Not exact matches

Using samples from the Dominantly Inherited Alzheimer Network (DIAN) study, the researchers found that people who carried the mutation responsible for this form of Alzheimer's also had altered levels of specific lipids in their blood plasma compared to the control group.

The Freiburg team of Shastri, Dr. Shengnan Xiang and Dr. Melika Sarem, have now discovered that liposomes — nanoscale vesicles of lipid molecules encompassing an aqueous core — can be used to alter the stiffness of the cell plasma membrane through lipid transfer.

Liposuction did not significantly alter the insulin sensitivity of muscle, liver, or adipose tissue (assessed by the stimulation of glucose disposal, the suppression of glucose production, and the suppression of lipolysis, respectively); did not significantly alter plasma concentrations of C - reactive protein, interleukin - 6, tumor necrosis factor alpha, and adiponectin; and did not significantly affect other risk factors for coronary heart disease (blood pressure and plasma glucose, insulin, and lipid concentrations) in either group.

Aβ is believed to penetrate neuronal plasma membranes, where it leads to lipid peroxidation.10 It has also been implicated in deactivating a subunit of the pyruvate dehydrogenase complex, thereby inhibiting conversion of pyruvate to acetyl CoA and the eventual production of cellular energy as ATP.32 Another way Aβ affects glucose metabolism in the brain is that fragments of Aβ disrupt insulin signaling by binding to neuronal synapses, which alters their shape and function.15, 38 Insulin receptors are abundant at synapses, so if the integrity of the synapse itself has been compromised, the receptors won't function effectively.

«We looked at about 4,600 metabolites and discovered that 10 lipids were significantly altered in the plasma of cognitively normal older adults who would go on to develop the clinical symptoms of Alzheimer's disease.
