interleukin-1 alpha (IL-1α)

Interleukin-1 alpha (IL-1α) is a protein that plays a key role in the body's immune response. It acts as a signaling molecule, or cytokine, helping the immune system recognize and respond to infections or injuries by promoting inflammation. IL-1α is produced by various cells, especially when there’s tissue damage, and it triggers other immune activities, such as attracting white blood cells to the affected area. This process is crucial for fighting infections and healing wounds, but excessive IL-1α activity can also contribute to inflammatory diseases.
