CCL17 and malaria: Malaria-associated chemokines (CCL17 [C-C motif chemokine ligand 17], CCL22) exacerbate this suppression by promoting regulatory dendritic cell phenotypes that inhibit effector T-cell priming and the recruitment of immunosuppressive cells, while elevated CXCL11 (C-X-C motif chemokine ligand 11) and CCL28 correlate with impaired vaccine efficacy and adverse clinical outcomes in endemic populations [148,169,170,171,172,173].
