How Can Stelara Help Psoriasis?

Stelara helps treat psoriasis by acting on the underlying cause: a misfiring autoimmune system.

Plaque psoriasis and psoriatic arthritis are both autoimmune disorders that affect the skin.

Both occur when the immune system inexplicably attacks cells in the upper layer of skin (epidermis).

Antibodiesactivate the immune response unnecessarily and release inflammatory substances, calledcytokines, into the bloodstream.

This leads to long-term inflammation that can be damaging to cells.

Stelara works by suppressing two specific cytokinesinterleukin 12 (IL-12) and interleukin 23 (IL-23).

Both play a key role in inflammatory diseases like psoriasis and psoriatic arthritis.
