Multiple cellular and systemic pathways

The term Multiple cellular and systemic pathways does not refer to a single molecular target, such as a specific protein or receptor, but rather describes a broad range of biological processes and signaling networks affected by a therapeutic agent. This designation is frequently used in pharmacology to describe drugs with pleiotropic effects, where the clinical outcome is the result of interacting with various receptors, enzymes, and metabolic cycles across different tissues (PMID: 30830285). For example, systemic therapies like glucocorticoids or certain metabolic regulators influence inflammation, glucose metabolism, and immune responses simultaneously rather than acting on a solitary pathway (PMID: 28636115). Because it lacks a specific biochemical identity or UniProt entry, it is considered a functional or categorical description rather than a discrete therapeutic target. In drug development, agents that impact multiple pathways require a systems biology approach to evaluate the net effect on organismal health and to monitor for widespread physiological side effects.
