GABA receptors are a class of receptors that respond to the neurotransmitter gamma-aminobutyric acid (GABA), the chief inhibitory neurotransmitter in the vertebrate central nervous system. There are two classes of GABA receptors: GABAA and GABAB. GABAA receptors are ligand-gated ion channels (also known as ionotropic receptors), whereas GABAB receptors are G protein-coupled receptors (also known asmetabotropic receptors). It has long been recognized that the fast response of neurons to GABA that is blocked by bicuculline and picrotoxin is due to direct activation of an anion channel. This channel was subsequently termed the GABAA receptor. Fast-responding GABA receptors are members of family of Cys-loop ligand-gated ion channels. A slow response to GABA is mediated by GABAB receptors, originally defined on the basis of pharmacological properties.

Creatinine serum levels correlate with muscle mass, glomerular filtration rate, and extrarenal clearance, serving as an evaluation biomarker for renal function, muscle mass, and clinical outcomes, and used for perioperative renal risk assessment. In addition, Creatinine can induce specific Cryptococcus species to produce creatinine deiminase and act as their nitrogen source, while it can be secreted via renal tubules. Creatinine is widely used in research related to various diseases such as neurodegenerative diseases, psychiatric disorders, acute kidney injury, chronic kidney disease, and renal failure.
