The endogenous ligands for opioid receptors in mammals include three families of peptides, the enkephalins, endorphins, and dynorphins. The receptor classes include mu, delta, and kappa receptors. Sigma receptors bind several psychoactive substances, including certain opioids, but their endogenous ligands are not known.Mice, Knockout: Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.Receptor, Angiotensin, Type 1: An angiotensin receptor subtype that is expressed at high levels in a variety of adult tissues including the CARDIOVASCULAR SYSTEM, the KIDNEY, the ENDOCRINE SYSTEM and the NERVOUS SYSTEM. Activation of the type 1 angiotensin receptor causes VASOCONSTRICTION and sodium retention.QuinuclidinesAdrenergic Antagonists: Drugs that bind to but do not activate ADRENERGIC RECEPTORS. Adrenergic antagonists block the actions of the endogenous adrenergic transmitters EPINEPHRINE and NOREPINEPHRINE.Receptors, Histamine H3: A class of histamine receptors discriminated by their pharmacology and mode of action. Histamine H3 receptors were first recognized as inhibitory autoreceptors on histamine-containing nerve terminals and have since been shown to regulate the release of several neurotransmitters in the central and peripheral nervous systems. (From Biochem Soc Trans 1992 Feb;20(1):122-5)Synapses: Specialized junctions at which a neuron communicates with a target cell. At classical synapses, a neuron's presynaptic terminal releases a chemical transmitter stored in synaptic vesicles which diffuses across a narrow synaptic cleft and activates receptors on the postsynaptic membrane of the target cell. The target may be a dendrite, cell body, or axon of another neuron, or a specialized region of a muscle or secretory cell. Neurons may also communicate via direct electrical coupling with ELECTRICAL SYNAPSES. Several other non-synaptic chemical or electric signal transmitting processes occur via extracellular mediated interactions.Adrenergic beta-2 Receptor Antagonists: Drugs that bind to and block the activation of ADRENERGIC BETA-2 RECEPTORS.Imidazoles: Compounds containing 1,3-diazole, a five membered aromatic ring containing two nitrogen atoms separated by one of the carbons.

Distinguish from 1,2-diazole (PYRAZOLES).Mineralocorticoid Receptor Antagonists: Drugs that bind to and block the activation of MINERALOCORTICOID RECEPTORS by MINERALOCORTICOIDS such as ALDOSTERONE.Receptors, Opioid, mu: A class of opioid receptors recognized by its pharmacological profile. Mu opioid receptors bind, in decreasing order of affinity, endorphins, dynorphins, met-enkephalin, and leu-enkephalin. They have also been shown to be molecular receptors for morphine.Viper Venoms: Venoms from SNAKES of the viperid family. They tend to be less toxic than elapid or hydrophid venoms and act mainly on the vascular system, interfering with coagulation and capillary membrane integrity and are highly cytotoxic. They contain large amounts of several enzymes, other factors, and some toxins.Glycine: A non-essential amino acid. It is found primarily in gelatin and silk fibroin and used therapeutically as a nutrient. It is also a fast inhibitory neurotransmitter.Animals, Newborn: Refers to animals in the period of time just after birth.Membrane Potentials: The voltage differences across a membrane. For cellular membranes they are computed by subtracting the voltage measured outside the membrane from the voltage measured inside the membrane. They result from differences of inside versus outside concentration of potassium, sodium, chloride, and other ions across cells' or ORGANELLES membranes. For excitable cells, the resting membrane potentials range between -30 and -100 millivolts. Physical, chemical, or electrical stimuli can make a membrane potential more negative (hyperpolarization), or less negative (depolarization).CHO Cells: CELL LINE derived from the ovary of the Chinese hamster, Cricetulus griseus (CRICETULUS). The species is a favorite for cytogenetic studies because of its small chromosome number. The cell line has provided model systems for the study of genetic alterations in cultured mammalian cells.6-Cyano-7-nitroquinoxaline-2,3-dione: A potent excitatory amino acid antagonist with a preference for non-NMDA iontropic receptors.

