Expansion of EPOR-negative macrophages besides erythroblasts by elevated EPOR signaling in erythrocytosis mouse models
Activated erythropoietin (EPO) receptor (EPOR) signaling causes erythrocytosis. The important role of macrophages for the erythroid expansion and differentiation process has been reported, both in baseline and stress erythropoiesis. However, the significance of EPOR signaling for regulation of macrophages contributing to erythropoiesis has not been fully understood. Here we show that EPOR signa...
متن کاملUp-regulation of SLAP in FLI-1-transformed erythroblasts interferes with EpoR signaling.
Rearrangement of the FLI-1 locus and ensuing overexpression of FLI-1 protein is an early event in Friend murine leukemia virus (F-MuLV)-induced erythroleukemia. When overexpressed in primary erythroblasts, FLI-1 converts erythropoietin (Epo)-induced terminal differentiation into a proliferative response. We found that SLAP, a gene encoding a recently described negative regulator of T-cell antig...

system, a mechanism that reminds the mechanism of Fc receptor (FcR) blockade by opsonized red cells following anti-D immunoglobulin treatment.2 The decreased production of antiplatelet antibodies accounts for the late and sustained response. In late responders, the FcR blockade effect for some reason does not work, and we only see the late response. In conclusion, our results confirm that ritux...
متن کاملPolycythaemia-inducing mutations in the erythropoietin receptor (EPOR): mechanism and function as elucidated by epidermal growth factor receptor-EPOR chimeras.
Primary familial and congenital polycythaemia (PFCP) is a disease characterized by increased red blood cell mass, and can be associated with mutations in the intracellular region of the erythropoietin (EPO) receptor (EPOR). Here we explore the mechanisms by which EPOR mutations induce PFCP, using an experimental system based on chimeric receptors between epidermal growth factor receptor (EGFR) ...
متن کاملThe prolactin receptor rescues EpoR-/- erythroid progenitors and replaces EpoR in a synergistic interaction with c-kit.
We recently showed that a retrovirally transduced prolactin receptor (PrlR) efficiently supports the differentiation of wild-type burst-forming unit erythroid (BFU-e) and colony-forming unit erythroid (CFU-e) progenitors in response to prolactin and in the absence of erythropoietin (Epo). To examine directly whether the Epo receptor (EpoR) expressed by wild-type erythroid progenitors was essent...
