Functional overlap between ABCD1 (ALD) and ABCD2 (ALDR) transporters: a therapeutic target for X-adrenoleukodystrophy.

X-linked adrenoleukodystrophy (X-ALD) is a severe neurodegenerative disease caused by loss of function of the peroxisomal transporter ABCD1 (ALD), which results in accumulation of very long chain fatty acids (VLCFAs) in organs and serum, central demyelination and peripheral axonopathy and Addison's disease. Knockout of the ALD gene in the mouse (ALD(-)) results in an adrenomyeloneuropathy-like ...

Silencing of Abcd1 and Abcd2 genes sensitizes astrocytes for inflammation: implication for X-adrenoleukodystrophy.

X-linked adrenoleukodystrophy is a metabolic disorder arising from a mutation/deletion in the ABCD1 gene, leading to a defect in the peroxisomal adrenoleukodystrophy protein (ALDP), which inhibits the oxidation of very long chain fatty acids (VLCFAs). Thus, these VLCFAs accumulate. In a cerebral form of ALD (cALD), VLCFA accumulation induces neuroinflammation that leads to loss of oligodendrocy...

Mutations of ABCD1 gene and phenotype of Vietnamese patients with X-linked adrenoleukodystrophy (X-ALD)

X-linked adrenoleukodystrophy (X-ALD) is caused by a defect in the gene ABCD1, which maps to Xq28 and codes for a peroxisomal membrane protein that is a member of the ATP-binding cassette transporter superfamily. X-ALD is panethnic and affects approximately 1:20,000 males. This disease characterized by progressive neurologic dysfunction, occasionally associated with adrenal insufficiency. We ai...

Cholesterol regulates ABCD2 expression: implications for the therapy of X-linked adrenoleukodystrophy.

X-linked adrenoleukodystrophy (X-ALD) is a severe neurodegenerative disorder with impaired very long-chain fatty acid (VLCFA) metabolism. The disease-associated ABCD1 (ALD) gene encodes a peroxisomal membrane protein, which belongs to the superfamily of ATP-binding cassette transporters. Several treatment regimes have been tried without satisfactory clinical benefit. Recently, the cholesterol-l...

Pharmacological treatment based on gene redundancy: A novel therapeutic approach for X-linked adrenoleukodystrophy

X-linked adrenoleukodystrophy (X-ALD; OMIM 300100), the most frequent peroxisomal disorder, presents as a severe neurodegenerative disease with widely varying clinical phenotypes. The biochemical characteristic of X-ALD is the accumulation of very long-chain fatty acids (VLCFA), which should normally be degraded by the peroxisomal b-oxidation pathway, in plasma and tissues of X-ALD patients. It...
