Our pathbreaking research sheds
light on the role of TYK2 in psoriasis.

TYK2 pathway in psoriasis

Psoriasis is an immune-mediated disease characterized by the elevation of inflammatory cytokines regulated by several components. The tyrosine kinase 2 (TYK2) pathway plays a critical role in managing important inflammatory signals.1,2

For a deeper look at the TYK2 pathway, check out our video to see it in action.

The TYK2 pathway difference

The TYK2 pathway works within the immune system by regulating triggers of inflammation.1 The TYK2 pathway has not been shown to mediate signals involved in blood cell development and lipid metabolism.2-6
