IL2RA
Interleukin-2 receptor alpha chain (also called CD25) is the human protein encoded by the ''IL2RA'' gene. The interleukin 2 (IL2) receptor alpha (IL2RA) and beta (IL2RB) chains, together with the common gamma chain (IL2RG), constitute the high-affinity IL2 receptor. Homodimeric alpha chains (IL2RA) result in low-affinity receptor, while homodimeric beta (IL2RB) chains produce a medium-affinity receptor. Normally an integral-membrane protein, soluble IL2RA has been isolated and determined to result from extracellular proteolysis. Alternately-spliced IL2RA mRNAs have been isolated, but the significance of each is currently unknown. Description It is a type I transmembrane protein present on activated T cells, activated B cells, some thymocytes, myeloid precursors, and oligodendrocytes. Though IL2RA has been used as a marker to identify CD4+FoxP3+ regulatory T cells in mice, it has been found that a large proportion of resting memory T cells constitutively express IL2RA in humans. ...

Interleukin 15
Interleukin-15 (IL-15) is a cytokine with structural similarity to Interleukin-2 (IL-2). Like IL-2, IL-15 binds to and signals through a complex composed of IL-2/IL-15 receptor beta chain (CD122) and the common gamma chain (gamma-C, CD132). IL-15 is secreted by mononuclear phagocytes (and some other cells) following infection by virus(es). This cytokine induces the proliferation of natural killer cells, i.e. cells of the innate immune system whose principal role is to kill virally infected cells. Expression IL-15 was discovered in 1994 by two different laboratories, and characterized as T cell growth factor. Together with Interleukin-2 (IL-2), Interleukin-4 ( IL-4), Interleukin-7 ( IL-7), Interleukin-9 ( IL-9), granulocyte colony-stimulating factor (G-CSF), and granulocyte-macrophage colony-stimulating factor (GM-CSF), IL-15 belongs to the four α-helix bundle family of cytokines. IL-15 is constitutively expressed by a large number of cell types and tissues, including mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adult T-cell Leukemia/lymphoma
Adult T-cell leukemia/lymphoma (ATL or ATLL) is a rare cancer of the immune system's T-cells caused by human T cell leukemia/lymphotropic virus type 1 (HTLV-1). All ATL cells contain integrated HTLV-1 provirus further supporting that causal role of the virus in the cause of the neoplasm. A small amount of HTLV-1 individuals progress to develop ATL with a long latency period between infection and ATL development. Â ATL is categorized into 4 subtypes: acute, smoldering, lymphoma-type, chronic. Acute and Lymphoma-type are known to particularity be aggressive with poorer prognosis. Globally, the retrovirus HTLV-1 is estimated to infect 20 million people with the incidence of ATL approximately 0.05 per 100,000 with endemic regions such as regions of Japan, as high as 27 per 100,000. However, cases have increased in non-endemic regions with highest incidence of HTLV-1 in southern/northern islands of Japan, Caribbean, Central and South America, intertropical Africa, Romania, northern Iran ...

Lymphokine
Lymphokines are a subset of cytokines that are produced by a type of immune cell known as a lymphocyte. They are protein mediators typically produced by T cells to direct the immune system response by signaling between its cells. Lymphokines have many roles, including the attraction of other immune cells, including macrophages and other lymphocytes, to an infected site and their subsequent activation to prepare them to mount an immune response. Circulating lymphocytes can detect a very small concentration of lymphokine and then move up the concentration gradient towards where the immune response is required. Lymphokines aid B cells to produce antibodies. Important lymphokines secreted by the T helper cell include:Guyton, AC; Hall, JE. (2006) Medical Physiology, Elsevier Saunders. 11th edition, pp.447. * Interleukin 2 * Interleukin 3 * Interleukin 4 * Interleukin 5 * Interleukin 6 * Granulocyte-macrophage colony-stimulating factor * Interferon-gamma Interferon gamma (IFN-γ) is ...

Interleukin-2
Interleukin-2 (IL-2) is an interleukin, a type of cytokine signaling molecule in the immune system. It is a 15.5–16 kDa protein that regulates the activities of white blood cells (leukocytes, often lymphocytes) that are responsible for immunity. IL-2 is part of the body's natural response to microbial infection, and in discriminating between foreign ("non-self") and "self". IL-2 mediates its effects by binding to IL-2 receptors, which are expressed by lymphocytes. The major sources of IL-2 are activated CD4+ T cells and activated CD8+ T cells. IL-2 receptor IL-2 is a member of a cytokine family, each member of which has a four alpha helix bundle; the family also includes IL-4, IL-7, IL-9, IL-15 and IL-21. IL-2 signals through the IL-2 receptor, a complex consisting of three chains, termed alpha (CD25), beta (CD122) and gamma ( CD132). The gamma chain is shared by all family members. The IL-2 receptor (IL-2R) α subunit binds IL-2 with low affinity (Kd~ 10â ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daclizumab
Daclizumab (trade name Zinbryta) is a therapeutic humanized monoclonal antibody which was used for the treatment of adults with relapsing forms of multiple sclerosis (MS). Daclizumab works by binding to CD25, the alpha subunit of the IL-2 receptor of T-cells. In March 2018, it was voluntarily withdrawn from the market by Biogen and Abbvie after reports of autoimmune encephalitis in Europe. Medical uses Daclizumab was used to treat adults with relapsing forms of multiple sclerosis.FDBLA Approval letterMay 27, 2016 It is administered subcutaneously. In clinical trials, decreases of 45% in annualized relapse rate have been reported, as well as a 41% reduction in the proportion of patients who relapsed, and a 54% reduction in the number of new lesions. A 2013 Cochrane systematic review concluded that there was insufficient evidence to determine the efficacy of daclizumab relative to placebo in people with relapsing-remitting MS and, prior to its being discontinued, the need to inves ...

Waldmann Disease
Waldmann disease is a rare disease characterized by enlargement of the lymph vessels supplying the lamina propria of the small intestine. Although its prevalence is unknown, it being classified as a "rare disease" means that less than 200,000 of the population of the United States are affected by this condition and its subtypes. Signs and symptoms Signs and symptoms of the disease include diarrhea, nausea, Swelling (medical), swelling of the legs, protein-losing enteropathy, immunodeficiency and loss of lymphatic fluid into the intestines. It is usually diagnosed before the patient is 3 years old, but it is sometimes diagnosed in adults. Pathophysiology The illness is usually caused by lymphatic vessels that were misshaped at birth, causing obstruction and subsequent enlargement. The condition can also be a result of other illnesses such as constrictive pericarditis and pancreatitis. Diagnosis The disease is diagnosed by doing a biopsy of the affected area. Severity of the dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1930 Births
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 '' Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
