Glomerular fibrosis has been shown to be closely related to the progression and
prognosis of IgA nephropathy (IgAN). However, mechanism underlying IgAN
glomerular fibrosis remains unclear. Recently, our study showed that plasma
gelsolin (pGSN) was decreased in the serum of an IgAN mouse model and that pGSN
deposition was found in the glomeruli. Another cytokine, TGF-?1, which is closely
related to glomerular fibrosis, was also found to be highly expressed in the
glomeruli. In the present study, we report that pGSN induces glomerular fibrosis
through the TGF-?1/Smads signal transduction pathway. This is supported by the
following findings: human mesangial cells (HMCs) show remarkable morphological
changes and proliferation in response to co-stimulation with pGSN and polymeric
IgA1 (pIgA1) from IgAN patients compared to other controls. Moreover, ELISA
assays showed that more TGF-?1 secretion was found in HMCs supernatants in the
co-stimulation group. Further experiments showed increased TGF-?1, Smad3,
p-Smad2/3, Smad4, and collagen 1 and decreased Smad7 expression in the
co-stimulation group. Our present study implied that the synergistic effect of
pGSN and pIgA induced glomerular fibrosis via the TGF-?1/Smads signal
transduction pathway. This might be a potential mechanism for the glomerular
fibrosis observed in IgAN patients.
