Abstract
We examined the role of Mag, an autoimmune susceptibility locus encoded by the telomeric region of MRL/MpJ mouse chromosome 1, in the pathogenesis of autoimmune exocrinopathy. At nine to 12 months of age, strain-specific differences were observed in the pancreas of the animals. B- and T-cell-containing periductal/perivascular cell infiltrations in the pancreases of MRL/MpJ and B6.MRLc1 congenic C57BL/6-background Mag-carrying strains were more severe than were those of C57BL/6. Pancreatic periductal/perivascular cell infiltration was observed frequently in A/J, AKR/N, B6.MRLc1, C57BL/6, and MRL/MpJ, moderately in DBA/1 and DBA/2, and rarely in BALB/c and C3H/He strains. Females tended to have greater pancreatic periductal/perivascular cell infiltration than males. C57BL/6 mice possessed defined borders between cell infiltrations and acini, but borders were indistinct in MRL/MpJ and B6.MRLc1 mice. We attributed this to the invasion of inflammatory cells between each acinus and the disruption of acinar cells around cell infiltrations in the latter strains. No strain-specific differences were observed in the appearance of fibrotic lesions and high endothelial venules in the cell infiltrates. The levels of serum anti-dsDNA antibodies and amylase, and mRNA expression of tumor necrosis factor-α and Fc gamma receptor III (encoded on Mag) in the pancreases, were elevated in MRL/MpJ- and B6.MRLc1-strain mice relative to C57BL/6. These results emphasized the crucial roles of Mag in the molecular and genetic pathogenesis of autoimmune-mediated pancreatitis.

Abstract
The autoimmune-prone BXSB/MpJ-Yaa mouse is a model of membranous proliferative glomerulonephritis (MPGN). Severe MPGN has been reported only in male BXSB/MpJ-Yaa mice because of the Y-linked autoimmune accelerator (Yaa) locus. However, we show that female BXSB/MpJ mice develop age-related MPGN without Yaa. Female BXSB/MpJ mice clearly developed MPGN characterized by increased mesangial cells, thickening of the glomerular basement membrane (GBM), double contouring and spike formation of GBM with T-cell infiltrations and podocyte injuries corresponding with increased autoantibody production and albuminuria. Analysis of the renal levels of the Fc gamma receptor (Fcgr) and interferon-activated gene 200 (Ifi200) family genes, which are MPGN candidate genes localized to the telomeric region of chromosome 1 (Chr.1), showed that Fcgr2b levels decreased, whereas Fcgr3 and Ifi202b levels increased in female BXSB/MpJ mice compared with healthy C57BL/6 mice. Furthermore, in isolated glomeruli, microarray analysis revealed that Fcgr3, Fcgr4 and Ifi202b expression was higher in male BXSB/MpJ-Yaa mice than in male BXSB/MpJ mice. These findings indicate that the BXSB/MpJ-type genome causes age-related MPGN with significant contribution from the telomeric region of Chr.1, and Yaa enhances the expression of genes localizing to this locus, thereby leading to severe MPGN in male mice.

Abstract
Previously, the structure of the adult goat parotid salivary glands (PGs) was studied. However, little information was elucidated of the juvenile ones. This study aimed to clarify the correlations between the structure of goats' PGs and the nature of food intake among milk-suckling kids (MSKs) and diet-fed goats (DFGs). The secretory endpieces of the goats' PGs are of the pure serous type. The serous cells in MSKs showed apical accumulation of numerous secretory granules (SGs) of smaller size and of more intense positive periodic acid-Schiff reaction. Ultrastructurally, most of the SGs in the DFGs contained peripherally located inclusions that showed dense reaction products for acid phosphatase. In MSKs, the PGs showed less-developed basal infoldings, sparseness of the inter-cellular inter-digitations, fewer inter-cellular canaliculi and microvilli and also less-developed myoepithelial cells with fewer and shorter cytoplasmic processes. In conclusion, the less-developed membrane specializations and myoepithelial cells, as well as the accumulated SGs in the PGs of MSKs, suggest that it secretes less saliva with a little secretory activity than that of DFGs, which may be correlated with the reduced masticatory activity.
