Project description:A missense mutation in TFRC, encoding transferrin receptor 1, causes combined immunodeficiency (Family A)
| PRJNA303985 | ENA
Project description:TFRC, also known as CD71, regulates the uptake of transferrin-bound iron into cells through receptor-mediated endocytosis. In a patient with a combined immunodeficiency, we identified a homozygous missense mutation in TFRC gene leading to R22W amino acid change in the cytoplasmic tail of the receptor. This mutation impairs the endocytosis of TFRC, which results in profound aberrations in the immune system.

Project description:the same population of EPCs was detected in bladder cancer patients. The EPCs, whose function could be reversed via anti-CD71 treatment, were induced by the circRNA TFRC (circular RNA derived from the transferrin receptor mRNA; cTFRC) in bladder cancer exosomes.

Project description:An IRF4 de novo mutation affecting the DNA binding domain of encoded IRF4 protein (mutDBD) was identified in a patient presenting with combined immunodeficiency. The patient exhibited profound susceptibility to opportunistic infections notably Pneumocystis jirovecii and humoral immunodeficiency caused by a failure of terminal B cell differentiation. A heterozygous IRF4 missense variant resulting in a phenylalanine-to-leucine replacement within the interferon activation domain of the encoded IRF4 protein (mutIAD) was identified in three patients from a multigenerational family suffering from a novel autosomal dominant disease predominantly presenting as a hypogammaglobulinemia with recurrent infections. In this experiment we aimed to investigate the effect of the two different mutations on IRF4 genomic binding.

Project description:We investigated the ability of transferrin receptor1 (TfRc) knockout cells to populate different domains of the developing kidney by using a chimeric approach. The TfRc cells developed into all segments of the developing nephron, but there was a relative exclusion from the ureteric bud and a positive bias towards the stromal compartment. Here we conducted a microarray analysis of differential gene expression between TfRc deficient and wild type (wt) cells in chimeric embryonic kidneys derived from embryos created by blastocyst injection of wt blastocysts with TfRc-/- green fluorescent protein-expressing (GFP+) embryonic stem cells. Experiment Overall Design: Following blastocyst injection of 3-5 TfRc-/- GFP+ embryonic stem cells in wt blstocysts, we harvested the chimeric kidney at day E15.5 and separated the TfRc-/- GFP+ cell population from wt GFP- cell population by using fluorescence activated cell sorting. Biotinlyated cRNA was prepared from the isolated cells and hybridized to Mouse Genome 430 2.0 Arrays (Affymetrix) according to standard protocols.
