The second series of experiments was designed to study the effects of FGF2 neutralizing antibody (40 micrograms for 5 days after PAN injection, in MoAb group) on severely damaged podocytes caused by repeated (two courses) injections in the PAN nephropathy rats.
We have detected high levels of bFGF accumulated in the kidney of HIV-transgenic mice and in children with HIV-associated renal diseases and the hemolytic uremic syndrome (HUS).
In addition, we found that FGF-2 induces a similar increase in the attachment of HIV-infected PBMCs and monocytes/macrophages to plastic tissue culture dishes and to monolayers of primary renal tubular epithelial cells harvested from the urine of HIV-infected children with renal disease.
Furthermore, the upregulation of FGF-BP by regenerating renal tubular epithelial cells may provide a mechanism by which the regenerative and angiogenic activity of FGF-2 in renal capillaries can be modulated in children with HIV-HUS and other renal disease.
