Ammonium chloride, an inhibitor of phagosome-lysosome fusion in macrophages, concurrently induces phagosome-endosome fusion, and opens a novel pathway: studies of a pathogenic mycobacterium and a nonpathogenic yeast

The weak base ammonium chloride has been previously reported to inhibit lysosomal movements and phagosome-lysosome (Ph-L) fusion in cultured mouse macrophages (M phi), thus reducing delivery, to an intraphagosomal infection, of endocytosed solutes that have concentrated in secondary lysosomes. We ha...
