The Brief
- A study by Mali et al. reports that coronaviruses, including SARS-CoV-2, trigger sneezing, coughing and pain hypersensitivity by directly activating nociceptors.
- The viral protein PLpro alone is sufficient to produce these effects.
- The work identifies a mechanism by which the virus drives hallmark symptoms.
Why it matters
It identifies a direct neural route by which a coronavirus protein produces sneezing, coughing and pain, which can help explain these symptoms and point to possible targets for treatment.
Who’s affected
- virologists and immunologists studying coronaviruses
- neuroscientists studying sensory neurons and pain
