Emotion-regulating protein lacking in panic disorder
...nin receptor is reduced by nearly a third in three structures
straddling the center of the brain. The finding is the first in living humans to show that the receptor, which is pivotal to the action of widely prescribed anti-anxiety medications, may be abnormal in the disorder, and may help to explain how genes ...

...ss the outer membrane of cells, but they do affect structures
within cells. One of the main effects seems to be calcium release from a cellular structure called the endoplasmic reticulum. "In a nanosecond, we cause this major physiological event in the cell," says Vernier. "It's completely indirect and remote,...

A new hypothesis about Alzheimer's disease
...ases are caused by the misfolding of proteins into structures
that lead them to cluster together, forming microscopic fibril or plaques, which deposit in internal organs and interfere with normal function, sometimes lethally. In the case of Alzheimer's, these fibrils kill nerve cells in areas of the brain that ...
