This new study, not yet peer-reviewed or published in a journal, outlines
the effects of an infection on the peripheral immune system in the six
months after initial recovery. Blood samples were taken from each subject at
three points in the six-month study.
The researchers investigated levels of around 130 different immune cells, as
well as tracking antibody responses and measuring the expression of
thousands of different genes relating to immune functions. The findings
strikingly show persistent inflammatory responses and immune dysregulation
up to six months after recovery.
“The study found substantial dysregulation of immune cell numbers that was
strongest at 12-weeks post infection but was still evident in most cases for
up to six months and potentially even longer,” explains David Lynn, one of
the lead investigators on the project.
A number of genes linked to inflammation were found to be upregulated six
months after infection. This indicates these dysfunctional immune mechanisms
could be part of the long COVID mystery, however, Lynn is clear further
research is needed to verify this hypothesis. | i********r
