The first survey of the complete morphologies of nerve endings in the skin of mice has revealed enormous structural diversity.

A protein complex that enables cells to transport substances across their membranes, and that typically consists of four subunits, can also function as two hemicomplexes, each with two subunits.

A cellular motor protein helps to ensure that microtubules are oriented correctly within neuronal dendrites

The Notch signaling pathway has a central role in the formation of the circuit that controls egg-laying in the nematode worm C. elegans.

Sensory neurons in the olfactory system develop from two different regions of the ectoderm, the olfactory placode and the cranial neural crest, whereas sensory neurons within the eye and ear develop from just one region.

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.

A combination of detailed sampling and mathematical modeling suggests that the response of immune cells to reactivation of herpes simplex virus 2 is extremely rapid and effective within microscopic areas of genital skin.

The receptor EBI2 is essential for correctly positioning CD4+ dendritic cells in the spleen so that they can present blood-borne antigens to T cells and thereby provoke an antibody response.
