We used the HIM technology to investigate at nanometer scale resolution the ultrastructural alterations of the glomerular filtration apparatus in mice lacking the critical slit diaphragm-associated protein CD2AP, highlighting the great potential of HIM to provide new insights into the biology and (patho)physiology of glomerular diseases.
Two human patients with focal segmental glomerulosclerosis had a mutation predicted to ablate expression of one CD2AP allele, implicating CD2AP as a determinant of human susceptibility to glomerular disease.
Here we explored the role of nephrin and CD2AP together with the integrity of the slit diaphragm in the pathogenesis of proteinuria in patients with acquired glomerular diseases.
