Inborn errors of immunity in children with neuroinflammation

Developmental Medicine &Child Neurology, EarlyView.
Abstract Inborn errors of immunity (IEIs), an expanding group of monogenic disorders with diverse clinical manifestations, are increasingly recognized to include neuroinflammatory disease. Examples of diseases included under this umbrella are Aicardi–Goutières syndrome, deficiency of adenosine deaminase 2, familial haemophagocytic lymphohistiocytosis ...

Purification and Characterization of Shiga Toxin 2f, an Immunologically Unrelated Subtype of Shiga Toxin 2

PLoS ONE, 2013
Shiga-like toxin 2 (Stx2) is one of the most important virulence factors in enterohaemorrhagic Escherichia coli (E. coli) strains such as O157H7. Subtypes of Stx2 are diverse with respect to their sequence, toxicity, and distribution. The most diverse Stx2 subtype, Stx2f, is difficult to detect immunologically, but is becoming more frequently ...

OPPORTUNICTIC ENTEROBACTERIACAE AS THE CAUSE OF THE ACUTE DIARRHEA AND GUT DISBIOSIS

Инфекция и иммунитет, 2014
. Strains of Klebsiella pneumonia isolated from faces were studied to detect virulence factors of “classical” enteric pathogens causing acute diarrhea (Shigella, Salmonella, diarreagenic Escherichia coli). We haven’t detect in Klebsiella the genes encode

A new branch of mammalian vitamin B6 metabolism: AKR1C‐mediated conversion of pyridoxal to pyridoxine and 4‐pyridoxolactone

The FEBS Journal, EarlyView.
Pyridoxal 5′‐phosphate (PLP) homeostasis relies on salvage enzymes, yet key metabolic branches remain undefined. We identify AKR1C isozymes as previously undescribed contributors that convert pyridoxal into pyridoxine or 4‐pyridoxolactone through reductase and dehydrogenase activities.

Iloperidone treatment mitigates the Juvenile Huntington's Disease phenotype possibly via Sigma‐1 Receptor Modulation

The FEBS Journal, EarlyView.
We investigated the potential of iloperidone as an activator of Sigma‐1 receptor (S1R) neuroprotective function in juvenile Huntington's disease (jHD). We tested iloperidone on cortical neurons differentiated from patient‐derived iPSCs, demonstrating that it acts as a S1R agonist, decreasing apoptosis, huntingtin aggregation, and oxidative stress ...

Ligand binding represses bacterial histidine kinase activity by inhibiting its dimerization

The FEBS Journal, EarlyView.
PdtaS is a kinase in the pathogen Mycobacterium tuberculosis that senses copper and nitric oxide and controls virulence gene expression, but how the kinase senses these compounds was unclear. We show that PdtaS is active as a dimer with each monomer phosphorylating the other in trans.

UV-Sensitivity of Shiga Toxin-Converting Bacteriophage Virions Φ24B, 933W, P22, P27 and P32

Toxins, 2015
Shiga toxin-converting bacteriophages (Stx phages) are present as prophages in Shiga toxin-producing Escherichia coli (STEC) strains. Theses phages can be transmitted to previously non-pathogenic E.

The Interplay of M1 Macrophages and Dental Pulp Stem Cells Promotes Angiogenesis Through IL‐8‐Dependent VEGF Regulation: An In Vitro Study

International Endodontic Journal, EarlyView.
ABSTRACT Background Dental pulp inflammation triggers immune responses involving macrophages and dental pulp stem cells (DPSCs), which interact to regulate angiogenesis essential for tissue repair. M1 pro‐inflammatory macrophages predominate early in pulpitis, and clarifying their angiogenic role is vital in identifying inflammatory regenerative ...

STUDIES ON THE TOXIN PRODUCTION OF THE SHIGA BACILLI [PDF]

Journal of Experimental Medicine, 1936
1. The S, R, and Rn variants of the Shiga bacillus are equally toxic. 2. The effect of the toxin upon rabbits is the same, whether it is derived from filtrates of broth cultures (3 to 6 days old), or is obtained by autolysis of the killed bacteria, grown on agar surface.

Identification of Novel Therapeutic Agent Candidates Through High Throughput Screening With Chemical Library Based on Molecular Subclassification in Canine Histiocytic Sarcoma Cell Lines

Veterinary and Comparative Oncology, EarlyView.
ABSTRACT Effective chemotherapy for canine histiocytic sarcoma (CHS) has yet to be established. In our previous study, CHS cell lines were subclassified into two groups based on their gene expression profiles: Group A and Group B. This study aimed to identify novel therapeutic agents that are effective against each CHS subgroup, and we performed high ...
