Adrenergic receptor autoantibodies The adrenergic receptors (or adrenoreceptors) are a class of cell membrane-bound protein receptors throughout the body that are targets of the catecholamines , especially norepinephrine (or noradrenaline) and epinephrine (or adrenaline).
Autoantibody tests may be ordered as part of an investigation of chronic progressive arthritis type symptoms and/or unexplained fevers, fatigue, muscle weakness and rashes. The antinuclear antibody (ANA) test is often ordered first. ANA is a marker of the autoimmune process – it is positive with a variety of different autoimmune diseases but ...
Since this activity occurs in the nucleus of the cell ATA is a form of antinuclear antibody. Scleroderma results from the overproduction of collagen in affected tissues, one study claims that there is an increased density of Topoisomerase I sites in the collagen genes, and that the antibodies may be altering transcription at these loci.

Immunofluorescence pattern of SS-A and SS-B antibodies. Produced using serum from a patient on HEp-20-10 cells with a FITC conjugate. Anti-SSA autoantibodies (anti–Sjögren's-syndrome-related antigen A autoantibodies, also called anti-Ro, or similar names including anti-SSA/Ro, anti-Ro/SSA, anti–SS-A/Ro, and anti-Ro/SS-A) are a type of anti-nuclear autoantibodies that are associated with ...
Somatostatin receptor antagonists (or somatostatin inhibitors) are a class of chemical compounds that work by imitating the structure of the neuropeptide somatostatin. The somatostatin receptors are G protein-coupled receptors. Somatostatin receptor subtypes in humans are sstr1, 2A, 2 B, 3, 4 and 5. [1]
Antibodies against the body's own products are called autoantibodies. Autoantibodies can sometimes errantly be directed against healthy portions of the organism, causing autoimmune diseases. ATA can be classified according to 2 different schemes: transglutaminase isoform and immunoglobulin reactivity subclass (IgA, IgG) toward transglutaminases.
Somatostatin is encoded by a CRE and is very susceptible to gene promoter region activation by transcription factor CREB. [1] There are five known somatostatin receptors: [2] SST 1 ; SST 2 ; SST 3 ; SST 4 ; SST 5 ; All are G protein-coupled seven transmembrane receptors.
Goldberg test may refer to any of various psychiatric tests used to assess mental health in general or as screening tools for specific mental disorders e.g. depression or bipolar disorder. Goldberg , after whom some psychiatric tests are named, might be one of two psychiatrists who share the same last name: Ivan Goldberg , an American ...
