Figure 1. Detection of HEV in a single infected islet.
A human islet, infected for 72 h (A-C) or 12 h (D-F) was mixed with non-infected cultured pancreatic cells, a pancreatic tissue biopsy, or used alone for RNA extraction. RT-snPCR with primers in the 5’ untranslated region (B, E) or in the VP3-VP1 region (C, F) was used for detection of HEV genome. The products from the first (PCR#1) and seminested (PCR#2) reactions were analyzed on a 1.5% agarose gel containing SYBR® Safe. Immunohistochemical staining with an antibody against HEV VP1 was used for detection of HEV protein (A, D). A representative infected islet, infected for 72 h (A) or 12 h (D) is shown.
