Expression of Nutrient Transporters on NK Cells During Murine ...
May 2, 2021 · The most widely investigated nutrient transporters on immune cells are CD71, the transferrin receptor and CD98 (SLC3A2), a chaperone that forms a heterodimeric system L-amino acid transporter by pairing mainly with SLC7A5 (LAT-1) in NK cells (3, 6, 7, 10 – 12).
The Usefulness of CD71 Expression by Flow Cytometry in the …
Nov 16, 2012 · CD71 (transferring receptor 1) is an integral membrane glycoprotein that plays an important role in cellular uptake of iron. It is well known as a marker for cell proliferation and activation. Although all proliferating cells in hematopoietic system express CD71, however, CD71 has been considered as a useful erythroid-associated antigen.
Metabolic flexibility determines human NK cell functional fate in …
Jun 1, 2021 · In this study, we investigated the mechanisms for human NK cell dysfunction in the TME. Using models of human ovarian cancer, we found that the TME directly paralyzes NK cell glucose metabolism via lipid-peroxidation-associated …

Jun 14, 2018 · Consistent with normal cMyc expression, NK cells stimulated in the presence of Akti-1/2 were equivalent in size and CD71 expression, and produced comparable levels of IFNγ and granzyme B...
Role of CD71 in acute leukemia- An immunophenotypic marker …
CD71 expression has been found to be significantly increased in rapidly proliferating cells. Methods: This cross-sectional study included 37 bone marrow samples of acute leukemia cases diagnosed between October 2016 to April 2018. The samples were analysed on BD FACS Canto II.
Identification of Anti-tumor Cells Carrying Natural Killer (NK) Cell ...
We found a population of highly activated CD56 dim CD16 + NK cells that have recently degranulated, evidence of killing activity, and it is absent in healthy donors.
Expanded human NK cells armed with CAR uncouple potent anti …
Jun 25, 2021 · Our recent work has shown that higher expression of the amino acid transporter CD98 and CD71 transferrin receptor does correlate with enhanced NK cell anti-tumor function (Poznanski et al., 2021a). This suggests that NK cells transduced with the control vector may have heightened nutrient uptake capacity leading to some level of non-specific ...
Cluster of Differentiation 71 (CD71) - SpringerLink
Mar 11, 2016 · Cluster of Differentiation 71 protein (CD71), also known as the Transferrin receptor protein 1 (TfR1) is a protein encoded by the TFRC gene located on chromosome 3q29. It is found as a cell surface membrane protein in humans and is essential for iron delivery to the cells.
