WebThe major treatment for cystinosis is a cystine-depleting medication called cysteamine. Cysteamine is taken up by cells and binds to cystine within the lysosome, allowing it to escape the lysosome through a different transporter protein. This prevents cystine accumulation and crystal formation. WebCysteamine, is an aminothiol that enters the lysosome to combine with cystine, forming a cysteamine-cystine disulfide molecule that can exit the lysosome via an alternative lysosomal protein PQLC2.
