    Applications
    The FCGRT gene, which encodes the neonatal Fc receptor (FcRn), has been studied in various contexts. In primary human vascular endothelial cells, FcRn is involved in the trafficking of albumin, contributing to albumin homeostasis. FcRn-albumin complexes are internalized and transported in acidic endosomal structures, and wildtype albumin is excluded from late endosomes and/or lysosomes. FcRn-positive tubules derived from maturing macropinosomes transport albumin towards the plasma membrane. In the context of antithrombin, protein C, and protein S, genome-wide association studies have identified novel loci regulating plasma levels of these proteins. One of these loci is the FCGRT gene, which is associated with antithrombin levels. Additionally, epigenetic control of CD1D expression, a gene involved in antigen presentation, has been identified as a mechanism of resistance to immune checkpoint therapy in melanomas. FCGRT is one of the genes found to be associated with CD1D expression. Finally, in neonatal buffalo calves, genetic variation in the FCGRT gene is associated with serum IgG levels, potentially impacting the transfer of passive immunity. Overall, FCGRT plays a role in albumin homeostasis, plasma protein regulation, immune checkpoint therapy resistance, antigen presentation, and passive immunity transfer.

    Can FCGRT be a prognostic factor for glioma? Jun 24 2020

    chat Patrick Liam (Creative Biolabs Scientific Support)

    FCGRT is believed to be an independent prognostic factor for glioma patients, possibly by promoting tumor cell proliferation and invasion. Jun 24 2020

    Published Data

    Research Highlights

    Pannek, Andreas. et al. "The endosomal system of primary human vascular endothelial cells and albumin-FcRn trafficking." Journal of cell science, 2023.
    In the study, the researchers aimed to investigate the trafficking of FcRn-albumin complexes in primary human endothelial cells. The authors generated primary human vascular endothelial cell lines, known as blood outgrowth endothelial cells (BOECs), from blood endothelial precursors. They mapped the endosomal system in BOECs and observed that fluorescently labelled HSA was efficiently internalised primarily through fluid-phase macropinocytosis. The study also showed that HSA molecules co-localised with FcRn in acidic endosomal structures and that wildtype HSA, but not the non-FcRn-binding HSAH464Q mutant, was excluded from late endosomes and/or lysosomes. Live imaging revealed that FcRn-positive tubules derived from maturing macropinosomes transport HSA towards the plasma membrane. These findings provide insights into the FcRn-albumin trafficking pathway in primary vascular endothelial cells, with implications for albumin homeostasis.

    The natural anticoagulant proteins antithrombin, PC (protein C), and PS (protein S) play a crucial role in regulating hemostasis and have been linked to venous thromboembolism when their levels are partially deficient. However, previous genetic association studies investigating these proteins were hindered by small sample sizes or limited to specific genes. Through a collaboration with the Cohorts for Heart and Aging Research in Genomic Epidemiology consortium, 10 genome-wide association studies were conducted across different ancestries to meta-analyze the results of plasma levels of these proteins.
