IFN-γ, MIP-1β (a chemoattractant for macrophages and NK cells), RANTES (a chemokine for T-cells), and MIG (a T-cell attractant and activator) were increased one day following subcutaneous infection relative to aerosol or intranasal infection, followed by a return to baseline one day later when the same cyto/chemokines become increased in aerosol or intranasal infection. The gene discussed is CXCL9; the disease is infection.
