Immunology Research


We have a strong history of delivering biological medicines for immunological diseases and we continue to build a pipeline of exciting, new biotechnological products, while expanding into small-molecule oral medications and broadening our disease focus in autoimmune, inflammatory and pulmonary diseases. Through our ongoing efforts in discovery, biomarkers, clinical research and external innovation, we are poised for continued leadership and growth, bringing transformational medicines to patients and healthcare providers around the world.

Janssen has produced a comprehensive source of information on psoriasis  for patients called Psoriasis 360, including treatment options and practical advice to help patients reduce the physical, social and emotional impact that a long-term skin condition can have on their lives.

Psoriasis  is estimated to affect more than 73,000 people in Ireland. Anyone can develop psoriasis. It is equally common in men and women.[1]

More than Skin Deep – Psoriatic Arthritis Awareness Campaign

Janssen Ireland, supported by Arthritis Ireland, has launched the More than Skin Deep campaign to educate people about the link between psoriasis and psoriatic arthritis – an inflammatory form of arthritis that can cause pain, swelling and damage to joints.

Our research revealed that 46%[2] of people with psoriasis have never heard of psoriatic arthritis. Yet, up to 30%[3] of the estimated 73,000[4] people with psoriasis in Ireland may go on to develop the condition.

These videos – presented by Paul Walsh from RTE’s Doctors on Call – provide information from experts on psoriatic arthritis including the signs and symptoms and how it can be managed.

More than Skin Deep: Interview with Marion Morrissey, who has psoriatic arthritis, about her journey from psoriasis to psoriatic arthritis and how she manages her condition.

The Journey: Consultant Rheumatologist, Professor David Kane and Consultant Dermatologist, Dr Anne-Marie Tobin, both based in Tallaght Hospital, Dublin, talk about the link between psoriasis and psoriatic arthritis, including the signs, symptoms and how it is diagnosed.

Managing the Journey:  Professor David Kane and Dr Anne-Marie Tobin give advice on how best to manage the journey from psoriasis to psoriatic arthritis.

What is psoriatic arthritis?

Psoriatic Arthritis (PsA) is an autoimmune disease - a form of inflammatory arthritis that can cause pain, swelling and damage to any joint in the body.[5] In most cases people with PsA develop the condition following the onset of psoriasis. This does not mean that all people with psoriasis will develop PsA. Due to the similarities of symptoms it may sometimes be confused with other forms of arthritis.[5]

The symptoms of psoriatic arthritis vary from person-to-person but the main indicators include:4

  • Thickening, discoloration and pitting of the nails
  • Stiff, painful, swollen joints. Psoriatic arthritis typically affects the ankle, knees, toes and lower back
  • Sausage-like swelling of the fingers or toes
  • Tenderness or pain where tendons or ligaments attach to bones. This commonly occurs at the heel or the bottom of the foot, but it can also occur in the elbow
  • Pain and swelling at the back of the heel
  • Eye inflammation (less frequent)
