Phosphorylation of c - Src , which was shown to be activated by AhR ligands , was also increased by I3S and TCDD , and blocking of c - Src activity by 4 - amino - 5 - ( 4 - chlorophenyl ) - 7 - ( t - butyl ) pyrazolo [ 3 , 4 - d ] pyrimidine ( PP2 ) inhibited phosphorylation of both c - Src and STAT3 , raising a possibility that stimulatory activities of I3S and TCDD on Th17 differentiation could be exerted via increased phosphorylation of c - Src , which in turn stimulates STAT3 activation .
