Glomerular hypertension, abnormal glomerular growth, and progression of renal diseases.
The development and progression of sclerosis is determined by complex interactions of many mechanisms, including direct hemodynamic actions, modulation of glomerular cell injury, and growth factor actions. The interplay of these factors determines the balance of cell growth and proliferation versus cell death by necrosis or apoptosis, and the balance of matrix accumulation versus degradation. Sclerosis may even be reversed when therapies inhibit these mechanisms and augment matrix degradation processes, both by directly increasing proteolytic activity and by down-regulating inhibitors of matrix degradation. We will focus in this review on the roles of glomerular hemodynamics and growth in the progression of renal diseases.
