Dendritic cell (DC) activation is essential for the induction of immune defense against pathogens, yet needs to be tightly controlled to avoid chronic inflammation and exaggerated immune responses. Here, we identify a mechanism of immune homeostasis by which adaptive immunity, once triggered, tempers DC activation and prevents overreactive immune responses. T cells, once activated, produce Protein S (Pros1) that signals through the TAM receptor tyrosine kinases in DCs to limit the magnitude of DC activation. Genetic ablation of Pros1 in mouse T cells leads to increased expression of co-stimulatory molecules and cytokines in DCs, enhanced immune responses to T cell-dependent antigens, as well as increased colitis. Additionally, PROS1 is expressed in activated human T cells and its ability to regulate DC activation is conserved. Our results identify a heretofore unrecognized, homeostatic negative feedback mechanism at the interface of adaptive and innate immunity that maintains the physiological magnitude of the immune response.
