Procedimiento general para purificar a pequeña escala las fimbrias expresadas por cepas porcinas de Escherichia coli enterotoxigénicas

Revista Colombiana de Biotecnología, 2008
La fimbriación en cepas de Escherichia coli enterotoxigénicas es un proceso complejo controlado por varios mecanismos: reguladores globales y locales de la transcripción y el control postranscripcional, e influenciado por factores como velocidad de ...

Lipid-Mediated In Vivo Gene Transfer Replaces the Loss of Choline Acetyltransferase Activity after Unilateral Fimbria-Fornix Aspiration

Cell Transplantation, 2001
In Alzheimer's disease cholinergic neurons degenerate, resulting in loss of hippocampal acetylcholine. The fimbria-fornix aspiration is a well-known animal model mimicking hippocampal cholinergic deficiency.

Recurrent outflow obstruction of a choked catheter for peritoneal dialysis caused by a fallopian tube fimbria in a five-month-old female

Journal of Pediatric Surgery Case Reports, 2022
Outflow obstruction of a catheter for peritoneal dialysis (PD) is one of the most common complications in patients who are undergoing PD for renal failure.

SssP1, a Streptococcus suis Fimbria-Like Protein Transported by the SecY2/A2 System, Contributes to Bacterial Virulence

Applied and Environmental Microbiology, 2018
Streptococcus suis is an important zoonotic pathogen. Here, we managed to identify key factors to clarify the virulence of S. suis strain CZ130302 from a novel serotype, Chz. Notably, it was shown that a fimbria-like structure was significantly connected

The Non-Fimbriate Phenotype Is Predominant among Salmonella enterica Serovar Choleraesuis from Swine and Those Non-Fimbriate Strains Possess Distinct Amino Acid Variations in FimH.

PLoS ONE, 2016
Although most Salmonella serovars are able to infect a range of animal hosts, some have acquired the ability to cause systemic infections of specific hosts.

Proteus mirabilis fimbriae: identification, isolation, and characterization of a new ambient-temperature fimbria [PDF]

Infection and Immunity, 1994
Urinary tract infections involving Proteus mirabilis may lead to complications including bladder and kidney stones, acute pyelonephritis, and bacteremia. This bacterium produces a number of fimbriae, two of which, MR/P fimbria and P. mirabilis fimbria, have been shown to contribute to the ability of this pathogen to colonize the bladder and kidney.

Taurocholic Acid Is Associated With Disturbed Functional Connectivity in the Hippocampus of Patients With Depression

Advanced Science, EarlyView.
This study identifies elevated taurocholic acid (TCA) in Major Depressive Disorder patients. Gut microbiome‐associated TCA impairs hippocampal neurogenesis, triggers microglia activation, and elicits depression‐like behavior in mice via the S1PR2. In patients, functional neuroimaging reveals that serum TCA levels correlate with altered functional ...

NAD⁺ Reduction in Glutamatergic Neurons Induces Lipid Catabolism and Neuroinflammation in the Brain via SARM1

Advanced Science, EarlyView.
NAD⁺ homeostasis maintains neuronal integrity through opposing actions of NMNAT2 and SARM1. Loss of NMNAT2 in glutamatergic neurons reprograms cortical metabolism from glucose to lipid catabolism, depletes lipid stores, and triggers inflammation and neurodegeneration.

Caracterização da virulência da cepa de Escherichia coli - BK99 [PDF]

Ciência Rural, 2001
Com o objetivo de identificar a patogenicidade e resistência a antimicrobianos da cepa de E. coli BK99, foram utilizados alguns testes: aglutinação em lâmina para detecção da fímbria F5, produção de STa, ensaios para hemolisinas e colicinas ...

Exogenous Leukemia Inhibitory Factor Stimulates Oligodendrocyte Progenitor Cell Proliferation and Enhances Hippocampal Remyelination [PDF]

, 2012
New CNS neurons and glia are generated throughout adulthood from endogenous neural stem and progenitor cells. These progenitors can respond to injury, but their ability to proliferate, migrate, differentiate, and survive is usually insufficient to ...
