WebNov 9, 2024 · CCL14 is a ligand of CCR1 [ 16, 17 ], CCR5 [ 17, 18 ], and a weak agonist of CCR3 [ 17 ]. For this reason, it serves as a chemotactic agent for monocytes but not for T lymphocytes, neutrophils, and eosinophils [ 15 ], although a later study showed that CCL14 may be a neutrophil chemoattractant [ 19 ]. CCL14 is secreted as an inactive proform. WebCCR4 and CCR8 are expressed on a subset of human peripheral blood CD4 + CD25 + CTLA4 + T cells, which are associated with suppression of T-cell responses and may be important in the generation of tolerance. 23 Mature DCs attract these cells in vitro by secreting CCR4 ligands CCL17 and CCL22. In addition, inflamed peripheral tissues may …
