Description

General description

Interleukin 7, also known as IL7, IL-7, and is a hematopoietic growth factor secreted by stromal cells in the red marrow and thymus. It is also produced by keratinocytes, dendritic cells, hepatocytes, neurons, and epithelial cells but is not produced by lymphocytes. IL-7 stimulates the differentiation of multipotent (pluripotent) hematopoietic stem cells into lymphoid progenitor cells. It also stimulates proliferation of all cells in the lymphoid lineage (B cells, T cells and NK cells). It is important for proliferation during certain stages of B-cell maturation, T and NK cell survival, development and homeostasis. IL-7 is a cytokine important for B and T cell development. This cytokine and the hepatocyte growth factor (HGF) form a heterodimer that functions as a pre-pro-B cell growth-stimulating factor. IL-7 binds to the IL-7 receptor, a heterodimer consisting of Interleukin-7 receptor α and common gamma chain receptor. Il-7 promotes hematological malignacies (acute lymphoblastic leukemia, T cell lymphoma). Elevated levels of IL-7 have also been detected in the plasma of HIV-infected patients. IL-7 as an immunotherapy agent has been examined in many pre-clinical animal studies and more recently in human clinical trials for various malignancies and during HIV infection. IL-7 could also be beneficial in improving immune recovery after allogenic stem cell transplant.

Interleukin-7 (IL-7) is a cytokine. It is synthesized by stromal cells, epithelial cells, endothelial and immune cells. The IL-7 gene is located on human chromosome 8q21.

Biochem/physiol Actions

Interleukin-7 (IL-7) plays a major role in innate and adaptive immunity. It participates in B and T cell development and osteoblasts differentiation of multiple myeloma. IL-7 is also involved in the development, survival and proliferation of lymphocytes. It has the ability to prevent the initiation of MAPK signaling.

Physical form

Lyophilized from 0.22 μm filtered solution in in PBS, pH 7.4. Generally 5-8% Mannitol or trehalose is added as a protectant before lyophilization.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in sterile deionized water to a concentration of 50 μg/mL. Do not vortex. This solution can be stored at 2-8°C for up to 1 month. For extended storage, it is recommended to store at -20°C.
