Endothelial and mesangial cells were positively identified from the early cultures (up to 10 days) with antibodies to a 350 kD protein, dipeptidyl peptidase IV, podocalyxin, factor VIII, OX-43 and with Bandeiraea simplicifolia (BS-I B4) lectin, and with antibodies to smooth muscle actin, desmin, Thy1.1 antigens and with Ricinus communis (RCA-1) lectin, respectively.

The cytoskeletal linking proteins, moesin and radixin, are upregulated by platelet-derived growth factor, but not basic fibroblast growth factor in experimental mesangial proliferative glomerulonephritis.

|
The expression of the two cytoskeletal linking proteins, moesin and radixin, was examined in experimental mesangial proliferative nephritis in rats (anti-Thy1 model).

|
Moesin and radixin mRNA and protein are constitutively expressed in all cell types of normal rat glomeruli, except podocytes.
|

|
In the anti-Thy1 model the expression of moesin and radixin was increased in infiltrating macrophages and in activated, alpha-smooth muscle actin-positive mesangial cells and was concentrated in the cellular extensions of mesangial cells in areas of glomerular remodelling.

|
Studies using neutralizing antibodies demonstrated that the increase in moesin and radixin expression by mesangial cells is mediated by PDGF, but not bFGF.
|

|
The increase in these cytoskeletal proteins appears to be regulated primarily (radixin) or partially (moesin) posttranscriptionally.
|

|
The data suggest that PDGF mediated upregulation of the cytoskeletal proteins, moesin and radixin, is important for cell migration and other changes that accompany the coordinated restoration of glomerular architecture after injury.

Cell injury in podocytes (evidenced as increased expression of desmin and by electron microscopy) and interstitial fibroblasts (increased expression of alpha-smooth muscle actin) and mild glomerular hypertrophy were witnessed as early as three to four months of age and preceded glomerulosclerosis and interstitial fibrosis.
|

|
Only minor evidence of mesangial cell activation (as assessed by glomerular (de novo alpha-smooth muscle actin or type I collagen expression or increased cell proliferation) was noted throughout the observation period.

In all of the healthy subjects and all of the patients except those with PGN (disease control subjects), VPF/VEGF protein and mRNA were detected mainly in podocytes.
|
| 14 |

|
However, in some PGN patients, VPF/VEGF protein was demonstrated clearly in MC as well as in podocytes, as some of the VPF/VEGF was colocalized with alpha-smooth muscle actin, a marker of activated MC, and VPF/VEGF mRNA was expressed by MC and podocytes.

|
The time between biopsy and disease onset was significantly shorter in PGN patients with than in those without mesangial VPF/VEGF expression (P < 0.01).

Augmentation of kidney injury by basic fibroblast growth factor or platelet-derived growth factor does not induce progressive diabetic nephropathy in the Goto Kakizaki model of non-insulin-dependent diabetes.
|

|
Specifically, we examined whether the administration of either platelet-derived growth factor (PDGF) or basic fibroblast growth factor (bFGF) in sub-nephritogenic doses might lead to an aggravation of kidney structural changes associated with hyperglycemia, resulting in progressive kidney damage in the Goto Kakizaki (GK) rat, which is a genetic model of non-obese non-insulin-dependent diabetes mellitus (NIDDM), in which progressive kidney disease does not develop spontaneously.

|
The results demonstrate that the administration of PDGF to hyperglycemic GK rats led to acute mesangial cell proliferation and activation as assessed by 5-bromo-2'-deoxyuridine-positive nuclei and immunostaining for alpha-smooth muscle actin.

Immunohistochemical studies showed increased fibronectin and desmin expression in glomeruli and tubulointerstitium and increased vimentin and alpha-smooth muscle actin in the tubulointerstitial area from the renal cortex of RT18 rats (P: < 0.05).
