A different view [1]: > In the new study, Belgian and German researchers claim that the virus infects sustentacular cells but not OSNs [olfactory sensory neurons]. “That is just a critical distinction,” said the senior author Peter Mombaerts, who directs the Max Planck Research Unit for Neurogenetics in Frankfurt, Germany. “Once you believe that olfactory neurons can be infected, there is a quick route into the olfactory bulb and then you’re in the brain already.” > Nobody doubts that the central nervous system is affected by the disease; the debate concerns whether these effects are due to the virus infecting neurons or some more indirect mechanism, such as an inflammatory response in the blood irrigating the brain – with different implications for prognosis and treatment.
