Extraction and partial purification for adhesive protein FimH from type-1 pili which isolated from uorpathogenic E.coli

مجلة بغداد للعلوم
    Type-1 fimbriae have been extracted from E.coli which was previously isolated, the yield was 2.8 mg fimbriae/10 g bacteria , the crude fimbriae was partially purified by several solubilization and recrystilization methods using a series of buffer ...

Immunoelectron microscopic analysis of elongation of type 1 fimbriae in Escherichia coli [PDF]

Journal of Bacteriology, 1987
Using 10- and 20-nm-diameter gold particles conjugated to an antifimbrial monoclonal antibody, we analyzed the location of assembly of newly formed subunits on growing type 1 fimbriae of Escherichia coli. Fimbriae were removed from an E. coli K-12-derived strain, CSH50, by blending.

Plant‐produced encapsulin displays non‐typhoidal Salmonella enterica antigens and assembles into mosaic nanoparticles

The FEBS Journal, EarlyView.
This study investigates the potential of encapsulin as an antigen display platform for the development of a candidate Salmonella vaccine for poultry. Encapsulin constructs were transiently expressed in Nicotiana benthamiana where they accumulated to high levels.

Location of Binding Sites on Common Type 1 Fimbriae from Escherichia coli [PDF]

Journal of General Microbiology, 1979
Common type 1 fimbriae were isolated from Escherichia coli and their length distribution profile was determined before and after treatment with ultrasound. As fimbriae were shortened, so their haemagglutinating capacity decreased, but their ability to bind to erythrocytes did not decrease to the same extent. Isolated fimbriae did not agglutinate inside-

Orchestrated molecular changes of proliferative, migratory‐fibrillar, synaptic, and postmigratory compartments align with precocious cortex‐type specification in the early human pallium

Journal of Anatomy, EarlyView.
Early human cortical development is organized by transient cellular compartments that define cortical types before mature layers form. Analysis of the human fetal pallium (7.5–15 PCW) shows distinct spatiotemporal trajectories for the archicortex, mesocortex, and neocortex, with delayed but accelerated differentiation in allocortical regions.

Inflammatory and Immunological Basis of Periodontal Diseases

Journal of Periodontal Research, EarlyView.
The periodontal lesion emerges as an evolving immunological battlefield, where host–microbiome interactions, dysregulated immune responses, fragile resolution mechanisms, and inflammophilic dysbiosis converge to shift the balance from homeostasis to unrestrained tissue destruction.

Analysis of Spleen-Induced Fimbria Production in Recombinant Attenuated Salmonella enterica Serovar Typhimurium Vaccine Strains

mBio, 2017
Salmonella enterica serovar Typhimurium genome encodes 13 fimbrial operons. Most of the fimbriae encoded by these operons are not produced under laboratory conditions but are likely to be synthesized in vivo.

Uropathogenic Escherichia coli P and Type 1 fimbriae act in synergy in a living host to facilitate renal colonization leading to nephron obstruction. [PDF]

PLoS Pathogens, 2011
The progression of a natural bacterial infection is a dynamic process influenced by the physiological characteristics of the target organ. Recent developments in live animal imaging allow for the study of the dynamic microbe-host interplay in real-time ...

Molecular Basis for the Enterocyte Tropism Exhibited bySalmonella typhimurium Type 1 Fimbriae [PDF]

Journal of Biological Chemistry, 1999
Salmonella typhimurium exhibits a distinct tropism for mouse enterocytes that is linked to their expression of type 1 fimbriae. The distinct binding traits of Salmonella type 1 fimbriae is also reflected in their binding to selected mannosylated proteins and in their ability to promote secondary bacterial aggregation on enterocyte surfaces.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...
