Figure 3

A diagram illustrating mechanisms that control sialylation of PrPSc. (A) The sialylation status of PrPC is controlled by STs in the trans-Golgi. (B) NEUs do not appear to affect the steady-state sialylation level of PrPC, presumably because desialylated PrPC is degraded rapidly. (C) Sialoglycoforms of PrPC are recruitment into PrPSc selectively according to their sialylation status and in a strain-specific manner. (D) In SLOs, PrPSc is a subject of post-conversion sialylation by STs. Sias are shown as red diamonds.
