Cholinergic Urticaria
Cholinergic urticaria (CU) presents with tiny very itchy wheals and small bumps on a reddish background. It is a type of physical urticaria (or ''hives'') that appears when a person is sweating or their core body temperature increases. Symptoms Cholinergic urticaria typically presents with a number of small, short-lasting hives but may also involve cutaneous inflammation (wheals) and pain which develops usually in response to exercise, bathing, staying in a heated environment, or emotional stress. Although the symptoms subside rapidly, commonly within 1 hour, cholinergic urticaria may significantly impair quality of life, especially in relation to sporting activities. Causes * Sweat hypersensitivity * Acquired anhidrosis and/or hypohidrosis * Idiopathic * Opioid use * Cholinesterase inhibitors Subtypes Sweat hypersensitivity This subtype of CU refers to those who are hypersensitive to their own sweat. Diagnosis Diagnosis is made by injecting autologous (the person's own) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheals
A skin condition, also known as cutaneous condition, is any medical condition that affects the integumentary system—the organ system that encloses the body and includes skin, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. Conditions of the human integumentary system constitute a broad spectrum of diseases, also known as dermatoses, as well as many nonpathologic states (like, in certain circumstances, melanonychia and racquet nails). While only a small number of skin diseases account for most visits to the physician, thousands of skin conditions have been described. Classification of these conditions often presents many nosological challenges, since underlying causes and pathogenetics are often not known. Therefore, most current textbooks present a classification based on location (for example, conditions of the mucous membrane), morphology ( chronic blistering conditions), cause (skin conditions resul ...

Propranolol
Propranolol, sold under the brand name Inderal among others, is a medication of the beta blocker class. It is used to treat high blood pressure, a number of types of irregular heart rate, thyrotoxicosis, capillary hemangiomas, performance anxiety, and essential tremors, as well to prevent migraine headaches, and to prevent further heart problems in those with angina or previous heart attacks. It can be taken by mouth or by injection into a vein. The formulation that is taken by mouth comes in short-acting and long-acting versions. Propranolol appears in the blood after 30 minutes and has a maximum effect between 60 and 90 minutes when taken by mouth. Common side effects include nausea, abdominal pain, and constipation. It should not be used in those with an already slow heart rate and most of those with heart failure. Quickly stopping the medication in those with coronary artery disease may worsen symptoms. It may worsen the symptoms of asthma. Caution is recommended in those ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CD8+
A cytotoxic T cell (also known as TC, cytotoxic T lymphocyte, CTL, T-killer cell, cytolytic T cell, CD8+ T-cell or killer T cell) is a T lymphocyte (a type of white blood cell) that kills cancer cells, cells that are infected by intracellular pathogens (such as viruses or bacteria), or cells that are damaged in other ways. Most cytotoxic T cells express T-cell receptors (TCRs) that can recognize a specific antigen. An antigen is a molecule capable of stimulating an immune response and is often produced by cancer cells, viruses, bacteria or intracellular signals. Antigens inside a cell are bound to class I MHC molecules, and brought to the surface of the cell by the class I MHC molecule, where they can be recognized by the T cell. If the TCR is specific for that antigen, it binds to the complex of the class I MHC molecule and the antigen, and the T cell destroys the cell. In order for the TCR to bind to the class I MHC molecule, the former must be accompanied by a glycoprotein c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CD4+
In molecular biology, CD4 (cluster of differentiation 4) is a glycoprotein that serves as a co-receptor for the T-cell receptor (TCR). CD4 is found on the surface of immune cells such as T helper cells, monocytes, macrophages, and dendritic cells. It was discovered in the late 1970s and was originally known as leu-3 and T4 (after the OKT4 Monoclonal antibodies, monoclonal antibody that reacted with it) before being named CD4 in 1984. In humans, the CD4 protein is encoded by the ''CD4'' gene. T helper cell, CD4+ T helper cells are leukocytes, white blood cells that are an essential part of the human immune system. They are often referred to as CD4 cells, T-helper cells or T4 cells. They are called helper cells because one of their main roles is to send signals to other types of immune cells, including CD8 cytotoxic t cell, killer cells, which then destroy the infectious particle. If CD4 cells become depleted, for example in untreated HIV infection, or following immune suppressio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CCL17
CCL17 is a powerful chemokine produced in the thymus and by antigen-presenting cells like dendritic cells, macrophages, and monocytes. CCL17 plays a complex role in cancer. It attracts Regulatory T cell, T-regulatory cells allowing for some cancers to evade an immune response. However, in other cancers, such as melanoma, an increase in CCL17 is linked to an improved outcome. CCL17 has also been linked to Autoimmune disease, autoimmune and Allergy, allergic diseases. Classification CCL17 (CC chemokine ligand 17) was initially named TARC (thymus- and activation-regulated chemokine) when first isolated in 1996. It was later renamed CCL17 as the naming conventions for all cytokines were updated to standardize names. Function Cytokines, like CCL17, help cells communicate with one another, and stimulate cell movement. Chemokines are a type of cytokine that attract white blood cells to sites of inflammation or disease. CCL17 as well as its partner chemokine CCL22 induce chemotaxis i ...

