrane Toll-like receptor (TLR) 5 protein and identified a physiologically relevant ligand capable of activating TLR5 signaling. Overexpression of chimeric proteins consisting of the intracellular domain of TLR5 fused to the extracellular domain of CD4 (to promote dimerization)

Relatedness of the flagellins from methanogens
Archives of Microbiology, 1992Purified flagellar filaments isolated from six methanogens were composed of multiple flagellins. Two flagellins were present in Methanococcus deltae (Mr = 34,000 and 32,000), Methanoculleus marisnigri (Mr = 31,000 and 25,500) and Methanococcus jannaschii (Mr = 31,000 and 27,500), three in Methanothermus fervidus (Mr = 34,000, 25,000 and 24,000) and ...

Characterization of flagellin from Clostridium chauvoei
Veterinary Microbiology, 1999Differential centrifugation and cesium chloride-equilibrium centrifugation were used to purify the flagella from the strain Okinawa of the formalin-fixed Clostridium chauvoei. SDS-PAGE profile of purified flagella showed that a major protein band with a molecular mass of 46 kDa, corresponding to the flagellin monomer, and at least two minor protein ...
