Photolabelling of cholera toxin by NAD+ [PDF]

Biochemical Journal, 1987
When cholera toxin is incubated under u.v. light with NAD+ labelled in either the adenine or the nicotinamide moiety, radioactivity becomes covalently bound to the protein. The reaction is specific for cholera toxin, and is inhibited by excess unlabelled NAD+ or NAD analogues. Only the active A 1 chain of the toxin is labelled.

Comparison of Receptor‐Mediated Endocytosis and Its Application to Enhance DNA Transfection by TFAMoplex

Advanced NanoBiomed Research, Volume 6, Issue 8, August 2026.
We developed an assay to distinguish cellular binding from internalization. Compatible with microscopy and high‐throughput screening, the method identifies ligand‐mediated uptake. Applying top candidates to a protein‐based DNA carrier enhanced transfection efficiency, providing a rational strategy to improve non‐viral gene delivery systems.

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.

Gamma Delta T Cells in Shrimp Allergy Express a Unique Cytotoxic Cytokine Profile

Clinical and Translational Allergy, Volume 16, Issue 8, August 2026.
ABSTRACT Shellfish allergy is the most common food allergy in adults and the third most common in children. γδ T cells have been identified as playing a critical role in antigen tolerance in allergic diseases in mouse models. In humans, γδ T cells may play a regulatory role in peanut immunotherapy, and their role in shrimp allergy remains unclear.

An Olfactory Piriform Cortex‐Lateral Hypothalamus Neural Circuit Contributes to Linalool‐Induced Analgesia

CNS Neuroscience &Therapeutics, Volume 32, Issue 8, August 2026.
Linalool odor exposure activates a glutamatergic projection from the piriform cortex to the lateral hypothalamus (PiriGlu‐LH), mediating descending inhibitory pain pathways. This demonstrates a novel neural mechanism for olfactory‐induced pain modulation and suggests potential therapeutic implications for pain management.

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 ...
