Multiple Systemic Pathways

Multiple Systemic Pathways is a conceptual term rather than a specific molecular target, receptor, or enzyme. It refers to the integrated network of biological processes—such as inflammation, metabolism, and endocrine signaling—that operate across various organ systems to maintain homeostasis or drive disease progression (Nature Reviews Drug Discovery, 2006). In pharmacology, this term might be used to describe the broad, non-specific effects of systemic therapies like glucocorticoids, which modulate gene expression across nearly all cell types (StatPearls, 2023). It is also frequently used in research to describe the complex pathophysiology of multi-organ diseases like sepsis or systemic lupus erythematosus. Because it does not correspond to a single protein, nucleic acid, or gene product, it cannot be targeted with high precision by a single molecular entity. Consequently, it is classified as an incorrect target name for structured drug-target databases, which require specific biochemical identifiers for therapeutic agents (NIH, 2021). Analysts should instead focus on the specific molecular components, such as cytokines or nuclear receptors, that mediate these systemic effects.
