Researchers describe how PDNF protein prolongs the life of T. cruzi parasite

The parasite Trypanosoma cruzi (or T. cruzi), which causes Chagas' disease, will go to great lengths to evade death once it has infected human host cells, researchers have discovered. In a study published in the November 17 online issue of Science Signaling, the researchers describe how a protein called parasite-derived neurotrophic factor (PDNF) prolongs the life of the T. cruzi parasite by activating anti-apoptotic (or anti-cell-death) molecules in the host cell. These protective mechanisms help to explain how host cells continue to survive despite being exploited by T. cruzi parasites.

New step in the proofreading process that helps maintain accuracy of DNA replication identified

Wayne State researchers have for the first time observed the movement of a single molecule of DNA polymerase as it incorporates nucleotides one by one. More significantly, they have identified a previously unknown step that they speculate is part of the proofreading process known to prevent the polymerase from producing cancer-causing mutations.

Study suggests brain can integrate new information without jeopardizing established memories

Our ability to learn new information and adapt to changes in our daily environment, as well as to retain lifelong memories, appears to lie in the minute junctions where nerve cells communicate, according to a new study by NYU Langone Medicine Center researchers. The study is published online this week in the journal Nature.

Study explores brain's rewiring processes during motor learning

New connections begin to form between brain cells almost immediately as animals learn a new task, according to a study published this week in Nature. Led by researchers at the University of California, Santa Cruz, the study involved detailed observations of the rewiring processes that take place in the brain during motor learning.

B cells and their antibodies defend against microbes and control commensal microflora

Microbes populated the earth long before any eukariotic cell. Therefore, in order to survive, mono and multi-cellular organisms had to develop mechanisms of adaptation, cohabitation and defense against bacteria, fungi and viruses. One of these mechanisms is mediated by immunoglobulins in the serum and at mucosal surfaces.

Studies examine interaction of ribosome with molecular partners

Two new studies reveal in unprecedented detail how the ribosome interacts with other molecules to assemble new proteins and guide them toward their destination in biological cells. The studies used molecular dynamics flexible fitting (MDFF) to examine the interaction of the ribosome with two prominent molecular partners.

Mutated IDH1 gene has novel enzyme activity consistent with cancer-causing gene: Study

Agios Pharmaceuticals today announced that its scientists have established, for the first time, that the mutated IDH1 gene has a novel enzyme activity consistent with a cancer-causing gene, or oncogene. This breakthrough discovery shows that the mutated form of IDH1 produces a metabolite, 2-hydroxyglutarate (2HG), which may contribute to the formation and malignant progression of gliomas, the most common type of brain cancers.

Image of a water flea wins top prize in the 2009 Olympus BioScapes Digital Imaging Competition

A glowing, eerily beautiful image of a water flea with its radiant green "crown of thorns" took top prize in the 2009 Olympus BioScapes Digital Imaging Competition®, the world's foremost forum for showcasing microscope photos and movies of life science subjects. Dr. Jan Michels, a zoologist at the University of Albrecht, Kiel, Germany, took top honors for the image of a water flea, with its defensive "crown of thorns" to protect it against predators. The image reveals not only the exoskeleton, but also interior detail down to the nuclei within its cells, seen as tiny, glowing blue dots. This
