This finding was particularly apparent for IFN-γ–inducible chemokines CXCL9 (median 347 vs. 170 pg/mL; p = 0.02) and CXCL10 (median 4,139 vs. 143 pg/mL; p<0.001) which recruit CD4+ T cells, as well as B-cell chemoattractants CXCL12 (median 1,541 vs. 820 pg/mL; p<0.001) and CXCL13 (median 352 vs. 9 pg/mL; p<0.001) which recruit B cells to site of infection. Here, CXCL13 is linked to infection.
