Interleukin-17 Impairs Salivary Tight Junction Integrity in Sjögrens Syndrome
Sjögren's syndrome (SS) is an inflammatory autoimmune disease that causes secretory dysfunction of the salivary glands. It has been reported that proinflammatory cytokine interleukin-17 (IL-17) was elevated and tight junction (TJ) integrity disrupted in minor salivary glands from SS patients. However, whether the elevated IL-17 in SS affects TJ integrity and thereby alters the function of salivary gland is unknown. Here, by using nonobese diabetic (NOD) mice as SS model, we found that the stimulated salivary flow rate was significantly decreased in NOD mice. Lymphocyte infiltrati... περισσότερα »
Mast Cells Contribute to Porphyromonas gingivalis-induced Bone Loss
Periodontitis is a chronic inflammatory and bone-destructive disease. Development of periodontitis is associated with dysbiosis of the microbial community, which may be caused by periodontal bacteria, such as *Porphyromonas gingivalis*. Mast cells are sentinels at mucosal surfaces and are a potent source of inflammatory mediators, including tumor necrosis factors (TNF), although their role in the pathogenesis of periodontitis remains to be elucidated. This study sought to determine the contribution of mast cells to local bone destruction following oral infection with *P. gingivalis... περισσότερα »

Endoscopic Transcanal Retrocochlear Approach to the Internal Auditory Canal with Cochlear Preservation: Pilot Cadaveric Study
Contemporary operative approaches to the internal auditory canal (IAC) require the creation of large surgical portals for visualization with associated morbidity, including hearing loss, vestibular dysfunction, facial nerve injury, and skull base defects that increase the risk of cerebrospinal fluid leak. Transcanal approaches to the IAC have been possible only via a transcochlear technique. To preserve cochlear function, we describe a novel endoscopic transcanal infracochlear approach to the IAC in cadaveric temporal bones.

The lifecycles of apicomplexan parasites progress in accordance with fluxes in cytosolic Ca2+. Such fluxes are necessary for events like motility and egress from host cells. We used genetically-encoded Ca2+ indicators (GCaMPs) to develop a cell-based phenotypic screen for compounds that modulate Ca2+ signalling in the model apicomplexan Toxoplasma gondii. In doing so, we took […]

Microneme secretion is essential for motility, invasion, and egress in apicomplexan parasites. Although previous studies indicate that Ca2+ and cGMP control microneme secretion, little is known about how these pathways are naturally activated. Here we have developed genetically-encoded indicators for Ca2+ and microneme secretion to better define the signaling pathways that regulate these processes in […]

Expression of vascular endothelial growth factor (VEGF)-B and its receptor (VEGFR1) in murine heart, lung and kidney
Abstract Metabolic diseases, such as obesity and diabetes, are a serious burden for the health system. Vascular endothelial growth factor (VEGF)-B has been shown to regulate tissue uptake and accumulation of fatty acids and is thus involved in these metabolic diseases. However, the cell-type-specific expression pattern of *Vegfb* and its receptor (VEGFR1, gene *Flt1*) remains unclear. We explore the expression of *Vegfb* and *Flt1* in the murine heart, lung and kidney by utilizing β-galactosidase knock-in mouse models and combining the analysis of reporter gene expression and immu... περισσότερα »
A novel culture system for adult porcine intestinal crypts
Abstract Porcine models are useful for investigating therapeutic approaches to short bowel syndrome and potentially to intestinal stem cell (ISC) transplantation. Whereas techniques for the culture and genetic manipulation of ISCs from mice and humans are well established, similar methods for porcine stem cells have not been reported. Jejunal crypts were isolated from murine, human, and juvenile and adult porcine small intestine, suspended in Matrigel, and co-cultured with syngeneic intestinal subepithelial myofibroblasts (ISEMFs) or cultured without feeder cells in various cultur... περισσότερα »
