Psoriasis is an inflammatory skin disorder. The inflammatory process involves the recruitment and activation of inflammatory cells. Non-contagious condition – transmitted genetically Non-contagious condition – transmitted genetically Lifelong disease characterised by recurrent exacerbations Lifelong disease characterised by recurrent exacerbationsAetiology: T-cells are activated, to the extent that they trigger other immune responses, which lead to release of cytokines that promote inflammation and rapid turnover of skin cells T-cells are activated, to the extent that they trigger other immune responses, which lead to release of cytokines that promote inflammation and rapid turnover of skin cells

3. What is Psoriasis(cont). The role of the thymus derived lymphocyte (T- cell) in the expression of psoriatic plaques has made it and its action a target for new therapies.

5. Who gets Psoriasis (cont). Studies have proven there is a genetic link. Studies have proven there is a genetic link. There is a positive family history in one third of sufferers. Less likely in late onset psoriasis. There is a positive family history in one third of sufferers. Less likely in late onset psoriasis. If one parent has psoriasis there is a 10 – 25% risk to the child. If both parents are affected the risk increases from 50 – 60%. If one parent has psoriasis there is a 10 – 25% risk to the child. If both parents are affected the risk increases from 50 – 60%. Investigators are using molecular genetics technology to try and unravel the genes that causes psoriasis.
