Increased expression in Th-POK^hd/hd Vα14i NKT cells of gene transcripts indicative of NKT17 cells. Bar graph displaying genes typical of NKT17 cells that were increased in RNA from 2 separate preparations of Th-POK^hd/hd liver Vα14i NKT cells, compared with Th-POK^hd/+ (experiment A) or Th-POK^+/+ (experiment B) age-matched controls. Plotted for each gene are the fold-change signal-intensity increases in the Th-POK^hd/hd samples compared with the control, calculated using Genespring software (Agilent). For genes that had multiple probes in the microarray, the arithmetic mean of the signal increases was plotted.
