Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection causes severe coronavirus disease 2019 (COVID-19) in a small proportion of infected individuals. The immune system plays an important role in the defense against SARS-CoV-2, but our understanding of the cellular immune parameters that contribute to severe COVID-19 disease is incomplete. Here, we show that populations of effector gammadelta T cells are associated with COVID-19 in unvaccinated patients with acute disease. We found that circulating CD27(neg) CD45RA(+) CX3CR1(+) Vdelta1(effector) cells expressing Granzymes (Gzms) were enriched in COVID-19 patients with acute disease. Moreover, higher frequencies of GzmB(+) Vdelta2(+) T cells were observed in acute COVID-19 patients. SARS-CoV-2 infection did not alter the gammadelta T cell receptor repertoire of either Vdelta1(+) or Vdelta2(+) subsets. Our work demonstrates an association between effector populations of gammadelta T cells and acute COVID-19 in unvaccinated individuals.
