In neuroblastoma cells incubated with MoPrP105-132 for 1 hour at 37°C, MoPrP105-132 was detected in the whole microsomal extract and the cell fraction known to be enriched for Golgi and ER compartments [27], but was not found in either TfR positive or LAMP-1 positive fractions (Figure 2F). Here, LAMP1 is linked to neuroblastoma.