Four of the more common genera are Cricetus, CRICETULUS; MESOCRICETUS; and PHODOPUS.Cell Line: Established cell cultures that have the potential to propagate indefinitely.Receptors, Corticotropin-Releasing Hormone: Cell surface proteins that bind corticotropin-releasing hormone with high affinity and trigger intracellular changes which influence the behavior of cells. The corticotropin releasing-hormone receptors on anterior pituitary cells mediate the stimulation of corticotropin release by hypothalamic corticotropin releasing factor. The physiological consequence of activating corticotropin-releasing hormone receptors on central neurons is not well understood.Muscle Contraction: A process leading to shortening and/or development of tension in muscle tissue. Muscle contraction occurs by a sliding filament mechanism whereby actin filaments slide inward among the myosin filaments.Kinetics: The rate dynamics in chemical or physical systems.Antihypertensive Agents: Drugs used in the treatment of acute or chronic vascular HYPERTENSION regardless of pharmacological mechanism.

It has mild hypnotic properties and some local anesthetic action and is used for allergies (including skin eruptions) both parenterally and locally. It is a common ingredient of cold remedies.Receptors, Serotonin, 5-HT4: A subtype of G-protein-coupled SEROTONIN receptors that preferentially couple to GS STIMULATORY G-PROTEINS resulting in increased intracellular CYCLIC AMP. Several isoforms of the receptor exist due to ALTERNATIVE SPLICING of its mRNA.PhenylpropionatesReceptor, Bradykinin B2: A constitutively expressed subtype of bradykinin receptor that may play a role in the acute phase of the inflammatory and pain response. It has high specificity for intact forms of BRADYKININ and KALLIDIN. The receptor is coupled to G-PROTEIN, GQ-G11 ALPHA FAMILY and G-PROTEIN, GI-GO ALPHA FAMILY signaling proteins.Receptors, Bombesin: Cell surface proteins that bind bombesin or closely related peptides with high affinity and trigger intracellular changes influencing the behavior of cells.

- Memory impairment due to alcohol has been linked to disruption of hippocampal function-in particular affecting gamma-Aminobutyric acid (GABA) and N-methyl-D-aspartate (NMDA) neurotransmission which negatively impacts long-term potentiation (LTP). (wikipedia.org)
- At higher doses, ethanol also affects NMDA receptors (NMDARs) by inhibiting the ion current induced by NMDA, a glutamate receptor agonist. (wikipedia.org)
- Antagonism of NMDA or AMPA receptors with ketamine, dizocilpine, or NBQX during later challenges with alcohol were largely serenic without having any notable impact on the expression of alcohol-escalated rates of FI responding. (frontiersin.org)
- What are NMDA receptors? (healthtap.com)
- Most of the clinical effects can be explained by the interaction of ethanol with various neurotransmitters and neuroreceptors in the brain, including those interacting with gamma-aminobutyric acid (GABA), glutamate (NMDA), and opiates. (medscape.com)
- 1997 ) demonstrated that fyn phosphorylation of the NR2B subunit is necessary for the development of acute tolerance to alcohol's inhibitory effects on NMDA receptor-mediated currents in hippocampal neurons. (aspetjournals.org)
- Thus, the available evidence suggests that deletion of the fyn-kinase gene may, in addition to the NMDA receptor, interact with the GABA A receptor. (aspetjournals.org)
- 6 reported that coadministration of an N -methyl-d-aspartate (NMDA) receptor antagonist with γ-aminobutyric acid type A (GABA A ) receptor agonists synergistically potentiated neonatal brain cell death and resulted in functional deficits in adult mice, although the underlying mechanism is not fully understood. (asahq.org)
- The most thoroughly investigated drug that has NMDA antagonist and GABA A agonist property is ethanol, which induces fetal alcohol syndrome if the fetus is exposed during the brain growth spurt. (asahq.org)
- 8 Sevoflurane has been shown to enhance GABA A receptors 9 and block NMDA receptors, although more research is necessary to better characterize its effects on NMDA receptors. (asahq.org)
- Ethanol also acts as an antagonist at the NMDA receptor . (howstuffworks.com)
- NMDA is a receptor for glutamaine , a neurotransmitter responsible for passing messages from one nerve cell to another. (howstuffworks.com)
- When the NMDA receptor is activated, it enhances stimulation of the nervous system. (howstuffworks.com)
- Alcohol also inhibits NMDA receptors, which are part of a general excitatory signalling circuit, so a second ingredient of the alcohol substitute would be an NMDA antagonist such as dizoclipine, originally developed as a drug for stroke. (drugs-forum.com)
- Drug companies have been working on new glutamate-modulating antianxiety drugs, and a glutamate-active drug called acamprosate, which works by occupying sites on glutamate (NMDA) receptors, has found limited use as a drug for alcohol withdrawal after dozens of clinical trials. (blogspot.com)
