What is the primary function of IL-1 in inflammatory processes?

The primary function of interleukin-1 (IL-1) in inflammatory processes is to induce fever and activate T-cells. IL-1 is a key pro-inflammatory cytokine that plays a crucial role in the body's immune response. When released by activated macrophages and other immune cells, IL-1 acts on the hypothalamus to raise body temperature, leading to fever, which is a common systemic response to infection and inflammation. This fever can help inhibit the growth of pathogens and enhance the function of the immune system.

Moreover, IL-1 is vital for the activation and proliferation of T-cells, which are critical players in the adaptive immune response. By stimulating T-cell activation, IL-1 helps in orchestrating the immune response against pathogens, thus playing a significant role in both the innate and adaptive aspects of inflammation.

While other options mention important biological processes, they do not directly relate to the primary function of IL-1 in the context of inflammatory processes. Antibody production, erythropoiesis, and blood pressure regulation are influenced by other cytokines and factors within the immune and circulatory systems, but they do not reflect IL-1's main role in promoting fever and T-cell activation during inflammation.
