Notably, differences between HC and CF were less obvious when some ‘key’ myeloid cytokines (IL-1b, TNF, IL-6, IL-8, IL-10) were considered (panels E-I), except for a low expression of IL-10 in CF cells, which was nevertheless inducible by the PMA/iono mix. The gene discussed is IL1B; the disease is cystic fibrosis.
