Human eosinophils have been reported to express both the mRNA and protein for the high affinity IgE receptor (FcepsilonRI); it is speculated that this receptor plays a role in eosinophil mediator release in allergic diseases. However, questions still remain. How much of the FcepsilonRI protein is actually expressed on the cell surface of the eosinophil? If(More)
Tumorigenesis is a complex multistep process involving not only genetic and epigenetic changes in the tumor cell but also selective supportive conditions of the deregulated tumor microenvironment. One key compartment of the microenvironment is the vascular niche. The role of angiogenesis in solid tumors but also in hematologic malignancies is now well(More)
The low-affinity IgG Fc receptor, FcgammaRII (CD32), mediates various effector functions of lymphoid and myeloid cells and is the major IgG Fc receptor expressed by human eosinophils. We investigated whether FcgammaRII regulates both cell survival and death of human eosinophils. When cultured in vitro without growth factors, most eosinophils undergo(More)
BACKGROUND Eosinophils are selectively recruited into the tissues during chronic allergic inflammation. IgE is considered an initiator of the allergic reaction; however, the roles of IgE in allergic inflammation are not fully understood. OBJECTIVE We tested the hypothesis that antigen interaction with specific IgE antibody provokes eosinophilic(More)
