yes ,u got it right.That s lipoid nephrosis,abnormal secretion of lymphokines by T cells is thought to reduce the production of anions in the glomerular basement membrane, thereby increasing the glomerular permeability to plasma albumin through a reduction of electrostatic repulsion.Then u have foot process fusion
