Definitions for adult stem cells debated p.328

Adult tissues must maintain themselves and regenerate after damage. But are these crucial functions mediated by dedicated populations of stem cells, or do differentiated cells adopt stem-cell-like properties according to an organ’s needs? Here, two scientists present evidence from both sides of the debate.

Gut microbes alter the walking activity of fruit flies p.331

A gut bacterium has been found to modulate locomotor activity in the fruit fly Drosophila melanogaster. This effect is mediated by the level of a sugar and the activity of neurons that produce the molecule octopamine.

Increased synthesis of a coenzyme linked to longevity can combat disease p.332

The coenzyme NAD+ can be produced from the amino acid tryptophan. It emerges that inhibiting an enzyme that degrades an intermediate in this pathway can help to combat kidney and liver diseases in mouse models.

Combination treatment prevents HIV re-emergence in monkeys p.333

Antiviral drugs prevent HIV from replicating, but the virus can hide in the cells of infected individuals in a non-replicating, latent form. A two-pronged approach to target this latent virus shows promise in monkeys.
