Study Overview
We are able to evaluate the anti-inflammatory effects of test substance on various cell types.
Inflammatory cells such as the J774.1 mouse-derived macrophage line, produce cytokines such as TNF-α and IL-6 in response to Lipopolysaccharide (LPS), a common substance that induces inflammation. TNF-α and IL-6 can be beneficial, by promoting the differentiation of osteoclast precursor cells into osteoclasts, but excessive production of these cytokines induces bone resorption (bone breakdown) by osteoclasts, leading to osteoporosis and rheumatoid arthritis. Additionally, TNF-α has been suggested to accelerate cellular dysfunction in hepatocytes, leading to liver cirrhosis and liver failure. As such, understanding which substances are able to suppress TNF-α and IL-6 are gaining interest for potential therapies. Below, we introduce an assay using J774.1 cells as an example to understand the anti-inflammatory effects of a test substance.-α production.
