General description

Interleukin-10 (IL-10) is an immunosuppressive cytokine produced by a variety of mammalian cell types including macrophages, monocytes, T cells, B cells and keratinocytes. Human IL-10 active on murine cells, but murine IL-10 is inactive on human cells. The gene encoding this protein is localized on human chromosome 1q31-32. Recombinant human IL-10 is an 18.6 kDa protein of 161 amino acid residues. Interleukin 10 (IL-10) comprises interferon IFN-γ fold and exists as a symmetric homodimer. It shares structural similarity with interferon γ (IFN-γ).

Application

Interleukin 10 (IL-10) human has been used in enzyme-linked immunosorbent assay.

Biochem/physiol Actions

Interleukin-10 (IL-10) is an anti-inflammatory protein that inhibits the expression of proinflammatory cytokines such as IL-1 and tumor necrosis factor-α (TNF-α). Like IL-4, IL-10 enhances humoral immune responses and attenuates cell-mediated immune reactions. It inhibits the production of IFN-γ and antigen-specific proliferation of type-1 T helper cells (Th1). It protects the host tissue from damage during immune responses. The protein has a role in modulating viral immunity. IL-10 enhances cytokine production, natural killer cell proliferation and cytotoxicity in vitro. IL-10 is an immunosuppressive cytokine. It promotes wound repair and functions to resolve inflammation in the central nervous system. IL-10 mediates its signaling function through the interleukin receptors namely, IL-10RA and two IL-10RBs. The expression of IL-10 is regulated by signal transducer and activator of transcription 3 (STAT3) and suppressor of cytokine signaling-3 (SOCS3) ratios. Polymorphisms in the IL-10 gene is implicated in breast cancer.

Physical form

Lyophilized from 20 mM Sodium Phosphate, pH 7.2.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.

Resident cells of the central nervous system (CNS) play an important role in detecting insults and initiating protective or sometimes detrimental host immunity. At peripheral sites, immune responses follow a biphasic course with the rapid, but transient, production of inflammatory...

Interleukin 10 (IL-10) is a dimeric cytokine that plays a central role in suppressing inflammatory responses. These activities are dependent on the interaction of IL-10 with its high-affinity receptor (IL-10R1). This intermediate complex must subsequently recruit the low-affinity IL-10R2 chain...

Interleukin (IL)-10, a multifunctional immune-regulatory cytokine with both immunosuppressive and anti-angiogenic functions, is produced by immune cells including macrophages, T lymphocytes, and natural killer cells. Among other effects, IL-10 promotes tumor cell proliferation and metastasis via immunosuppression. Interleukin-10-mediated immunosuppression is...
