# Researchers Find Dopamine Deficit Causes Breathing Issues in Rett Syndrome

UConn researchers link Rett syndrome breathing instability to dopamine loss in the carotid body.

University of Connecticut researchers reported in Current Biology that abnormal breathing episodes in Rett syndrome are caused by a dopamine deficit in the carotid body. [^1]

In 2026, the Connecticut Department of Agriculture issued a reminder to horse and livestock owners to take preventive measures against mosquito-borne diseases, including West Nile virus (WNV) and eastern equine encephalitis (EEE). [^2]

Dan Mulkey, a neurophysiologist at UConn, stated that the loss of dopamine inhibition in the carotid body means the breathing system is 'driving without brakes'. [^3]

Monica Strain, a neurophysiologist at Boston Children's Hospital, led the research using a mouse model lacking the MECP2 gene to study breathing patterns. [^4]

Treatment with pramipexole, a drug typically used to treat Parkinson's disease, helped normalize breathing in MECP2-deficient mice. [^5]

The Connecticut Agricultural Experiment Station reported in 2026 that it had detected an increase in West Nile virus-infected mosquitoes in recent weeks. [^6]
