- The following are steps in the cell-mediated inflammatory response. Put them in the correct order. 1. Activated macrophage cells release cytokines. 2. Antigen is engulfed and presented by a macrophage cell w/MHC II complex. 3. The TH1 cell's CD4 protein binds to the MHC II complex. 4. Phagocytosis and inflammation occur. 5. Th1 secrete TNF-alpha and other cytokines which activates the macrophage.
