Schwann cells contribute to neurodegeneration in transthyretin amyloidosis.
2015
We established a spontaneously immortalized Schwann cell line derived from familial amyloidotic polyneuropathy transgenic mice. Conditioned medium from the cells contained variant transthyretin (TTR), and inhibited neurite outgrowth of neurons. TTR aggregates were observed in the Schwann cells and satellite cells of aged mice. Proteasome inhibition induced TTR aggregates as aggresomes in the cultured cells. These results support the hypothesis that Schwann cells contribute to neurodegeneration in familial amyloidotic polyneuropathy (FAP).
