Psoriatic Disease
The Immune System

The immune system is your body’s defence against disease and pathogens.[1] In immune-mediated inflammatory diseases, the immune system wrongly attacks its own tissues and causes inflammation, pain, and can result in loss of function.[2][3]

At Janssen, we are focusing our scientific expertise on creating ways to restore the body’s immune balance. We’re committed to discovering new medicines that will redefine the way we maintain immune-mediated health.

Psoriasis (Pso)

Psoriasis is an immune system-related skin disorder.[4] It can manifest in a few different ways and can appear anywhere on your body, often in itchy, sometimes painful, red patches or silvery scales.[5] It can also cause thick, pitted or ridged nails.[5] Approximately 30% of people who have Pso later develop PsA (see below).[4]

Psoriatic Arthritis (PsA)

Psoriatic arthritis (PsA) is a chronic, immune-mediated inflammatory disease that affects the joints.[6] It is a form of arthritis that affects some people who have psoriasis,[7] though some people never develop psoriasis, or develop PsA first.[6] The most common symptoms of PsA are pain, stiffness and swelling in your joints.[7]
