Ketamine is gaining ground as a potential treating depression because it has a distinct mode of action than typical drugs that influence monoamine neurotransmitters including noradrenaline, dopamine, or serotonin. Ketamine is thought to act by blocking N-methyl-d-aspartate (NMDA) receptors in the brain, which interact with the amino acid neurotransmitter glutamate. The resultant chemical changes in the brain caused by ketamine are not yet fully understood but could involve ketamine-induced gene expression and signaling cascades that act long after the drug has been eliminated from the body. Despite these remarkable effects, the widespread use of ketamine is limited by potential side effects including the emergence reactions (hallucinations, dreams, and out-of-body experiences) by recreational users, who need further study before long-term use of ketamine can be approved for depression. Thus, studies are necessary to further elucidate mechanistic actions of ketamine at cellular and network levels. Thus, we are exploring the involvement of molecular targets for the treatment and psychomimetic phenomena of the ketamine.

UI	MeSH Term	Description	Entries
D007649	Ketamine	A cyclohexanone derivative used for induction of anesthesia. Its mechanism of action is not well understood, but ketamine can block NMDA receptors (RECEPTORS, N-METHYL-D-ASPARTATE) and may interact with sigma receptors.	2-(2-Chlorophenyl)-2-(methylamino)cyclohexanone,CI-581,Calipsol,Calypsol,Kalipsol,Ketalar,Ketamine Hydrochloride,Ketanest,Ketaset,CI 581,CI581
D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon
D003863	Depression	Depressive states usually of moderate intensity in contrast with MAJOR DEPRESSIVE DISORDER present in neurotic and psychotic disorders.	Depressive Symptoms,Emotional Depression,Depression, Emotional,Depressive Symptom,Symptom, Depressive
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000778	Anesthetics, Dissociative	Intravenous anesthetics that induce a state of sedation, immobility, amnesia, and marked analgesia. Subjects may experience a strong feeling of dissociation from the environment. The condition produced is similar to NEUROLEPTANALGESIA, but is brought about by the administration of a single drug. (From Gilman et al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed)	Dissociative Anesthetics
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D015398	Signal Transduction	The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
