Dermatology Drug for plaque psoriasis

Plaque Psoriasisthat the disease may result from a disorder in

the immune system. The immune system makes white blood cells that protect the body from infection. In psoriasis, the T cells (a type of white blood cell) abnormally trigger inflammation in the skin. These T cells also cause skin cells to grow faster than normal and to pile up in raised patches on the outer surface of the skin.

FACTOR TRIGGER PSORIASISThose with a family history of psoriasis have

an increased chance of having the disease. Some people carry genes that make them more likely to develop psoriasis. Certain factors may trigger psoriasis, such as injury to the skin, sunlight, stress, alcohol, HIV infection, smoking, and certain drugs

SIGINS AND SYMPTOMSAn individual with plaque psoriasis usually

has patches of red, raised, scaly areas on the skin that may itch or burn. The patches are usually

found on the knees, elbows, trunk, or scalp
