How does interleukin 1 amplify the body respond to an invasion?

Interleukin-1 (IL-1) is a key pro-inflammatory cytokine that plays a crucial role in amplifying the immune response to infections and tissue damage. It is produced by activated macrophages and other immune cells in response to pathogens or injury. IL-1 enhances the recruitment and activation of additional immune cells, such as neutrophils and T cells, while also promoting the production of other inflammatory mediators. This amplification helps to increase the overall inflammatory response, facilitating a more effective defense against invading pathogens.
