The chloride ion is the anion (negatively charged ion) Cl−.
Cholera is an infection of the small intestine by some strains of the bacterium Vibrio cholerae.
The CTXφ bacteriophage is a filamentous bacteriophage that contains the genetic material needed by the Vibrio cholerae bacterium for the production of cholera toxin, or CT.
Cyclic adenosine monophosphate (cAMP, cyclic AMP, or 3',5'-cyclic adenosine monophosphate) is a second messenger important in many biological processes.
Cystic fibrosis transmembrane conductance regulator (CFTR) is a membrane protein and chloride channel in vertebrates that is encoded by the CFTR gene.
In physiology, dehydration is a deficit of total body water, with an accompanying disruption of metabolic processes.
In chemistry, a disulfide refers to a functional group with the structure R−S−S−R′.
Endocytosis is a form of bulk transport in which a cell transports molecules (such as proteins) into the cell (endo- + cytosis) by engulfing them in an energy-using process.
An enterotoxin is a protein exotoxin released by a microorganism that targets the intestines.
Enzymes are macromolecular biological catalysts.
ER oxidoreductin 1 (Ero1) is an oxidoreductase enzyme that catalyses the formation and isomerization of protein disulfide bonds in the endoplasmic reticulum (ER) of eukaryotes.
Escherichia coli (also known as E. coli) is a Gram-negative, facultatively anaerobic, rod-shaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms (endotherms).
An exotoxin is a toxin secreted by bacteria.
G proteins, also known as guanine nucleotide-binding proteins, are a family of proteins that act as molecular switches inside cells, and are involved in transmitting signals from a variety of stimuli outside a cell to its interior.
A ganglioside is a molecule composed of a glycosphingolipid (ceramide and oligosaccharide) with one or more sialic acids (e.g. n-acetylneuraminic acid, NANA) linked on the sugar chain.
Gi alpha subunit (Gαi, or Gi/G0 or Gi protein) is a heterotrimeric G protein subunit that inhibits the production of cAMP from ATP.
GM1 (monosialotetrahexosylganglioside) the "prototype" ganglioside, is a member of the ganglio series of gangliosides which contain one sialic acid residue.
The Gs alpha subunit (Gαs, Gsα, or Gs protein) is a heterotrimeric G protein subunit that activates the cAMP-dependent pathway by activating adenylyl cyclase.
Heat-labile enterotoxin is a type of labile toxin found in Escherichia coli and Bacillus cereus.
The STAT3-Ser/Hes3 signaling axis is a specific type of intracellular signaling pathway that regulates several fundamental properties of cells.
A histochemical tracer is a compound used to reveal the location of cells and track neuronal projections.
Horizontal gene transfer (HGT) or lateral gene transfer (LGT) is the movement of genetic material between unicellular and/or multicellular organisms other than by the ("vertical") transmission of DNA from parent to offspring.
An ion is an atom or molecule that has a non-zero net electrical charge (its total number of electrons is not equal to its total number of protons).
The plasma membranes of cells contain combinations of glycosphingolipids and protein receptors organised in glycolipoprotein microdomains termed lipid rafts.
In biology, a lumen (plural lumina) is the inside space of a tubular structure, such as an artery or intestine.
Nicotinamide adenine dinucleotide (NAD) is a coenzyme found in all living cells.
An oligomer (oligo-, "a few" + -mer, "parts") is a molecular complex of chemicals that consists of a few monomer units, in contrast to a polymer, where the number of monomers is, in principle, infinite.

A protein complex or multiprotein complex is a group of two or more associated polypeptide chains.
Protein disulfide isomerase, or PDI, is an enzyme in the endoplasmic reticulum (ER) in eukaryotes and the periplasm of bacteria that catalyzes the formation and breakage of disulfide bonds between cysteine residues within proteins as they fold.
In cell biology, protein kinase A (PKANot to be confused with pKa, the symbol for the acid dissociation constant.) is a family of enzymes whose activity is dependent on cellular levels of cyclic AMP (cAMP).
Protein primary structure is the linear sequence of amino acids in a peptide or protein.
