Whether a patient receives whole blood, red cells, platelets or plasma, this lifesaving care starts with one person making a generous donation.

Sickle cell patients can require blood transfusions throughout their lives.

Many of them will need blood, sometimes daily, during their chemotherapy treatment.

Because only 7 of people in the U.S.

O negative, its always in great demand and often in short supply.

Since only 3 of people in the U.S.

AB positive blood, this plasma is usually in short supply.

Mitochondrial alterations have been reported in several neurodegenerative disorders, including Alzheimers disease (AD), and the comprehension of the underlying mechanisms appears crucial to understand their relationship with the pathology.

Using multiple genetic, pharmacological, imaging, and biochemical approaches, we demonstrate that, in different familial AD cell models, mitochondrial ATP synthesis is affected.

The defect depends on reduced mitochondrial pyruvate oxidation, due to both lower Ca 2 -mediated stimulation of the Krebs cycle and dampened mitochondrial pyruvate uptake.

Importantly, this latter event is linked to glycogen-synthase-kinase-3 (GSK-3) hyper-activation, leading, in turn, to impaired recruitment of hexokinase 1 (HK1) to mitochondria, destabilization of mitochondrial-pyruvate-carrier (MPC) complexes, and decreased MPC2 protein levels.

The defective mitochondrial bioenergetics influences glutamate-induced neuronal excitotoxicity, thus representing a possible target for future therapeutic interventions.
