CD44 is required for the pathogenesis of experimental crescentic glomerulonephritis and collapsing focal segmental glomerulosclerosis

Abstract: A key feature of glomerular diseases such as crescentic glomerulonephritis and focal segmental glomerulosclerosis is the activation, migration and proliferation of parietal epithelial cells. CD44-positive activated parietal epithelial cells have been identified in proliferative cellular lesions in glomerular disease. However, it remains unknown whether CD44-positive parietal epithelial cells contribute to the pathogenesis of scarring glomerular diseases. Here, we evaluated this in experimental crescentic glome… Show more

“…De novo expression of CD44 is an established marker for PEC activation, 4,8,9 and modulation of CD44 signaling attenuates the development of glomerulosclerotic lesions. 10,11 In FSGS, activated PECs and podocytes form cellular adhesions (synechiae) between Bowman's capsule and the glomerular tuft. 12 Via this process, they are the earliest defining lesions for subsequent development of sclerotic lesions and FSGS.…”

“…2,[11][12][13] Also, various signaling pathways and receptors underlie the altered PEC behavior in glomerular diseases. 5,6,4,14,15 Nevertheless, a major knowledge gap has been identifying the molecular processes driving the switch from a quiescent to an active PEC state. The study by Lazareth et al unequivocally demonstrates that CD9 is a major regulator of PEC activation.…”

“…Mice deficient in CD44 have reduced capacity for PEC proliferation in models of both crescentic glomerulonephritis and FSGS. 3 In this issue, Kuppe et al 4 now turn their attention to the previously underrecognized third region of Bowman's capsule-the peritubular region. Here cuboidal cells labeling as PECs (cPECs) share morphological features with proximal tubular cells.…”
