We thank the N.D.H. laboratory members A. Doan and T. Camilleri for technical assistance and animal husbandry. We extend our gratitude to Monash University platform staff and administration for their services. We are extremely grateful to M. Busslinger (IMP, Austria) for providing the Ikzf1 mice, E. Vivier (CIML, France) for providing the Ncr1 mice, M. Caligiuri (City of Hope, USA) for providing the Il15Tg and F. Ishikawa (RIKEN, Japan) for providing the human IL-15/IL-7 transgenic NSG mice and D. Lee (Nationwide Children’s Hospital, USA) for the K562-CSTX002 cell line. W.G. was supported by a Melbourne International Research Scholarship. M.F. was supported by an Investigator Fellowship from the Prostate Cancer Foundation (USA).

N2 - Ikaros transcription factors are essential for adaptive lymphocyte function, yet their role in innate lymphopoiesis is unknown. Using conditional genetic inactivation, we show that Ikzf1/Ikaros is essential for normal natural killer (NK) cell lymphopoiesis and IKZF1 directly represses Cish, a negative regulator of interleukin-15 receptor resulting in impaired interleukin-15 receptor signaling. Both Bcl2l11 and BIM levels, and intrinsic apoptosis were increased in Ikzf1-null NK cells, which in part accounts for NK lymphopenia as both were restored to normal levels when Ikzf1 and Bcl2l11 were co-deleted. Ikzf1-null NK cells presented extensive transcriptional alterations with reduced AP-1 transcriptional complex expression and increased expression of Ikzf2/Helios and Ikzf3/Aiolos. IKZF1 and IKZF3 directly bound AP-1 family members and deletion of both Ikzf1 and Ikzf3 in NK cells resulted in further reductions in Jun/Fos expression and complete loss of peripheral NK cells. Collectively, we show that Ikaros family members are important regulators of apoptosis, cytokine responsiveness and AP-1 transcriptional activity.
