IL6soluble

IL6soluble, also known as soluble interleukin-6 (sIL-6), is a form of the interleukin-6 (IL-6) protein that is not bound to its membrane receptor. IL-6 is a cytokine, a type of protein that plays a crucial role in the immune system and inflammation. It is produced by various cells, including immune cells, fibroblasts, and endothelial cells, in response to infection, injury, or other stimuli.

IL6soluble is a truncated form of IL-6 that lacks the membrane-binding domain, allowing it to circulate freely in the bloodstream. This soluble form can bind to the soluble IL-6 receptor (sIL-6R), forming a complex that can be measured in biological samples. The concentration of sIL-6 in the blood is often used as a biomarker for inflammation and disease activity in conditions such as rheumatoid arthritis, systemic lupus erythematosus, and inflammatory bowel disease.

The measurement of sIL-6 levels can provide valuable information about the body's inflammatory response and the effectiveness of treatment. However, it is important to note that sIL-6 levels can be influenced by various factors, including age, sex, and underlying medical conditions. Therefore, interpretation of sIL-6 levels should be done in the context of the individual patient's clinical presentation and other relevant laboratory findings.
