Giovanni Paisiello was an Italian composer of the Classical era, and was the most popular opera composer of the late 1700s.
Interleukins (ILs) are a group of cytokines that were first seen to be expressed by white blood cells (leukocytes). ILs can be divided into four major groups based on distinguishing structural features. However, their amino acid sequence similarity is rather weak. The human genome encodes more than 50 interleukins and related proteins.
Interleukin 10 (IL-10), also known as human cytokine synthesis inhibitory factor (CSIF), is an anti-inflammatory cytokine. In humans, interleukin 10 is encoded by the IL10 gene. IL-10 signals through a receptor complex consisting of two IL-10 receptor-1 and two IL-10 receptor-2 proteins. Consequently, the functional receptor consists of four IL-10 receptor molecules. IL-10 binding induces STAT3 signalling via the phosphorylation of the cytoplasmic tails of IL-10 receptor 1 + IL-10 receptor 2 by JAK1 and Tyk2 respectively.
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, activated CD8+ T cells, NK cells, dendritic cells and macrophages.
The 1992 United States House of Representatives elections coincided with the 1992 presidential election, in which Democrat Bill Clinton was elected as President, defeating Republican incumbent President George H. W. Bush.
Interleukin 6 (IL-6) is an interleukin that acts as both a pro-inflammatory cytokine and an anti-inflammatory myokine. In humans, it is encoded by the IL6 gene.
The common gamma chain (γc), also known as interleukin-2 receptor subunit gamma or IL-2RG, is a cytokine receptor sub-unit that is common to the receptor complexes for at least six different interleukin receptors: IL-2, IL-4, IL-7, IL-9, IL-15 and interleukin-21 receptor. The γc glycoprotein is a member of the type I cytokine receptor family expressed on most lymphocyte populations, and its gene is found on the X-chromosome of mammals.
Interleukin-22 (IL-22) is protein that in humans is encoded by the IL22 gene.
The interleukin-1 receptor antagonist (IL-1RA) is a protein that in humans is encoded by the IL1RN gene.
Interleukin 6 receptor (IL6R) also known as CD126 is a type I cytokine receptor.
Interleukin 1 receptor, type II (IL-1R2) also known as CD121b is an interleukin receptor. IL1R2 also denotes its human gene.
Interleukin 10 receptor, alpha subunit is a subunit for the interleukin-10 receptor. IL10RA, is its human gene.
Interleukin 1 receptor, type I (IL1R1) also known as CD121a, is an interleukin receptor. IL1R1 also denotes its human gene.
Interleukin-12 receptor, beta 1, or IL-12Rβ1 in short, is a subunit of the interleukin 12 receptor. IL12RB1, is the name of its human gene. IL-12Rβ1 is also known as CD212.
Interleukin 13 receptor, alpha 1, also known as IL13RA1 and CD213A1, is a human gene.
Interleukin 9 receptor (IL9R) also known as CD129 is a type I cytokine receptor. IL9R also denotes its human gene.
Interleukin-36 gamma previously known as interleukin-1 family member 9 (IL1F9) is a protein that in humans is encoded by the IL36G gene.
Interleukin-1 receptor-like 2 is a protein that in humans is encoded by the IL1RL2 gene.
The interleukin-18 receptor 1 (IL-18R1) is an interleukin receptor of the immunoglobulin superfamily. IL18R1 is its human gene. IL18R1 is also known as CDw218a.
Interleukin-23 (IL-23) is a heterodimeric cytokine composed of an IL12B (IL-12p40) subunit and the IL23A (IL-23p19) subunit. A functional receptor for IL-23 has been identified and is composed of IL-12R β1 and IL-23R.
