26. Immunostained cells expressing PrP(c) appear scattered throughout the epithelium of fundic and pyloric glands as well as in intestinal villi and crypts. PMID: 15891070
27. These results indicate that DRMs are essential for proper trafficking and distribution of PrP(C) at late stages of neuronal differentiation and that its function, at least in hippocampus, is restricted to the axonal domain. PMID: 16139509
