We further checked if rZmp1 treatment of THP-1 cells resulted in release of chemotactic chemokines, such as MCP-1, MIP-1β and IL-8 that are known to recruit monocytes, neutrophils, memory T cells, and dendritic cells to the sites of infection (Taub et al., 1995; Gerszten et al., 1999; Bystry et al., 2001; Deshmane et al., 2009). Here, CCL2 is linked to infection.
