Summary of the comparative study of pancreata from T1D and non-diabetic control patients. Sections were first stained for viral RNA, with a combination RNA probe sets CVB_1, CVB_2 and CVB_3, followed by insulin staining. - = less than 10 fully-infected cells, + = 10 to 30 fully-infected cells, ++ = 30 to 100 fully-infected cells, +++ = 100 to 200 fully-infected cells, ++++ = more than 200 fully-infected cells in the exocrine. §E554A showed ten fully-infected cells, E235 contained just 5 islets on the section and 8869 just 2 full and 1 fragmented islets (very small sections).
