Lack of Transmission of Chronic Wasting Disease Prions to Human Cerebral Organoids
Figure 4

Figure 4. Western blot analysis of total PrP and PrPres levels in representative organoids for sporadic CJD and CWD-exposed human cerebral organoids in study of lack of transmission of chronic wasting disease prions to 129MM (A) and 129MV (B) human cerebral organoids. Matched KO organoids inoculated with dCWD2 or eCWD are shown for comparison. Densitometric analysis (shown in bottom panels) shows total PrP levels relative to total protein with each point representing an individual organoid; means and SDs are indicated. p values were calculated using Welch’s t-test. Uncropped Western analyses are shown in Appendix Figure 3. CJD, Creutzfeldt-Jakob disease; CWD, chronic wasting disease; dCWD1, whitetail deer CWD; dCWD2, mule deer CWD; dNBH, deer normal brain homogenate; eCWD, elk CWD; eNBH, elk normal brain homogenate; hNBH, human normal brain homogenate; KO, knockout; PrP, prion protein; PrPres, protease-resistant prion protein.
