Abstract

Peroxisomes are organelles responsible for multiple metabolic pathways including, the biosynthesis of plasmalogens, a class of phospholipids, and the beta-oxidation of very-long-chain fatty acids (VLCFA). Lack of peroxisomes or dysfunction in any of their normal functions is the cellular basis for human peroxisomal disorders. Here we used mouse models to understand and define the biochemical and cellular determinants that mediate the pathophysiological consequences caused by peroxisomal dysfunctions. We investigated the role and effects of cellular plasmalogens and VLCFA accumulation in liver, testis and nervous tissue using Pex7 and Abcd1 knockout (KO) mice. In addition, we also generated a Pex7:Abcd1 double KO mouse to investigate how different peroxisomal dysfunctions modulate cellular function and pathology. We found that plasmalogens function as fundamental structural phospholipids and protect cells from damage caused by VLCFA accumulation. In testis, plasmalogens protect spermatocytes from VLCFA-induced degeneration and apoptosis. In nervous tissue, we found that gliosis, inflammatory demyelination and axonopathy caused by accumulation of VLCFA are modulated by plasmalogens. Our findings demonstrate the importance of normal peroxisomal functioning and allow the understanding of the pathological causality of peroxisomal dysfunctions. Nervous tissue deficient in plasmalogens is more prone to damage, illustrating the importance of plasmalogens in peroxisomal disorders including Zellweger syndrome and X-linked adrenoleukodystrophy.

  • VLCFA accumulation might cause demyelination by limiting peroxisomal synthesis of plasmalogens, notably plasmenyl-ethanolamine.

    “VLCFA accumulation might also cause demyelination by limiting peroxisomal synthesis of plasmalogens [261,262], notably plasmenyl-ethanolamine [261].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
