  • Western Blot
    0.1 µg/mL
    Recombinant Viral HCMV IL‑10 (Catalog # 117-VL)
  • Neutralization
    Measured by its ability to neutralize IL‑10-mediated inhibition of LPS-induced IL-1 beta secretion in human peripheral blood lymphocytes (PBL). The Neutralization Dose (ND50) is typically 0.15-0.9 μg/mL in the presence of 2 ng/mL Recombinant Viral HCMV IL‑10.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Data Examples
IL-1 beta Secretion Inhibited by IL‑10 and Neutralization by Viral IL‑10 Antibody. Recombinant Viral HCMV IL‑10 (Catalog # 117-VL) inhibits LPS-indecued IL-1 beta secretion in human peripheral blood lymphocytes (PBL) in a dose-dependent manner (orange line). IL-1 beta secretion inhibited by Recombinant Viral HCMV IL‑10 (2 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Viral HCMV IL‑10 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF117). The ND50 is typically 0.15-0.9 μg/mL.

Background: IL-10

Interleukin-10 (IL-10) is a pleiotropic cytokine that plays a crucial role in regulating immune and inflammstory responses (1). It has closely related homologs in the genome of several viruses including the human cytomegalovirus (HCMV), a prevalent pathogen that can remain in humans as a latent infection (2). Viruses use multiple strategies to avoid detection and clearance by the host immune system. One of these strategies is to express virus-encoded host cytokine homologs, such as IL-10, to modulate the host immune system to the virus’ advantage. HCMV IL-10 is encoded from noncontiguous stretches in the viral genome and is transcribed early during infection. It shares 27% amino acid sequence identity with the endogenous human IL-10. Despite its low homology with the human protein, it can bind to the human IL-10 receptor complex and induces signal transduction. HCMV IL-10 has been shown to suppress cytokine production and inhibit proliferation of mitogen-stimulated human peripheral blood mononuclear cells. HCMV IL-10 can also down regulate the antigen-presenting and accessory cell functions of human monocytes. These immunosuppressive properties of HCMV IL-10 likely contribute to immune evasion during virus infection (3).
