By using immune cells called dendritic cells to deliver drugs, it is possible to target and kill specific members of another class of immune cell, known as T cells, and to prevent these cells from attacking the body's own tissues in cases of autoimmune disease.

Sugar levels in leaves act as a signal for plants to switch from their juvenile to their adult form by regulating the expression of two genes.

Exposing rats to acute stress increased the generation of new neurons in a subregion of the hippocampus, and improved the animals' performance in a memory task two weeks later.

The eye produces a protein that inhibits the growth of blood vessels in the deep retina, which includes the photoreceptor layer, and disruption of this process can lead to blindness.

The Botryllus schlosseri genome yields insights into the evolution of hematopoiesis.

Cells that give rise to the infectious form of parasitic flatworms called schistosomes show similar patterns of gene expression to stem cells in free-living flatworms.

Proteins implicated in Alzheimer’s disease, including amyloid precursor protein and ApoE receptors, interact with each other and with a signalling molecule called agrin to influence the development of the neuromuscular junction.

Skin cells from a patient with retinitis pigmentosa have been used to generate induced pluripotent stem cells, which could potentially form the basis of new treatments for this disease.

Computational modelling indicates that C₄ photosynthesis in distantly related plant species arose through a number of independent evolutionary paths.

The sequencing of microbial genomes reveals that the presence of a particular microbial species in the gut may increase the risk of the autoimmune disease rheumatoid arthritis.
