Vertical Si p-MOSFETs with channel lengths of 100nm were fabricated using selective low pressure chemical vapour deposition (LPCVD) epitaxial growth and conventional i-line lithography. The layout, called VOXFET, reduces gate to source/drain overlap capacitances, thus improving high speed applications. Transistors with a gate width of 12 um and gate oxide thickness of 10nm show transconductances gM of 200mS/mm and measured cutoff frequencies of fT = 8.7GHz and fMAX = 19.2 GHz. [less ▲]

1alpha,25-Dihydroxyvitamin D3 is a potent suppressor of interferon gamma-mediated macrophage activation.

1alpha,25-Dihydroxyvitamin D3 (1alpha,25(OH)2D3), the activated vitamin D3 hormone, is a key regulator of calcium homeostasis and thereby indispensable for bone metabolism. In addition, 1alpha,25(OH)2D3 is known to mediate predominantly immunosuppressive responses in vitro and in vivo. It has been demonstrated that macrophages can produce 1alpha,25(OH)2D3 on activation with interferon gamma (IFN-gamma), although little is understood about the biologic significance of this response. We show here that 1alpha,25(OH)2D3 can selectively suppress key effector functions of IFN-gamma-activated macrophages. Among these are the suppression of listericidal activity, the inhibition of phagocyte oxidase-mediated oxidative burst, and the suppression of important IFN-gamma-induced genes, including Ccl5, Cxcl10, Cxcl9, Irf2, Fcgr1, Fcgr3, and Tlr2. The deactivation of IFN-gamma-stimulated macrophages is dependent on a functional vitamin D receptor and 1alpha,25(OH)2D3 acts specifically on IFN-gamma-activated macrophages, whereas the steroid has no effects on resting macrophages. Therefore, the 1alpha,25(OH)2D3-mediated suppression of macrophage functions is distinct from previously described macrophage deactivation mechanisms. In conclusion, our data indicate that the production of 1alpha,25(OH)2D3 by IFN-gamma-stimulated macrophages might be an important negative feedback mechanism to control innate and inflammatory responses of activated macrophages.
