ABSTRACT
We identified IL-17A-positive neutrophils in Wolbachia-positive Onchocerca volvulus nodules using an antibody that has previously reported IL-17A-positive neutrophils in several inflammatory conditions. However, we could not detect IL-17A using a range of alternative assays. Our data question the IL-17A antibody specificity and the ability of human neutrophils to express IL-17A.
