abstract = {Neuronal ceroid lipofuscinosis (NCL) comprises ∼13
genetically distinct lysosomal disorders primarily affecting
the central nervous system. Here we report successful
reprograming of patient fibroblasts into induced pluripotent
stem cells (iPSCs) for the two most common NCL subtypes:
classic late-infantile NCL, caused by TPP1(CLN2) mutation,
and juvenile NCL, caused by CLN3 mutation. CLN2/TPP1- and
CLN3-iPSCs displayed overlapping but distinct biochemical
and morphological abnormalities within the
endosomal-lysosomal system. In neuronal derivatives, further
abnormalities were observed in mitochondria, Golgi and
endoplasmic reticulum. While lysosomal storage was
undetectable in iPSCs, progressive disease subtype-specific
storage material was evident upon neural differentiation and
was rescued by reintroducing the non-mutated NCL proteins.
In proof-of-concept studies, we further documented
differential effects of potential small molecule TPP1
activity inducers. Fenofibrate and gemfibrozil, previously
reported to induce TPP1 activity in control cells, failed to
increase TPP1 activity in patient iPSC-derived neural
progenitor cells. Conversely, nonsense suppression by PTC124
resulted in both an increase of TPP1 activity and
attenuation of neuropathology in patient iPSC-derived neural
progenitor cells. This study therefore documents the high
value of this powerful new set of tools for improved drug
screening and for investigating early mechanisms driving NCL
pathogenesis.},
