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.23
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.
