Among different goals defined in vehicle design process, fuel consumption (FC) is one of the most important objectives, which significantly has taken into account lately, both by the customers and vehicle manufacturers. One of the significant parameters which impacts the vehicle FC is the efficiency of vehicle's power train. In this paper, a half-toroidal continuously variable transmission (CVT...

Fc receptors (Fc R) trigger inflammatory reactions in response to immunoglobulinopsonized pathogens and antigen-antibody complexes. The coordinate expression of activating and inhibitory Fc R ensures the homeostasis of immune complex-driven inflammatory responses. In this study, we used antibodies with preferential binding for activating Fc RIIa and inhibitory Fc RIIb receptors to investigate t...

The involvement of Fc- and Fc+ T cells, separated on the fluorescence-activated cell sorter, in proliferative and cytotoxic responses to alloantigens was examined. The cytotoxic lymphocytes generated by in vivo exposure to allogeneic tumor cells were shown to express the Fc receptor. The proliferative responses to alloantigen exposure in mixed lymphocyte cultures was equivalent in intensity for...

In addition to their well characterized high affinity immunoglobulin E (IgE) receptors (Fc epsilon RI) mast cells have long been suspected to express undefined Fc receptors capable of binding IgE with low affinity. In this paper, we show that Fc gamma RII and Fc gamma RIII, but not Mac-2, on mouse mast cells and macrophages bind IgE-immune complexes. This binding is efficiently competed by 2.4G...

The responsiveness of purified Fc- and Fc+ T lymphocytes, isolated from normal spleen cell populations by cell sorting on the fluorescence activated cell sorter, has been examined. Although both Fc- and Fc+ T cells responded to phytohemagglutinin, the response to concanavalin A (Con A) was found to be a characteristic of the Fc+ T lymphocyte. The poor responsiveness of the Fc- T cells to Con A ...

Rationale: Elevations in C-reactive protein (CRP) are associated with increased cardiovascular disease risk and endothelial dysfunction. CRP antagonizes endothelial nitric oxide synthase (eNOS) through processes mediated by the IgG receptor Fc receptor IIB (Fc RIIB), its immunoreceptor tyrosine-based inhibitory motif, and SH2 domaincontaining inositol 5 -phosphatase 1. In mice, CRP actions on e...

Bone morphogenetic proteins (BMPs) are multi-functional growth factors that belong to the TGF-beta superfamily. Recently, several soluble BMP receptors, such as ActRIIA-Fc, ActRIIB-Fc, and ALK1-Fc, are undergoing clinical trials. Both BMPRIA and BMPRIB are type I BMP receptors, and while BMPRIA-Fc has been reported to have bone-increasing properties, there have been no investigations concerning...
