CXCL1 and infection: H37Rv infection‐triggered increased inflammatory immune response is also confirmed based on the increased gene expression profiles of chemokines such as CXCL1, CXCL2, CXCL3, CXCL8, CCL3 and CXCL4 which help in the recruitment of poly‐morpho‐nuclear cells such as neutrophils during tissue inflammation.
