The pick of the nibbled bits
Article Abstract:
The specialized phagocytes called dendritic cells in the immune system recycle the molecular fragments from ingested proteins, transporting the scraps to their plasma membranes for display on their external surface as antigens. The voracious appetites of phagocytes suggest a dilemma concerning mixed meals, phagocytosis of two particles, one that can trigger an immune response and another that cannot, could launch a misguided response against benign molecules.

Reactive oxygen species produced by NADPH oxidase regulate plant cell growth
Article Abstract:
It is shown that reactive oxygen species (ROS) accumulate in growing wild-type root hairs but their levels are markedly decreased in Arabidopsis thaliana rhd2 mutants. It is indicated that NADPH oxidases control development by making ROS that regulate plant cell expansion through the activation of Ca(super 2+) channels.

The voltage dependence of NADPH oxidase reveals why phagocytes need proton channels
Article Abstract:
For the first time, the complete current-voltage relationship of NADPH oxidases in phagocytes is identified and measured. The article outlines its importance to the immune system's resistance to microbial infection.
