naturally occurring protein that inhibits inflammatory molecule interleukin-1
Interleukin-1 Receptor Antagonist (IL-1RA) is a naturally occurring protein that inhibits the activity of interleukin-1 (IL-1), a molecule involved in inflammatory responses. By blocking IL-1 from binding to its receptor, IL-1RA helps reduce inflammation and is used in treatments for conditions like rheumatoid arthritis and other inflammatory diseases.
