Scientists at the Johns Hopkins Kimmel Cancer Center have found that a gene pathway linked to a deadly form of leukemia may provide a new way to treat autoimmune diseases, including multiple sclerosis. Their tests in cell cultures and mice suggest that blocking the pathway by interfering with a blood cell growth gene, known as FLT3, targets an immune system cell often ignored in favor of T-cell targets in standard therapies.

Canadian scientists have developed some clever molecular trickery that is helping to reduce the drug cravings of addicted rats. One of the problems in addiction is that neurons in some parts of the brain lose glutamate receptors from the cell surface, and those receptors are important for communication between neurons. The researchers have sidestepped this problem by crafting a peptide that mimics a portion of the tail of the glutamate receptor and, once inside a neuron, serves as a decoy to prevent the loss of glutamate receptors.

Using a tiny flatworm best known for its extraordinary ability to regenerate lost tissue, researchers have identified a gene that controls the ability of stem cells to differentiate into specialized cells. The gene encodes a protein that is most similar to the protein PIWI, an important regulator of stem cells in organisms ranging from plants to humans.

Species evolve at very different rates, and the evolutionary line that produced humans seems to be among the slowest. The result, according to a new study by scientists at the European Molecular Biology Laboratory (EMBL), is that our species has retained characteristics of a very ancient ancestor that have been lost in more quickly-evolving animals. This overturns a commonly-held view of the nature of genes in the first animals. The work appears in the current issue of the journal Science.

The development of effective vaccines for people with compromised immune systems may be feasible after all, according to a team of researchers, who demonstrated their approach could protect against pneumocystis pneumonia in mice lacking the same population of immune cells that HIV destroys in humans. The vaccine platform developed by Children's Hospital of Pittsburgh researchers, working in collaboration with researchers from the University of Pittsburgh and Louisiana State University, suggests that the immune system can be primed to ward off other infections as well, such as those caused by the flu, smallpox or exposure to anthrax, even in patients who have the highest risk for infection.

Looks can be deceiving. New gene study redraws family tree of lizards and puts primitive-looking iguanas (shown here) and relatives at the top instead of bottom of the tree." Credit line: Copyright Eladio Fernandez 2005.The most comprehensive analysis ever performed of the genetic relationships among all the major groups of snakes, lizards, and other scaly reptiles has resulted in a radical reorganization of the family tree of these animals, requiring new names for many of the tree's new branches. The research, reported in the current issue of the journal C. R. Biologies, was performed by two biologists working at Penn State University: S. Blair Hedges, professor of biology, and Nicolas Vidal, a postdoctoral fellow in Hedges' research group at the time of the research who now is a curator at the National Museum in Paris.

In the neural train wreck that is stroke, the cutoff of oxygen kills brain cells through a buildup of acid, as well as by overexciting receptors on the surface of brain cells. Now, researchers exploring the detailed mechanism of this excitotoxicity and acidotoxicity have discovered how an insidious chain of molecular events contributes to its damage. In an article in the November 23, 2005, issue of Neuron, Jun Gao and colleagues say that their findings could contribute to the development of drugs to protect against the molecular "cabal" that produces such lethality.
