Systemic tissue-level processes

Systemic tissue-level processes refer to the integrated physiological activities that occur across multiple tissues and organ systems to maintain organismal homeostasis (Guyton and Hall Textbook of Medical Physiology). These processes encompass a wide range of complex biological functions, including the systemic inflammatory response, endocrine signaling, and the regulation of metabolic flux and hemodynamics (NIH - National Institute of General Medical Sciences). Unlike specific molecular targets such as receptors, enzymes, or transporters, systemic processes represent an emergent level of biological complexity resulting from the interaction of numerous cellular and molecular components. In drug discovery and toxicology, these processes are often studied within frameworks like Adverse Outcome Pathways (AOPs) to understand how molecular perturbations lead to organ-level or systemic effects (Nature Reviews Drug Discovery). Because this term describes a broad category of physiological phenomena rather than a discrete, druggable molecule, it is considered an incorrect entry for a specific therapeutic target. Therapeutic agents do not target the process itself but rather modulate specific proteins or pathways that contribute to the overall systemic state.
