Serotonin Agents
|
D018490 |
[Drugs used for their effects on serotonergic systems. Among these are drugs that affect serotonin receptors, the life cycle of serotonin, and the survival of serotonergic neurons.
] |
|
Serotonin Antagonists
|
D012702 |
[Drugs that bind to but do not activate serotonin receptors, thereby blocking the actions of serotonin or SEROTONIN RECEPTOR AGONISTS.

|
Serotonin Plasma Membrane Transport Proteins
|
D050486 |
[A sodium chloride-dependent neurotransmitter symporter located on the PLASMA MEMBRANE of BLOOD PLATELETS. It transports SEROTONIN from the EXTRACELLULAR SPACE into the platelet CYTOPLASM.
, Sodium chloride-dependent neurotransmitter symporters located primarily on the PLASMA MEMBRANE of serotonergic neurons. They are different than SEROTONIN RECEPTORS, which signal cellular responses to SEROTONIN. They remove SEROTONIN from the EXTRACELLULAR SPACE by high affinity reuptake into PRESYNAPTIC TERMINALS. Regulates signal amplitude and duration at serotonergic synapses and is the site of action of the SEROTONIN UPTAKE INHIBITORS.

|
Serotonin Receptor Agonists
|
D017366 |
[Endogenous compounds and drugs that bind to and activate SEROTONIN RECEPTORS. Many serotonin receptor agonists are used as ANTIDEPRESSANTS; ANXIOLYTICS; and in the treatment of MIGRAINE DISORDERS.
] |
|
Serotonin Syndrome
|
D020230 |
[An adverse drug interaction characterized by altered mental status, autonomic dysfunction, and neuromuscular abnormalities. It is most frequently caused by use of both serotonin reuptake inhibitors and monoamine oxidase inhibitors, leading to excess serotonin availability in the CNS at the serotonin 1A receptor.
] |
|
Serotonin Uptake Inhibitors
|
D017367 |
[Compounds that specifically inhibit the reuptake of serotonin in the brain.
] |
|
Serotonin and Noradrenaline Reuptake Inhibitors
|
D000068760 |
[Drugs that selectively block or suppress the plasma membrane transport of SEROTONIN and NORADRENALINE into axon terminals and are used as ANTIDEPRESSIVE AGENTS.
] |
|
Serotyping
|
D012703 |
[Process of determining and distinguishing species of bacteria or viruses based on antigens they share.
] |
|
Serous Membrane
|
D012704 |
[A thin lining of closed cavities of the body, consisting of a single layer of squamous epithelial cells (MESOTHELIUM) resting on a thin layer of CONNECTIVE TISSUE, and covered with secreted clear fluid from blood and lymph vessels. Major serous membranes in the body include PERICARDIUM; PERITONEUM; and PLEURA.

|
Serpin E2
|
D058258 |
[A protease nexin and serpin subtype that is specific for several SERINE PROTEASES including UROKINASE; THROMBIN; TRYPSIN; and PLASMINOGEN ACTIVATORS.
] |
|
Serpins
|
D015843 |
[A family of serine proteinase inhibitors which are similar in amino acid sequence and mechanism of inhibition, but differ in their specificity toward proteolytic enzymes. Some members of the serpin family may be substrates rather than inhibitors of SERINE ENDOPEPTIDASES.
] |
|
Serrate-Jagged Proteins
|
D000072099 |
[Cell surface proteins that consist of multiple extracellular EPIDERMAL GROWTH FACTOR - like repeat sequences (EGF repeats), including calcium-binding EGF repeats. They function as transmembrane ligands for NOTCH RECEPTORS to control CELL DIFFERENTIATION during development.
] |
|
Serratia
|
D012705 |
[A genus of gram-negative, facultatively anaerobic, rod-shaped bacteria that occurs in the natural environment (soil, water, and plant surfaces) or as an opportunistic human pathogen.
] |
|
Serratia Infections
|
D016868 |
[Infections with bacteria of the genus SERRATIA.
] |
|
Serratia liquefaciens
|
D044090 |
[A species of gram-negative bacteria in the genus SERRATIA found in plants and the DIGESTIVE TRACT of rodents. It is the most prevalent Serratia species in the natural environment.
] |
|
Serratia marcescens
|
D012706 |
[A species of gram-negative, facultatively anaerobic, rod-shaped bacteria found in soil, water, food, and clinical specimens. It is a prominent opportunistic pathogen for hospitalized patients.
] |
|
Sertoli Cell Tumor
|
D012707 |
[Gonadal neoplasm composed entirely of SERTOLI CELLS or may have a component of GRANULOSA CELLS. Some of the Sertoli cell tumors produce ESTROGEN or ANDROGENS, but seldom in sufficient quantity to cause clinical symptoms such as FEMINIZATION or masculinization (VIRILISM).
] |
|
Sertoli Cell-Only Syndrome
|
D054331 |
[A type of male infertility in which no germ cells are visible in any of the biopsied SEMINIFEROUS TUBULES (type I) or in which germ cells are present in a minority of tubules (type II). Clinical features include AZOOSPERMIA, normal VIRILIZATION, and normal chromosomal complement.
] |
|
Sertoli Cells
|
D012708 |
[Supporting cells projecting inward from the basement membrane of SEMINIFEROUS TUBULES. They surround and nourish the developing male germ cells and secrete ANDROGEN-BINDING PROTEIN and hormones such as ANTI-MULLERIAN HORMONE. The tight junctions of Sertoli cells with the SPERMATOGONIA and SPERMATOCYTES provide a BLOOD-TESTIS BARRIER.
] |
|
Sertoli-Leydig Cell Tumor
|
D018310 |
[A sex cord-gonadal stromal tumor consists of LEYDIG CELLS; SERTOLI CELLS; and FIBROBLASTS in varying proportions and degree of differentiation. Most such tumors produce ANDROGENS in the Leydig cells, formerly known as androblastoma or arrhenoblastoma. Androblastomas occur in the TESTIS or the OVARY causing precocious masculinization in the males, and defeminization, or virilization (VIRILISM) in the females. In some cases, the Sertoli cells produce ESTROGENS.
