(EMAILWIRE.COM, April 19, 2012 ) New York, NY -- Experts are not sure what the exact cause of psoriasis is. All we know that the immune system plays a part besides the excessive growth and reproduction of skin cells.
Fault of the epidermis
One hypothesis is that psoriasis is mainly a fault of the epidermis (the upper or outer layer of skin) and its keratinocytes. The keratinocyte is the major constituent of the epidermis, making up 95% of the cells found there. Keratinocytes are cells found in the epidermis - those at the outer surface of the epidermis are dead and form a tough protective layer, while the cells below divide and replenish the supply.
An immune-mediated disorder
Another hypothesis is that the excessive reproduction of skin cells is secondary, and that the main factor is related to an immune system disorder.
Our immune system is designed to protect us from foreign bodies and pathogens (things that cause disease), such as bacteria, viruses, and toxic substances. An autoimmune reaction occurs when the immune system mistakes a normal or good substance for a pathogen, and attacks it. Sometimes our immune system may attack good tissues and cells in our bodies; this is called an autoimmune disease.
Our T-cells (T lymphocytes) normally help protect the body against infection - they are a type of white blood cell and form part of our immune system. T cells travel throughout the human body to detect and fight off foreign substances, such as bacteria or viruses. If a person has psoriasis, however, the T cells attack healthy skin cells by mistake. Experts believe these T-cells become active, migrate to the dermis (inner/deeper layer of skin) and trigger the release of cytokines as well as inflammation.
Experts do not know what triggers the activation of T-cells - genetic and environmental factors are most likely, they say. The result is a cycle of skin cell production becoming faster and faster. It normally takes 28 days for skin cells to be created and then to die - this cycle is reduced to 2 to 6 days in patients with psoriasis, causing dead skin cells to accumulate on the surface of the skin, in thick scaly patches.
Why is skin care important?
Skin care is important because it can prevent or reduce the symptoms of psoriasis. It can also help prevent infections and injuries to skin, which can result in flare-ups of symptoms. This is the reason we have to know more information about psoriasis causes which is related to skin.
Taking care of the skin involves protecting the skin, keeping it moist, and using prescribed medicines. These steps will improve the condition of the skin.
