a-Lipoic acid (α-LA) is a neuroprotective metabolic antioxidant that has been shown to cross the blood brain barrier. We tested whether a-LA is capable to prevent MOG35–55-induced experimental autoimmune encephalomyelitis (EAE), an established model of multiple sclerosis (MS). Daily oral administration of a-LA, starting at the time of immunization, significantly prevented EAE progression as compared to control mice.
Abstract
The study investigates if alpha-lipoic acid is neuroprotective against chemo induced neurotoxicity, if mitochondrial damage plays a critical role in toxic neurodegenerative cascade, and if neuroprotective effects of alpha-lipoic acid depend on mitochondria protection.
We used an in vitro model of chemo induced peripheral neuropathy that closely mimic the in vivo condition by exposing primary cultures of dorsal root ganglion (DRG) sensory neurons to paclitaxel and cisplatin,
Alpha-lipoic acid (LA), the metabolic antioxidant, was evaluated for its potential to protect against Cr6+-induced DNA damage. Potassium dichromate was administered to Swiss albino mice orally ad libitum at the doses of 5, 10 or 25 mg/kg body weight in drinking water to set DNA damage in cells, which was characterized in mouse peripheral blood mononuclear cells and bone marrow cells using single-cell gel electrophoresis and analyses of generated comets for Tail moment,
The authors describe the long-term survival of a patient with pancreatic cancer without any toxic adverse effects. The results regimen includes the intravenous alpha-lipoic acid and low-dose naltrexone (ALA-N) protocol and a healthy lifestyle program. The patient was told by a reputable university oncology center in October 2002 that there was little hope for his survival.
Abstract Alpha-lipoic acid has been shown to possess cancer-cell-killing activity via activation of the apoptosis pathway. In this study, the cytotoxic activities of alpha-lipoic and dihydro-alpha-lipoic acid were compared in HL-60 cells. The cell-killing activity of dihydro-alpha-lipoic acid was higher than that of alpha-lipoic acid. Both alpha-lipoic and dihydro-alpha-lipoic acid induced caspase-3 cleavage and internucleosomal DNA fragmentation in treated cells.
Abstract
The anti-oxidant lipoic acid (LA) potently suppresses clinical and pathologic disease in the animal model of multiple sclerosis, experimental autoimmune encephalomyelitis, by inhibiting the migration of pathogenic T cells to the spinal cord. The mechanism by which this occurs is largely unknown. In this report we demonstrate that LA induces increases in cyclic AMP,
Aims
Alpha-lipoic acid (LA) is a commonly used dietary supplement that exerts anti-oxidant and anti-inflammatory effects in vivo and in vitro. We investigated the mechanisms by which LA may confer protection in models of established atherosclerosis.
Main methods
Watanabe heritable hyperlipidemic (WHHL) rabbits were fed with high cholesterol chow for 6 weeks and then randomized to receive either high cholesterol diet alone or combined with LA (20 mg/kg/day) for 12 weeks.
