Abstract
Angiogenesis has been proposed to play a role in the inflammation observed in Sjögren's Syndrome (SS). However, no studies have validated the degree of angiogenesis in salivary glands with SS. Therefore, the goal of this study was to determine the presence and localization of angiogenesis and lymphangiogenesis in salivary glands with SS. We used frozen tissue sections from human minor salivary glands (hMSG) with and without SS in our analyses. To investigate signs of angiogenesis, hMSG tissue lysates were used to detect levels of the pro-angiogenic protein vascular endothelial growth factor (VEGF) by western blot analyses. Additionally, we labeled blood vessels using antibodies specific to platelet endothelial cell adhesion molecule-1 (PECAM-1) and von Willebrand Factor (vWF) to determine blood vessel organization and volume fraction using fluorescence microscopy. Lymphatic vessel organization and volume fraction were determined using antibodies specific to lymphatic vessel endothelial hyaluronan receptor (LYVE-1). Our results suggest that expression levels of VEGF are decreased in hMSG with SS as compared with controls. Interestingly, there were no significant differences in blood or lymphatic vessel organization or volume fraction between hMSG with and without SS, suggesting that angiogenesis and lymphangiogenesis have little impact on the progression of SS.

Abstract
Sjögren's syndrome (SS) is a chronic inflammatory autoimmune disorder that causes secretory dysfunction of the salivary glands leading to dry mouth. Previous studies reported that tight junction (TJ) proteins are down-regulated and lose polarity in human minor salivary glands with SS, suggesting that TJ structure is compromised in SS patients. In this paper, we utilized the NOD/ShiLtJ mouse with the main goal of evaluating this model for future TJ research. We found that the organization of apical proteins in areas proximal and distal to lymphocytic infiltration remained intact in mouse and human salivary glands with SS. These areas looked comparable to control glands (i.e., with no lymphocytic infiltration). TJ staining was absent in areas of lymphocytic infiltration coinciding with the loss of salivary epithelium. Gene expression studies show that most TJs are not significantly altered in 20-week-old NOD/ShiLtJ mice as compared with age-matched C57BL/6 controls. Protein expression studies revealed that the TJ proteins, zonula occludens-1 (ZO-1), occludin, claudin-12, as well as E-cadherin, do not significantly change in NOD/ShiLtJ mice. Our results suggest that ZO-1, occludin and E-cadherin are not altered in areas without lymphocytic infiltration. However, future studies will be necessary to test the functional aspect of these results.

Abstract
The role of a standardized histopathological examination of tissue biopsies and of different tissue compartments (synovia, vascular tissue, bone) is discussed in order to stratify the therapy of different forms of arthritis and other rheumatological diseases. Furthermore the diagnostic steps for the histopathological diagnosis of metabolic osteopathic diseases are highlighted. The synovitis-score is described as a diagnostic device leading to the diagnosis of a low-grade synovitis, which is associated with degenerative and posttraumatic arthropathies, or of a high-grade synovitis which is associated with rheumatic diseases.
