Abstract
Th17 cells have been shown to play an important role in the pathogenesis of a variety of autoimmune diseases. The aim of this study was to investigate the potential role of Th17 cells in autoimmune pancreatitis (AIP). Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to determine gene expression of the signature cytokines of Th17 cells IL-17A and IL-21 and of the Th17 lineage-specific transcription factor retinoic acid receptor-related orphan receptor C (RORC) in human tissue specimens of AIP, classical chronic pancreatitis (CP), and normal pancreas (NP). Infiltrating immune cells were characterized by immunohistochemistry (IHC). Gene expression of IL-17A, IL-21, and RORC were found to be significantly increased in AIP. Accordingly, the number of Th17 cells was significantly increased in AIP compared to NP or CP. Both gene expression analysis and IHC revealed a clear difference between type 1 and 2 AIP. In the periductal compartment of type 2 AIP, which is characterized by granulocytic epithelial lesions (GELs), the number of infiltrating Th17 cells and neutrophilic granulocytes was significantly increased compared to type 1 AIP. Our data suggest that Th17 cells play a role in the pathogenesis of AIP, in particular of type 2 AIP. Cross-talk between Th17 cells and neutrophilic granulocytes mediated via IL-17A may be a potential mechanism by which neutrophils are recruited to the duct and acinar cells with subsequent destruction, a process that is pathognomonic for type 2 AIP.

Abstract
Intraductal papillary mucinous neoplasms (IPMN) are precursor lesions of ductal adenocarcinoma of the pancreas and one of the most common cystic entities in this organ. Branch and main duct types are further distinguished based on the tumor localization. An additional classification is based on the predominant architecture and immunohistochemical profile with four prognostic relevant subtypes, gastric, intestinal, pancreato-biliary and oncocytic. This review provides an overview about the malignant potential of the different subtypes and the prognosis of associated invasive tumors and gives recommendations for the pathological assessment of resection specimens with IPMNs.

Abstract
OBJECTIVES Mutations in the Parkin gene can cause autosomal recessive early-onset Parkinson's disease (PD). Recently, Parkin mutations were also suggested to play a role in the commoner late-onset forms of PD. METHODS We compared a German cohort of PD patients (95) with a Norwegian cohort of PD patients (96). Both cohorts have predominant late-onset form of PD. Mutation and polymorphism frequencies were compared via single-strand conformation polymorphism and sequence analyses. RESULTS Three heterozygous missense mutations (Arg256Cys, Arg402Cys and Thr240Met) were found in late-onset PD patients in the German patient cohort (1.6%). A missense mutation (Arg402Cys) was also found in one of 149 healthy control subjects (0.3%). Only one heterozygous missense mutation (Arg256Cys) was identified in a Norwegian patient suffering from late-onset PD (0.5%). The frequencies of four known single nucleotide polymorphisms significantly differ between the two distant European populations. CONCLUSION The results support the hypothesis that heterozygous mutations in the Parkin gene may act as susceptibility alleles for late-onset forms of PD in rare cases.
