What is Interleukin-2?
Mar 14, 2018 · The immune system has many adaptive and dynamic components that are regulated to ensure appropriate, precise and rapid response to a foreign pathogen.

How do antimetabolites work?
Antimetabolites are called a “cytotoxic” type of drug because they kill cells. They work by mimicking the molecules that a cell needs to grow. Cells are tricked into taking in the drugs and then using the antimetabolites instead of their normal building blocks of genetic material: RNA and DNA.May 19, 2020

What is a cytokine response?
COVID-19 infection is accompanied by an aggressive inflammatory response with the release of a large amount of pro-inflammatory cytokines in an event known as “cytokine storm.” The host immune response to the SARS-CoV-2 virus is hyperactive resulting in an excessive inflammatory reaction.Jun 16, 2020
What is the role of IL-2 in the body?
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.
What is the drug called that binds to IL-2?
Eisai markets a drug called denileukin diftitox (trade name Ontak), which is a recombinant fusion protein of the human IL-2 ligand and the diphtheria toxin. This drug binds to IL-2 receptors and introduces the diphtheria toxin into cells that express those receptors, killing the cells. In some leukemias and lymphomas, malignant cells express the IL-2 receptor, so denileukin diftitox can kill them. In 1999 Ontak was approved by the U.S. Food and Drug Administration (FDA) for treatment of cutaneous T cell lymphoma (CTCL).
Why is IL-2 important?
According to an immunology textbook: "IL-2 is particularly important historically, as it is the first type I cytokine that was cloned, the first type I cytokine for which a receptor component was cloned, and was the first short-chain type I cytokine whose receptor structure was solved.
What is the IL-2 protein?
View/Edit Human. View/Edit Mouse. 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.
How does IL-2 affect the immune system?
IL-2 has essential roles in key functions of the immune system, tolerance and immunity, primarily via its direct effects on T cells. In the thymus, where T cells mature, it prevents autoimmune diseases by promoting the differentiation of certain immature T cells into regulatory T cells, which suppress other T cells that are otherwise primed to attack normal healthy cells in the body. IL-2 enhances activation-induced cell death (AICD). IL-2 also promotes the differentiation of T cells into effector T cells and into memory T cells when the initial T cell is also stimulated by an antigen, thus helping the body fight off infections. Together with other polarizing cytokines, IL-2 stimulates naive CD4 + T cell differentiation into Th1 and Th2 lymphocytes while it impedes differentiation into Th17 and folicular Th lymphocytes.
Does IL-2 follow the dose response curve?
IL-2 does not follow the classical dose-respons e curve of chemotherapeutics. The immunological activity of high and low dose IL-2 show sharp contrast. This might be related to different distribution of IL-2 receptors (CD25, CD122, CD132) on different cell populations, resulting in different cells that are activated by high and low dose IL-2. In general high doses are immune suppressive, while low doses can stimulate type 1 immunity. Low-dose IL-2 has been reported to reduce hepatitis C and B infection.
What is the IL-2 receptor?
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.
How does IL-2 affect the immune system?
IL-2 stimulates the immune system and can lead to large increases in the number of CD4+ (T-helper) cells. Unfortunately, these increases in CD4 cells do not produce any improvement in health in people with HIV. IL-2 is usually administered in 5-day cycles of 2 subcutaneous injections a day.
What is IL-2 in the body?
Interleukin-2 (IL-2) is a protein made by the body . T-helper cells, a kind of white blood cell, produce IL-2 when they are stimulated by an infection. IL-2 makes infection-fighting cells multiply and mature. Patients who use IL-2 have large increases in their CD4 cell counts. IL-2 is called an immune modulator.
How often is IL-2 given?
IL-2 is usually administered in 5-day cycles of 2 subcutaneous injections a day. At first, one cycle is given every 8 weeks. IL-2 causes irritation where the injections are given and flu-like symptoms. These side effects usually start within a few hours of IL-2 injections and disappear after the end of a cycle.
