abstract：:Electron-dense granules (EDGs) are singular structures found in the tissues of several vertebrate and invertebrate organisms. Two types of EDGs were observed in hepatopancreatic cells of the crab Ucides cordatus: (1) a non-mineralized EDG, found mainly inside vacuoles, which reacted positively to acid phosphatase and ...

abstract：:CD4+CD25+(high) regulatory T cells (Tregs) play a pivotal role in the control of the immune response. A growing body of evidence suggests the reduced function of these cells in autoimmune diseases, including type 1 diabetes (T1D). Restoration of their function can potentially delay further disease development. In the ...
