Interleukin-2 works by:
- Blocking the reproduction and spread of cancer cells
- Stimulating the development of white blood cells that attack cancer
- Causing cancer cells to release chemicals that attract cancer-killing immune system cells
What is Interleukin-2 (IL-2) immunotherapy?
Interleukin-2 (IL-2, Aldesleukin, PROLEUKIN®) Immunotherapy is cancer treatment that stimulates the body’s immune system to fight cancer, such as melanoma. Interleukin-2 is systemic therapy, which means that the treatment reaches all parts of your body through the bloodstream.
How does IL-2 work in melanoma?
IL-2 works as a systemic treatment to: As an immunotherapy, IL-2 stimulates your immune system, which has an immunological “memory.” That means that IL-2 may help your immune system continue to attack melanoma cells even after your treatment ends.
What is IL-2 used for?
What IL-2 Is Used For: Cancers treated with IL-2 include renal cell (kidney) and melanoma, a skin cancer. Note: If a drug has been approved for one use, physicians sometimes elect to use this same drug for other problems if they believe it may be helpful. How IL-2 Is Given:
How long does it take for IL-2 to work?
While a person with cancer would take IL-2 therapy for about a week, autoimmune diseases are chronic, and IL-2 might have to be given over long periods. IL-2 could activate other immune cells, which could counteract the autoimmune effort.
How does interleukin treatment work?
It: works directly on cancer cells by interfering with how the cells grow and multiply. stimulates the immune system by encouraging the growth of killer T cells and other cells that attack cancer cells. encourages cancer cells to send out chemicals that attract immune system cells.
What is the mechanism of action of interleukin-2?
Abstract. The T cell lymphokine, interleukin-2 (IL-2), plays a pivotal role in an immune response by stimulating antigen-activated B lymphocytes to progress through the cell cycle and to differentiate into antibody-secreting cells.
What does interleukin-2 stimulate?
Interleukin-2 (IL-2) is one of a family of polypeptides that mediate interactions between leukocytes. It was initially called T-cell growth factor. It stimulates proliferation and enhances function of other T-cells, natural killer (NK) cells and B-cells.

What is an IL-2 inhibitor?
IL-2 is primarily involved in the regulation of T-lymphocytes proliferation but also activates natural killer (NK), B- and lymphokine-activated killer (LAK) cells. Inappropriate responses of T-lymphocytes are associated with a range of immune diseases, including allergies and autoimmune diseases.
Which interleukin suppresses the activity of IL-2?
Interleukin-10Interleukin-10, originally identified as an inhibitor of interferon gamma (IFN-γ) and IL-2 synthesis in Th2 cells (26), efficiently inhibits proliferative and cytokine responses in T cells (1) and was shown to mediate both immunological unresponsiveness and the suppression of immune reactions (27).

The interleukin (IL)-2 receptor (IL-2R) α-chain (CD25) is being shed upon immune activation. Increased levels of soluble (s)IL-2R, therefore, are considered as an indication of an on-going immune response which could be used to monitor immune-mediated diseases.
What is IL-2 and its role in T-cell activation after an encounter with the target antigen?
IL-2 plays a dual role in T cell activation by stimulating the proliferation and differentiation of 'conventional' T cells as well as maintaining and expanding the population of 'suppressive' Treg cells (Fig.

What is IL-2 in medicine?
Interleukin-2 (IL-2) is a potent human protein that can activate and also dampen the body’s immune response . Nearly 30 years after the US Food and Drug Administration first approved IL-2 to treat melanoma and kidney cancer, a host of pharma and biotech companies are racing to the clinic with engineered versions of the protein that they hope will be safer and more precise than those in use today. Others are trying to harness IL-2’s immune-suppressive power to treat autoimmune diseases.
What are the problems with IL-2?
All are trying to solve therapeutic IL-2’s fundamental problems—a short half-life that requires toxic dosing levels, nonspecific binding that stalls efficacy and causes side effects, and a tendency to spur the production of antibodies that could affect the efficacy of the drug or native IL-2.
What is the drug that stimulates the immune system?
But there was a drug called Proleukin that, for better or worse, gripped his attention. Proleukin, also called aldesleukin, was a therapeutic version of interleukin-2 (IL-2), a small human protein called a cytokine that could attach to specific kinds of immune cells and stimulate them to grow and divide.
