New approaches to the control of chronic inflammatory diseases with a focus on the endolysosomal system of immune cells.
Chronic inflammation is implicated in many types of diseases, including cardiovascular, neurodegenerative, metabolic, and immune disorders. The search for therapeutic targets to control chronic inflammation often involves narrowing down the various molecules associated with pathology that have been discovered by various omics analyses. Herein, a different approach to identify therapeutic targets against chronic inflammation is proposed and one such target is discussed as an example. In chronically inflamed tissues, a large number of cells receive diverse proinflammatory signals, the intracellular signals are intricately integrated, and complicated intercellular interactions are orchestrated. This review focuses on effectively blocking this chaotic inflammatory signaling network via the endolysosomal system, which acts as a cellular signaling hub. In endolysosomes, the inflammatory signals mediated by pathogen sensors, such as Toll-like receptors, and the signals from nutrient and metabolic pathways are integrally regulated. Disruption of endolysosome signaling results in a strong anti-inflammatory effect by disrupting various signaling pathways, including pathogen sensor-mediated signals, in multiple immune cells. The endolysosome-resident amino acid transporter, solute carrier family 15 member 4 (SLC15A4), which plays an important role in the regulation of endolysosome-mediated signals, is a promising therapeutic target for several inflammatory diseases, including autoimmune diseases. The mechanisms by which SLC15A4 regulates inflammatory responses may provide a proof of concept for the efficacy of therapeutic strategies targeting immune cell endolysosomes.
