2006年2月16日 · Here, we employ flow cytometry and an anti-c-mpl monoclonal antibody to comprehensively define the surface expression pattern of c-mpl in four differentiation stages of human CD34+ HSC/PC (I: CD34+38--, II: CD34+38 dim , III: CD34+38+, IV: CD34 dim 38+) for the major sources of human HSC: fetal liver (FL), umbilical cord blood (UCB), adult bone ...

The thrombopoietin receptor also known as the myeloproliferative leukemia protein or CD110 (Cluster of Differentiation 110) is a protein that in humans is encoded by the MPL (myeloproliferative leukemia virus) oncogene.

The thrombopoietin receptor, also known as c-Mpl, is a member of the cytokine superfamily, which regulates the differentiation of megakaryocytes and formation of platelets by binding to its ligand, thrombopoietin (TPO), through Janus kinase (JAK)-signal transducer and activator of transcription (STA …

We developed a new conditional mouse model using c-Cbl fl/fl Pf4 Cre mice and demonstrated that platelet-specific knockout of c-Cbl led to severe microthrombocytosis and impaired uptake of TPO and c-MPL receptor internalization. Furthermore, we characterized a constitutive STAT5 activation c-Cbl KO platelets.

2024年8月14日 · Mutations in MPL, TPO, or Janus kinase 2 (JAK2) have been implicated in multiple diseases from congenital thrombocytopenias to myeloproliferative neoplasms. The ligand for MPL, TPO, stimulates platelet production by inducing MPL dimerization and results in an active conformation that allows downstream JAK2/STAT5 signaling.

2024年2月13日 · Thrombopoietin (TPO) and its receptor MPL play crucial roles in hematopoietic stem cell (HSC) function and platelet production. However, the precise effects of TPO/MPL signaling on HSC regulation in different hematopoietic niches remain unclear.

2018年5月13日 · The c-MPL-TPO axis regulates hematopoiesis by activating various signalling cascades, including JAK/STAT, MAPK/ERK, and PIK3/AKT. Here, we have summarized how TPO is regulated by c-MPL and, how mutations in the c-MPL regulate hematopoiesis. We also focus on its non-hematological regulatory role in d …

c-Mpl, a member of the hematopoietic cytokine receptor family, is the receptor for thrombopoietin. To investigate signal transduction by c-Mpl, a chimeric receptor, composed of the extracellular domain of human growth hormone receptor and the intracellular domain of c-Mpl, was introduced into the interleukin 3-dependent cell line Ba/F3.

Thrombopoietin (TPO) and the TPO-receptor (TPO-R, or c-MPL) are essential for hematopoietic stem cell (HSC) maintenance and megakaryocyte differentiation. Agents that can modulate TPO-R signaling are highly desirable for both basic research and clinical utility.

2021年1月12日 · Thrombopoietin (TPO) and the TPO-receptor (TPO-R, or c-MPL) are essential for hematopoietic stem cell (HSC) maintenance and megakaryocyte differentiation. Agents that can modulate TPO-R signaling are highly desirable for both basic research and clinical utility. We developed a series of surrogate pr …
