IL-7 enables γδ T cells to fully differentiate into γδT17 cells34 that coproduce IL-17F along with IL-17A, and rapidly migrate into inflamed tissues in response to CCR2 and CCR5 ligands such as CCL2 and CCL8.37, 38 As shown for murine γδT17 cells, human Vδ2+ T cells that co-express CCR2 and CCR5 also express the IL-7 receptor and show a Th17-like phenotype (CCR6+CD161+IL-23R+).39 Transcriptional analyses of respiratory cell populations in response to SARS-CoV-2 infection reveal strong upregulation of CCL8, CCL2, CXCL9, CXCL10 and their respective receptors,11, 15, 27 and global upregulation of IL-17 and IL-17F-related pathways,26 including the CCR6 ligand CCL20 and IL-23.27
