TI - Novel Mouse Model of Murine Cytomegalovirus–Induced Adaptive NK Cells AID - 10.4049/immunohorizons.2100113 DP - 2022 Jan 01 TA - ImmunoHorizons PG - 8--15 VI - 6 IP - 1 4099 - http://www.immunohorizons.org/content/6/1/8.short 4100 - http://www.immunohorizons.org/content/6/1/8.full AB - NK cells are important mediators of viral control with the capacity to form adaptive immune features following infection. However, studies of infection-induced adaptive NK cells require adoptive cell transfer to lower the precursor frequency of “Ag-specific” NK cells, potentially limiting the diversity of the NK cell response. In seeking an unmanipulated model to probe the adaptive NK cells, we interrogated a wide range of Collaborative Cross (CC) inbred mice, inbred mouse strains that exhibit broad genetic diversity across strains. Our assessment identified and validated a putative “ideal” CC strain, CC006, which does not require manipulation to generate and maintain adaptive NK cells. Critically, CC006 mice, in contrast to C57BL/6 mice, are capable of developing enhanced NK cell–mediated protective responses to murine CMV infection following m157-mediated vaccination. This work both furthers our understanding of adaptive NK cells and demonstrates the utility of CC mice in the development and interrogation of immunologic models.
