Erythropoiesis and transferrin receptors
Current Opinion in Hematology, 2015The type 1 transferrin receptor (TfR1) is well known as a key player in erythroid differentiation through its role in iron uptake. Recently, it has been demonstrated that TfR1 could also have signaling functions in erythroid cells. Moreover, the second transferrin receptor, TfR2, whose signaling functions in hepatic cells are well established, was ...

AbstractTransferrin receptors (TfRs) are the conventional pathway by which cells acquire iron for physiological requirements. Under iron‐deficient conditions there is an increased concentration of surface TfR, especially on bone marrow erythroid precursors, as a mechanism to sequester needed iron.

Lymphoid receptors for transferrin
1987Publisher Summary Transferrin receptors present on the cell surface interact with this serum protein and provide a way in which iron can be specifically and vectorially transported through the plasma membrane. The transferrin receptor has proved to be an extremely useful system for the characterization of ligand/receptor interactions, receptor ...

Abstract The isolation and analysis of the transferrin receptor has been greatly aided by the use of monoclonal antibodies. The receptor is a disulphide-linked homo-dimer which spans the membrane and binds two molecules of transferrin. Controlling genes for this receptor in humans have been mapped to chromosome 3 using cell hybrids.

The Transferrin Receptor and the Release of Iron from Transferrin
1994In a classic report detailing the role of transferrin in providing iron to human reticulocytes, Jand1 and coworkers noted that uptake of transferrin-borne iron was saturable as the concentration of transferrin in the culture medium increased, and that uptake was essentially abolished if cells were first exposed to trypsin.

Relationship between Soluble Transferrin Receptors in Serum and Membrane-Bound Transferrin Receptors
Acta Haematologica, 1998The expression of transferrin receptors on the cell membrane of erythroblasts was analysed with flow cytometry in patients with different forms of anaemia. At the same time the concentration of soluble transferrin receptors (sTfRs) was analysed in serum. It was shown that only in iron deficiency a high concentration of sTfRs in serum could be explained

Transferrin receptors in the Parkinsonian midbrain
Neuropathology and Applied Neurobiology, 1994Several hypotheses have been put forward to explain the pathogenesis of Parkinson's disease (PD) and recently it has been suggested that alterations in iron homeostasis may be implicated. Because of the central role of the transferrin receptor in providing access of iron to cells, we have studied the distribution and density of transferrin receptors ...

Transferrin receptor in oral tumors
International Journal of Oral and Maxillofacial Surgery, 1994The transferrin receptor (TfR) appears in vigorously proliferating cells. We did an immunohistochemical study of TfR in oral tissues and a quantitative analysis by flow cytometry of TfR in a cancer cell line after an anticancer drug treatment. TfR was found in the parabasal and basal layers of the normal epithelium, but rarely in benign tumors ...

Diffusion of transferrin receptor clusters
Biophysical Chemistry, 1998Two dimensional motion of membrane receptors provides a mechanism for interaction among receptors in the plane of the membrane. In some cases the lateral diffusion leads to formation of clusters which may also be mobile. We have used image cross-correlation (ICCS) spectroscopy technique to measure the translational motion of transferrin receptors in ...
