Psoriatic Disease
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 Johnson & Johnson, 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.
Johnson & Johnson’s worldwide leadership in immunology has been established from a 30-year heritage of innovation and scientific breakthroughs. For over two decades, we have been a world leader in the development of biologic treatments that have modified the imbalance in patients’ immune systems and have transformed their lives.
We foster active collaborations with academia, emerging companies, patients, and patient groups to accelerate innovation and achieve our shared goals in tackling immune-mediated disease.

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).6
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
