1. Drug helps, doesn’t hurt, lung disease » Respiratory distress syndrome patients treated with a neuromuscular blocker are more likely than those on a placebo to survive 90 days, and show no increase in muscle weakness—a common concern among doctors.

2. Skip the surgery? » A nonsurgical treatment for severe aortic stenosis, a type of heart disease characterized by the narrowing of the aortic valve opening, may provide an alternative for patients who are not candidates for open-heart surgery. The treatment replaces the aortic valve through a catheter.

3. How T regs limit inflammation »T regulatory cells can multiply their numbers by secreting the cytokine interleukin IL-35, which converts the population of killer T cells into regulatory cells that suppress inflammation, providing a new explanation for how inflammation is reeled in after an infection is cleared.

4. Natural helpers fight infection » A novel population of innate immune cells, identified in the gut adipose tissue of humans and mice and nicknamed “natural helper cells,” produce large amounts of cytokines and may play an important role in fighting off parasites.
K. Moro et al., Nature, 463:540-44, 2010. Evaluated by A. Bhandoola, Univ Penn; J.G. Foster & S. Ward, Univ Bath; T. Randall, Univ Rochester; D. Umetsu, Child Hosp Boston; D. Seshasayee & F. Martin, Genentech; J. Di Santo, Institut Pasteur; R. Locksley, UCSF. Free F1000 Evaluation
5. Cells sticking together » In response to tension from adjacent cells, alpha-catenin, a cell adhesion protein, recruits actin binding proteins to strengthen cell-to-cell junctions, rapidly reacting to rearrangements in the local environment.

6. Silent effects »Mutations in exons that do not change protein sequences can still have dramatic effects on gene expression in E. coli. Surprisingly, these effects are caused by changes in mRNA stability, not by codon bias.
G. Kudla et al., Science, 324:255-58, 2009. Evaluated by P. Benos, Univ Pittsburgh; D. Dykhuizen, Stony Brook; J. Bahler, UCL; N. Dhar & J. McKinney, EPFL; A. Gasch, Univ Wisc–Madison. Free F1000 Evaluation
7. Rat dad’s diet affects pups »Male rats fed a high-fat diet had daughters with diabetes-like beta-cell dysfunction, showing, for the first time in mammals, that environment of the father can influence the phenotype of the offspring.
