❦ Research led by The University of Queensland has found COVID-19 activates the same inflammatory response in the brain as Parkinson’s disease.

“We studied the effect of the virus on the brain’s immune cells, ‘microglia’ which are the key cells involved in the progression of brain diseases like Parkinson’s and Alzheimer’s,” Professor Woodruff said.

“Our team grew human microglia in the laboratory and infected the cells with SARS-CoV-2, the virus that causes COVID-19.

“We found the cells effectively became ‘angry’, activating the same pathway that Parkinson’s and Alzheimer’s proteins can activate in disease, the inflammasomes.”

Dr Albornoz Balmaceda said triggering the inflammasome pathway sparked a ‘fire’ in the brain, which begins a chronic and sustained process of killing off neurons.

“It’s kind of a silent killer, because you don’t see any outward symptoms for many years,” Dr Albornoz Balmaceda said.

“It may explain why some people who’ve had COVID-19 are more vulnerable to developing neurological symptoms similar to Parkinson’s disease.”

The researchers found the spike protein of the virus was enough to start the process and was further exacerbated when there were already proteins in the brain linked to Parkinson’s.

“So if someone is already pre-disposed to Parkinson’s, having COVID-19 could be like pouring more fuel on that ‘fire’ in the brain,” Professor Woodruff said.

“The same would apply for a predisposition for Alzheimer’s and other dementias that have been linked to inflammasomes.”
