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.

Scanning microcalorimetric and circular dichroism studies of the normal and mutant flagellins of Salmonella suggest that they have a multidomain structure in common. Flagellin polymers (flagella) are depolymerized irreversibly into monomers as the temperature is raised, and the monomers undergo denaturation reversibly when cooled and heated again.

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 ...

Structural organization of flagellin
Journal of Molecular Biology, 1990The terminal regions of flagellin from Salmonella typhimurium have been reported to be disordered in solution, whereas the central part of the molecule contains protease-resistant, compact structural units. Here, conformational properties of flagellin and its proteolytic fragments were investigated and compared to characterize the domain organization ...

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 ...

Purification and chemical properties of flagellin
Archives of Biochemistry and Biophysics, 1959Abstract A study of flagella and flagellin from six bacterial species led to the following generalizations: Flagella consist of proteins that, after removal from the cell bodies by shaking, can be isolated in highly purified condition by fractional centrifugation, or a combination of centrifugation and fractional precipitation with ammonium sulfate ...

Flagellin as an object for supramolecular engineering
"Protein Engineering, Design and Selection", 1990A model of tertiary and quaternary structure of E. coli flagellin is suggested. According to this model, the molecule consists of two independent parts. One of them is formed by the N- and C-terminal regions of the polypeptide chain and is responsible for polymerization properties.

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 ...

Ten antisera raised in rabbits, against polymeric flagellins from ten different Salmonella serotypes were used to determine the relative cross-activities between salmonella flagellins in monomeric form. The results showed a high degree of cross-reactivity between the antisera (IgG antibodies) and all monomeric flagellins investigated.
