Choroidal Regulations Involved in the Cerebral Fluid Response to Altered Gravity: Water Transports and Serotonergic Receptors

The process of adapting to microgravity is well known to change the distribution of fluids in the body, including the brain, kidneys, and lungs. In all of these organs, a family of proteins called aquaporins transport water. This study was designed to investigate the effect of space flight on aquaporins.

It was planned that immediately postflight, the brains, pituitary glands, kidneys, and lungs of eight mature, male rats would be removed, processed, and analyzed using conventional electron microscopy and immunocytochemistry detection.

The payload was not recovered.
