Due to a production error, reference 5 was incorrectly written as “Shissler SC, Webb TJ. The ins and outs of type I iNKT cell development. Mol Immunol. (2019) 105:116–30. doi: 10.1016/j.molimm.2018.09.023.” It should be “Shissler SC, Lee MS, Webb TJ. Mixed signals: co-stimulation in invariant natural killer T cell-mediated cancer immunotherapy. Front Immunol. (2017) 8:1447. doi: 10.3389/fimmu.2017.01447”.
The publisher apologizes for this mistake. The original article has been updated.
