The erythropoietin receptor (EpoR) is a protein that in humans is encoded by the EPOR gene. [5] EpoR is a 52 kDa peptide with a single carbohydrate chain resulting in an approximately 56–57 kDa protein found on the surface of EPO responding cells. It is a member of the cytokine receptor family. EpoR pre-exists as dimers.
Continuous erythropoietin receptor activator (CERA) is the generic term for drugs in a new class of third-generation erythropoiesis-stimulating agents (ESAs). In the media, these agents are commonly referred to as 'EPO', short for erythropoietin .
High level erythropoietin receptor expression is localized to erythroid progenitor cells. While there are reports that EPO receptors are found in a number of other tissues, such as heart, muscle, kidney and peripheral/central nervous tissue, those results are confounded by nonspecificity of reagents such as anti-EpoR antibodies. [11] In ...
SHP-1 is then able to bind and remove phosphate groups from the JAKs associated with receptors, preventing the transphosphorylation needed for the signalling pathway to progress. One example of this is seen in the JAK-STAT signalling pathway mediated by the erythropoietin receptor (EpoR).
Loss of function of the erythropoietin receptor or JAK2 in mice cells causes failure in erythropoiesis, so production of red blood cells in embryos and growth is disrupted. If there is no systemic feedback inhibition, for example, the diminishment or absence of suppressors of cytokine signaling proteins, giantism may result as shown in mice models.
Erythropoietin and its receptor were thought to be present in the central nervous system according to experiments with antibodies that were subsequently shown to be nonspecific. While erythropoietin alpha is capable of crossing the blood brain barrier via active transport, [1] concentrations in the central nervous system are very low. The ...
So, she discussed the option of going on Mounjaro, a GLP-1 receptor agonist, with her doctor in November of 2022. Her doctor was on board, ...
Methoxy polyethylene glycol-epoetin beta, sold under the brand name Mircera, is a long-acting erythropoietin receptor activator (CERA) used for the treatment of anaemia associated with chronic kidney disease. [4] It is the first approved, chemically modified erythropoiesis-stimulating agent (ESA). [citation needed]
