TSRI study points way to potential therapies for hereditary spastic paraplegia

Scientists at The Scripps Research Institute have discovered that a gene mutation linked to hereditary spastic paraplegia, a disabling neurological disorder, interferes with the normal breakdown of triglyceride fat molecules in the brain. The TSRI researchers found large droplets of triglycerides within the neurons of mice modeling the disease.

Blocking bacteria's access to iron: an interview with Dr. Laxminarayana Devireddy

Iron is a key nutrient for nearly all living organisms, including bacteria. Iron is a cofactor for many enzymes necessary for basic metabolic reactions such as DNA synthesis and electron transport. Iron serves as the conduit for the electron transport chain that generates the energy necessary to drive the bacterial cell.
