Postdoc genetics and biochemistry leading to cellular stress in long COVID

Postdoc genetics and biochemistry leading to cellular stress in long COVID

Published Deadline Location
12 Nov 25 Nov Amsterdam
Do you want to make the difference together with us; searching for the cause of long-COVID? Long-COVID affects tens of thousands of people in the Netherlands alone, who can no longer live the life they want.

Job description

As a postdoc researcher you will study long-COVID. Our earlier studies showed the expression and activity of the enzyme IDO2 in blood and brain tissue from patients with long-COVID. Check out our earlier study about post-acute sequela of SARS CoV2 infection here: PMID 37506544. The resulting kynurenine products in long-COVID relate to cellular metabolic stress reflected by autophagy and mitochondrial dysfunctioning, and provide an explanation for the prolonged expression of IDO2 in long-COVID patients. Others have shown that the kynurenine metabolites correlate with cognitive symptoms, postexertional malaise and inflammation.

A better understanding of the regulation of IDO2 expression and activity can lead to the identification of diagnostic markers for long-COVID. This can explain why a SARS CoV2 infection leads to post-COVID in some individuals only.

Continuing on what we know now, we will analyse IDO2 activity and specific genetic factors for IDO2 expression in long-COVID further. We have indications that this research is also relevant to children with post-COVID and patients with ME/CVS.

In this project we will use biobanked material from long COVID patients, in particular plasma, blood cells (PBMC) and brain tissue.
  • With PBMC we aim to delineate the catalytic pathway of IDO2 further in more detail using stable isotope substrates and UPLC tandem mass spectrometry. After validation of the analytical procedures, we will screen a large set of plasma samples aimed at identifying a diagnostic marker for long COVID and possibly other post-acute infectious syndromes.
  • In parallel, we aim to clarify why some cells do not express IDO2 and neighbouring cells do express IDO2, by comparative transcriptomics and metabolomics. This will be done in both brain tissue, by dissecting specific areas using a laser, as well as blood cells.
  • Moreover, using similar approaches in combination with analysing genetic polymorphisms, we try to establish why some individuals express IDO2, and develop long COVID, whereas others do not express IDO2 and not develop long COVID. As a follow-up we expect to use precision cut brain slices to evaluate findings.
