NIEHS researchers have found that in rats, exposure to low levels of the chemical GenX may affect the function of certain protective proteins at the blood-brain barrier. This discovery is important because it suggests that GenX — part of the per- and polyfluoroalkyl substances (PFAS) chemical family — can alter how the body safeguards sensitive organs against exposures.
