Palo Alto, CA — Researchers at the Carnegie Institution for Science, with colleagues at the Nara Institute of Science and Technology, observed for the first time a fundamental process of cellular organization in living plant cells: the birth of microtubules by studying recruitment and activity of individual protein complexes that create the cellular protein network known as the microtubule cytoskeleton—the scaffolding that provides structure and ultimately form and shape to the cell. These fundamental results could be important to agricultural research and are published in the October 10, 2010, early on-line edition of Nature Cell Biology. (more…)

Research Shows a Promising New Method to Reduce Graft-Versus-Host-Disease After Bone Marrow Transplantation

ANN ARBOR, Mich.—University of Michigan researchers have discovered a new method to prevent the immune-system attacks that often occur following bone marrow transplants.

Bone marrow transplantation can cure patients with leukemia and other cancers even when the disease is resistant to other treatments. The success of this procedure relies on killing cancer cells by using immune cells from a bone marrow donor while avoiding an immune attack against the patient’s organs, which causes a dangerous complication called graft-versus-host disease.

ANN ARBOR, Mich.—Tuberculosis fights off the toxic agents, acidity and oxidants, that our immune system sends to destroy it, which is why the maddeningly drug-resistant bacterium can survive in harsh conditions in our bodies for essentially as long as its human host lives, new research shows.

COLLEGE PARK, Md. — A research team including University of Maryland chemistry and biochemistry Professor Lyle Isaacs and University of Massachusetts Amherst chemist Vincent Rotello has demonstrated that they can deliver a dormant toxin into a specific site such as a tumor for anti-cancer therapy, then chemically trigger the toxin to de-cloak and attack from within. It holds promise as a complex and sophisticated synthetic, therapeutic drug delivery system for living cells. (more…)