CCL5
Chemokine (C-C motif) ligand 5 (also CCL5) is a protein which in humans is encoded by the ''CCL5'' gene. The gene has been discovered in 1990 by ''in situ'' hybridisation and it is localised on 17q11.2-q12 chromosome. It is also known as RANTES (regulated on activation, normal T cell expressed and secreted). RANTES was first described by Dr. Tom Schall who named the protein, the original source of the name Rantes was from the Argentine movie ''Man Facing Southeast'' about an alien who shows up in a mental ward who was named Rantés, the rather clunky acronym was only made to fit the name. Function CCL5 belongs to the CC subfamily of chemokines, due to its adjacent cysteines near N terminus. It is an 8kDa protein acting as a classical chemotactic cytokine or chemokine. It consists of 68 amino acids. CCL5 is proinflammatory chemokine, recruiting leukocytes to the site of inflammation. It is chemotactic for T cells, eosinophils, and basophils, but also for monocytes, natural-ki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CCL2
''For the ICAO airport code see Candle Lake Airpark, for the diradical compound see Dichlorocarbene.'' The chemokine (C-C motif) ligand 2 (CCL2) is also referred to as monocyte chemoattractant protein 1 (MCP1) and small inducible cytokine A2. CCL2 is a small cytokine that belongs to the CC chemokine family. CCL2 tightly regulates cellular mechanics and thereby recruits monocytes, memory T cells, and dendritic cells to the sites of inflammation produced by either tissue injury or infection. Genomics In the human genome, CCL2 and many other CC chemokines are located on chromosome 17 (17q11.2-q21.1). The gene span is 1,927 bases and the CCL2 gene resides on the Watson (plus) strand. The CCL2 gene has three exons and two introns. The CCL2 protein precursor contains a signal peptide of 23 amino acids. In turn, the mature CCL2 is 76 amino acids long. The CCL2 predicted weight is 11.025 kiloDaltons (kDa). Population genetics In humans, the levels of CCL2 can vary considerably. In the ...

CHRM3
The muscarinic acetylcholine receptor, also known as cholinergic/acetylcholine receptor M3, or the muscarinic 3, is a muscarinic acetylcholine receptor encoded by the human gene CHRM3. The M3 muscarinic receptors are located at many places in the body, e.g., smooth muscles, the endocrine glands, the exocrine glands, lungs, pancreas and the brain. In the CNS, they induce emesis. Muscarinic M3 receptors are expressed in regions of the brain that regulate insulin homeostasis, such as the hypothalamus and dorsal vagal complex of the brainstem. These receptors are highly expressed on pancreatic beta cells and are critical regulators of glucose homoestasis by modulating insulin secretion. In general, they cause smooth muscle contraction and increased glandular secretions. They are unresponsive to PTX and CTX. Mechanism Like the M1 muscarinic receptor, M3 receptors are coupled to G proteins of class Gq, which upregulate phospholipase C and, therefore, inositol trisphosphate and i ...
