Infectious diseases and cancer are among the key medical challenges that humankind is facing today。 A growing amount of evidence suggests that ion channels in the endolysosomal system play a crucial role in the pathology of both groups of diseases。 The development of advanced patch-clamp technologies has allowed us to directly characterize ion fluxes through endolysosomal ion channels in their native environments。 Endolysosomes are essential organelles for intracellular transport， digestion and metabolism， and maintenance of homeostasis。 The endolysosomal ion channels regulate the function of the endolysosomal system through four basic mechanisms: calcium release， control of membrane potential， pH change， and osmolarity regulation。 In this review， we put particular emphasis on the endolysosomal cation channels， including TPC2 and TRPML2， which are particularly important in monocyte function。 We discuss existing endogenous and synthetic ligands of these channels and summarize current knowledge of their impact on channel activity and function in different cell types。 Moreover， we summarize recent findings on the importance of TPC2 and TRPML2 channels as potential drug targets for the prevention and treatment of the emerging infectious diseases and cancer。
