Pro-caspase-1 is an inactive precursor of caspase-1, an essential enzyme in the inflammatory response that processes pro-inflammatory cytokines like IL-1β and IL-18 into their active forms. Activation of pro-caspase-1 occurs within the inflammasome complex, a crucial component of the innate immune system's response to pathogens and cellular stress signals.

Pro-inflammatory cytokines are signaling molecules that mediate and regulate the immune response, often leading to inflammation as part of the body's defense mechanism. They play a crucial role in the pathogenesis of various inflammatory and autoimmune diseases by promoting the recruitment and activation of immune cells.

Pro-inflammatory Cytokines

IL-1β is a pro-inflammatory cytokine that plays a critical role in the body's immune response, primarily by mediating inflammation and fever. It is involved in various diseases, including autoimmune disorders and chronic inflammatory conditions, making it a target for therapeutic interventions.

IL-1β

IL-18 is a pro-inflammatory cytokine that plays a crucial role in both innate and adaptive immune responses, often working in synergy with IL-12 to induce IFN-gamma production. It is involved in various inflammatory and autoimmune diseases, making it a target for therapeutic interventions aimed at modulating the immune system.

Cellular stress signals are critical mechanisms that cells use to detect and respond to various stressors, ensuring survival and adaptation. These signals activate specific pathways that can lead to protective responses or, if the stress is severe, trigger programmed cell death to prevent damage to the organism.
