OLR1 and COVID-19: Another study reported on the severity-related increase in immature CD16dim neutrophil subsets with increased levels of CD66b, LOX-1 and CD24 and overall changes in granulocyte populations, which are partly restored upon recovery from COVID-19, showing a near complete absence of immature CD16dim neutrophils and normalization of CXCR1, CXCR4 and CD147 levels [287].
