IgG4-related disease: why high IgG4 and fibrosis?
Abstract:
The hallmarks of IgG4-related disease (IgG4-RD) are lymphoplasmacytic tissue infiltration with a predominance of IgG4-positive plasma cells, accompanied by fibrosis, obliterative phlebitis, dacryoadenitis, and elevated levels of IgG4. In a recent issue of Arthritis Research & Therapy, Tsuboi and colleagues demonstrated that regulatory T (Treg) cell-and T helper 2 (Th2) cell-derived cytokines contribute to the pathogenesis of Mikulicz's disease, an activation pathway that appears to be common for IgG4-RD. Additional organ-specific factors may account for the different organ involvement of IgG4-RD.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
