Interleukin-2 (IL-2) is an interleukin, which is a type of cytokine signaling molecule forming part of the immune system. It is a 15.5–16 kDa protein [ 5 ] that regulates the activities of white blood cells (leukocytes, often lymphocytes ) that are responsible for immunity.
IL-2 binds to the IL-2 receptor, which has three forms, generated by different combinations of three different proteins, often referred to as "chains": α (alpha) (also called IL-2Rα, CD25, or Tac antigen), β (beta) (also called IL-2Rβ, or CD122), and γ (gamma) (also called IL-2Rγ, γ c, common gamma chain, or CD132); these subunits are also parts of receptors for other cytokines.
Interleukin 6 (IL6), also referred to as B-cell stimulatory factor-2 (BSF-2) and interferon beta-2, is a cytokine involved in a wide variety of biological functions. [20] It plays an essential role in the final differentiation of B cells into immunoglobulin-secreting cells, as well as inducing myeloma/plasmacytoma growth, nerve cell ...
Cytokine receptor common subunit gamma also known as interleukin-2 receptor subunit gamma or IL-2RG is a protein that in humans is encoded by the IL2RG gene. [8] The human IL2RG gene is located on the long (q) arm of the X chromosome at position 13.1, from base pair 70,110,279 to base pair 70,114,423.
Interleukin 4 acts on helper T cells to promote the production of T h 2 cytokines (including itself; it is auto-regulatory), while interleukin 10 (IL-10) inhibits a variety of cytokines including interleukin 2 and IFNγ in helper T cells and IL-12 in dendritic cells and macrophages. The combined action of these two cytokines suggests that once ...
The interleukin-2 receptor alpha chain (also called Tac antigen, P55, and mainly CD25) is a protein involved in the assembly of the high-affinity interleukin-2 receptor, consisting of alpha (IL2RA), beta and the common gamma chain ().
The interleukin 2 receptor, which is involved in T cell-mediated immune responses, is present in 3 forms with respect to ability to bind interleukin 2. The low affinity form is a monomer of the alpha subunit (also called CD25) and is not involved in signal transduction. The intermediate affinity form consists of a gamma/beta subunit heterodimer ...
Most BRMs are biopharmaceuticals (biologics), including monoclonal antibodies, interleukin 2, interferons, and various types of colony-stimulating factors (e.g., CSF, GM-CSF, G-CSF). [1] " Immunotherapy makes use of BRMs to enhance the activity of the immune system to increase the body's natural defense mechanisms against cancer", [ 2 ] whereas ...
