Given the significance of iNKT cells for immune response initiation and regulation, these results may also help in understanding the increased incidence of both infections and malignancies, as well as the increased severity of autoimmune conditions, in the elderly 76, As occurs with conventional T-cells, NKT cells develop from thymic precursors. ILresponsive innate lymphoid cells are increased in inflammatory bowel disease.

The development of these cells is mediated by the GATA3 transcription factor Both innate and adaptive immune responses represent an integral system of host defense.
