Molecular Insights into the Pathogenesis of IgA Nephropathy.
Paris, France. In Trends Mol Med, Dec 2015
To date, three key molecules have been implicated in IC formation, correlating with disease progression/recurrence after transplantation: galactose-deficient IgA1 (Gd-IgA1), IgG anti-Gd-IgA1 antibodies, and soluble CD89 (an Fc receptor for IgA).
Role of IgA receptors in the pathogenesis of IgA nephropathy.
Paris, France. In J Nephrol, Dec 2015
Quantitative and structural changes of Gd-IgA1 play a key role in the development of the disease due to functional abnormalities of two IgA receptors: the FcαRI (CD89) expressed by blood myeloid cells and the transferrin receptor (CD71) on mesangial cells.
Gluten and IgA nephropathy: you are what you eat?
Leicester, United Kingdom. In Kidney Int, Aug 2015
Using a double transgenic mouse model of IgA nephropathy that expresses both human IgA1 and human CD89, Papista et al. report that a gluten-free diet protects against the development of IgA deposition and glomerular injury, and that these events occur with the introduction of dietary gluten.
IgA, IgA receptors, and their anti-inflammatory properties.
Paris, France. In Curr Top Microbiol Immunol, 2013
IgA functions mainly through interaction with multiple receptors including IgA Fc receptor I (FcαRI), transferrin receptor 1 (CD71), asialoglycoprotein receptor (ASGPR), Fcα/μR, FcRL4, and DC-SIGN/SIGNR1.
IgA Fc receptors.
Paris, France. In Annu Rev Immunol, 2002
The IgA receptor family comprises a number of surface receptors including the polymeric Ig receptor involved in epithelial transport of IgA/IgM, the myeloid specific IgA Fc receptor (FcalphaRI or CD89), the Fcalpha/muR, and at least two alternative IgA receptors.
