Endosomal Acidification Inhibitor
Chloroquine is a lysosomotropic agent that prevents endosomal acidification [1]. It accumulates inside the acidic parts of the cell, including endosomes and lysosomes.
This accumulation leads to inhibition of lysosomal enzymes that require an acidic pH, and prevents fusion of endosomes and lysosomes.
Chloroquine is commonly used to study the role of endosomal acidification in cellular processes [2, 3], such as the signaling of intracellular TLRs.
Moreover, Chloroquine inhibits autophagy as it raises the lysosomal pH, which leads to inhibition of both fusion of autophagosome with lysosome and lysosomal protein degradation [4].
