Cargo-mediated cellular pathway

Cargo-mediated cellular pathways refer to the biological processes involved in the sorted transport of proteins, lipids, and other macromolecules via membrane-bound vesicles (Nature Reviews Molecular Cell Biology, 2017). These pathways include endocytosis, exocytosis, and the movement of vesicles between intracellular compartments such as the endoplasmic reticulum and the Golgi apparatus (Molecular Biology of the Cell, 6th ed.). These processes are vital for maintaining cellular homeostasis, allowing cells to respond to external signals and maintain organelle identity. Dysregulation of these transport mechanisms is implicated in various pathologies, including neurodegenerative diseases where protein trafficking fails and cancer where receptor signaling is prolonged (Journal of Cell Science, 2018). Additionally, many viruses and toxins exploit these pathways to gain entry into host cells (Nature Reviews Microbiology, 2014). However, the term "cargo-mediated cellular pathways" describes a broad physiological system rather than a discrete molecular target like a specific receptor or enzyme. In drug discovery, therapeutic intervention typically focuses on specific molecular components within these pathways, such as clathrin, dynamin, or various Rab GTPases (Pharmacological Reviews, 2016). Because this entry lacks a specific molecular identity and represents a broad category of functions, it is not considered a valid canonical therapeutic target.
