The hydrophobicities of cholera toxin, tetanus toxin and their components [PDF]

Biochemical Journal, 1981
1. Charge-shift electrophoresis showed that cholera toxin and its subunits have no hydrophobic surfaces. 2. Amino-acid composition and sequence data suggested that the proteins have no masked hydrophobic regions. 3. The A subunit of cholera toxin may interact with polar molecules in the membrane to exert its effect inside the cell. 4.

Vibrio Pathogenicity Island-1: The Master Determinant of Cholera Pathogenesis

Frontiers in Cellular and Infection Microbiology, 2020
Cholera is an acute secretory diarrhoeal disease caused by the bacterium Vibrio cholerae. The key determinants of cholera pathogenicity, cholera toxin (CT), and toxin co-regulated pilus (TCP) are part of the genome of two horizontally acquired Mobile ...

Peanut‐Specific IgG4 mAbs Promote Regulatory Immune Responses Ex Vivo and Improve Oral Immunotherapy in Mice

Clinical &Experimental Allergy, EarlyView.
Allergen‐specific IgG4 mAbs were shown to block facilitated IgE binding to B cells and redirect allergens towards myeloid APC, leading to increased IL‐10 production in vitro. In combination with oral AIT, the mAbs inhibited mast cell activation and sustained allergen‐specific IgG4 levels in an in vivo model of peanut allergy. ABSTRACT Background Peanut

Rethinking diabetic retinopathy: Homeostatic mechanisms for retinal clearance

Diabetic Medicine, EarlyView.
In the healthy retina, balanced production and clearance of metabolic waste and fluid maintain retinal homeostasis and normal visual function. Diabetes disrupts this balance, increasing the accumulation of metabolic waste products, including advanced glycation end products (AGEs) and advanced lipoxidation end products (ALEs), while impairing waste and ...

Molecular insights into the evolutionary pathway of Vibrio cholerae O1 atypical El Tor variants.

PLoS Pathogens, 2014
Pandemic V. cholerae strains in the O1 serogroup have 2 biotypes: classical and El Tor. The classical biotype strains of the sixth pandemic, which encode the classical type cholera toxin (CT), have been replaced by El Tor biotype strains of the seventh ...

Phenotypic Florfenicol Resistance in floR‐Harbouring Flavobacterium psychrophilum Isolates (CC‐ST90): A Case Study From Danish Freshwater Rainbow Trout Aquaculture

Journal of Fish Diseases, EarlyView.
ABSTRACT Monitoring antimicrobial resistance (AMR) in fish pathogens is essential for supporting sustainable aquaculture. In this study, susceptibility testing and genome sequencing were used to characterize the AMR profile of seven Flavobacterium psychrophilum originating from Danish rainbow trout farms (2019–2022).
