Purification and characterization of a novel secondary fimbrial protein from Porphyromonas gulae

Journal of Oral Microbiology, 2012
Background: Porphyromonas gulae are black-pigmented anaerobic bacteria isolated from the gingival sulcus of various animal hosts and are distinct from Porphyromonas gingivalis originating in humans. We previously reported the antigenic similarities of 41-

Expression of Bordetella pertussis Antigens Fused to Different Vectors and Their Effectiveness as Vaccines

Vaccines, 2021
Pertussis is an acute respiratory tract infection caused by Bordetella pertussis. Even though its current vaccine coverage is relatively broad, they still have some shortcomings such as short protection time and might be incapable of blocking the spread ...

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.

Transcriptional Profiling of a Cross-Protective Salmonella enterica serovar Typhimurium UK-1 dam Mutant Identifies a Set of Genes More Transcriptionally Active Compared to Wild-Type, and Stably Transcribed across Biologically Relevant Microenvironments

Pathogens, 2014
Vaccination with Salmonella enterica serovar Typhimurium lacking DNA adenine methyltransferase confers cross-protective immunity against multiple Salmonella serotypes. The mechanistic basis is thought to be associated with the de-repression of genes that

FimH and Type 1 Pili Mediated Tumor Cell Cytotoxicity by Uropathogenic Escherichia coli In Vitro

Pathogens, 2023
Uropathogenic Escherichia coli express hairlike proteinaceous surface projections, known as chaperone–usher pathway (CUP) pili. Type 1 pili are CUP pili with well-established pathogenic properties. The FimH adhesin subunit of type 1 pili plays a key role

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.

Generating golden Syrian hamsters with conditional alleles via zygote microinjection of CRISPR/Cas9

Animal Models and Experimental Medicine, EarlyView.
We established the first conditional knockout (cKO) model in the golden Syrian hamster by CRISPR/Cas9‐mediated genome editing. Cas9 protein, two sgRNAs, and a donor plasmid carrying loxP‐flanked exon 2 of the ApoF gene were microinjected into one‐cell embryos. The floxed allele was efficiently generated (up to 27%) and transmitted through the germline.

Anatomical Progression of Neuropathology in FTLD‐TDP Type C and Linkage to Annexin A11

Annals of Neurology, EarlyView.
Objective Frontotemporal lobar degenerations (FTLD)‐TDP type C (TDP‐C) is distinguished from other FTLD‐TDP subtypes by 3 unique features: (1) invariable onset in the anterior temporal lobe (ATL), (2) phosphorylated TDP‐43 (pTDP) neurites in cortex, and (3) colocalization of all pTDP deposits with annexin A11 (ANXA11).
