CCL3 and Thrombocytopenia: Interestingly, a negative correlation was observed between levels of CCL20 (MIP-3A), CCL17 (TARC), CXCL2 (GROB), and CXCL8 (IL-8) and active hematologic system involvement (mostly thrombocytopenia) (Table 2), and several additional chemokines (CXCL13 [BLC], CCL3 [MIP-1α], and CXCL11 [I-TAC]) trended towards significance.
