Function Cytokine with immunoregulatory activity. May promote the transition between innate and adaptive immunity. Induces the production of IgG(1) and IgG(3) in B-cells (By similarity). May play a role in proliferation and maturation of natural killer (NK) cells in synergy with IL15. May regulate proliferation of mature B- and T-cells in response to activating stimuli. In synergy with IL15 and IL18 stimulates interferon gamma production in T-cells and NK cells. During T-cell mediated immune response may inhibit dendritic cells (DC) activation and maturation.
Involvement in disease Immunodeficiency, common variable, 11 (CVID11)
Subcellular Location Secreted
Protein Families IL-15/IL-21 family
Tissue Specificity Expressed in activated CD4-positive T-cells but not in CD8-positive T-cells, B-cells, or monocytes.
