Histones bound to lipid droplets inside cells offer protection against bacteria in flies, and possibly mice, thus suggesting a possible new innate immunity pathway.
The intestine contains distinct subregions specialized for digestion along its anterior-posterior axis, and the stem cells that constantly renew these subregions are not interchangeable.
Mice with a mutation that disrupts the release of growth hormone show greatly increased lifespan, which can be further increased by caloric restriction.
Reduced energy expenditure in obesity may result from reduced sensitivity to sympathetic activation due to inflammation-generated signals in adipose tissue.
A novel innate defense mechanism of cell lysis involves the coordinated oligomerization of a defensin by interaction with the membrane lipid, phosphatidylinositol 4,5-bisphosphate.

The RNA-binding protein MSI1, which is required for stem cell and cancer cell proliferation in the brain and epithelial tissues, also directly senses the concentration of long non-esterified omega-9 fatty acids.
