Direct relationships
TH1 macrophage activation
IFN-gamma reinforces TH1 polarization and macrophage-activating context
Cytotoxic T cells produce IFN-gamma during antiviral and tumor responses
IFN-gamma anchors TH1, cytotoxic, macrophage-activating antiviral and intracellular pathogen programs
NK cells are early IFN-gamma producers during viral and tumor surveillance responses
Cytokine ecology
Signal Role
IFN-gamma coordinates TH1 and cytotoxic immunity, increasing antigen presentation and macrophage antimicrobial programs.
Pathway
Source Cells
Target Cells
Inflammatory Role
Raises antigen presentation, macrophage killing, chemokine production, and cytotoxic immune tone.
Regulatory Role
Supports pathogen containment and anti-tumor surveillance.
