Nephrosis Nephrosis Nephrosis is any of various forms of kidney disease (nephropathy). In an old and broad sense of the term, it is any nephropathy, but in current usage the term is usually restricted to a narrower sense of nephropathy without inflammation or neoplasia, in which sense it is distinguished from nephritis, which involves inflammation. It is also defined as any purely degenerative disease of the renal tubules. Nephrosis is characterized by a set of signs called the nephrotic syndrome. Nephrosis can be a primary disorder or can be secondary to another disorder. Nephrotic complications of another disorder can coexist with
Wallerian degeneration attributed to the ErbB2 receptors and the ErbB3 receptors. This proliferation could further enhance the myelin cleaning rates and plays an essential role in regeneration of axons observed in PNS. Schwann cells emit growth factors that attract new axonal sprouts growing from the proximal stump after complete degeneration of the injured distal stump. This leads to possible reinnervation of the target cell or organ. However, the reinnervation is not necessarily perfect, as possible misleading occurs during reinnervation of the proximal axons to target cells. In comparison to Schwann cells, oligodendrocytes require axon signals to survive. In their developmental stages, oligodendrocytes
