The gene code of dandruff was found

gene cellsThe international team of scientists who carried out the study hope that detailed knowledge of the genome of the fungus Malassezia globosa (Pityrosporum ovale) will lead to more effective treatments that would block its reproduction. Fungus lives and feeds on human skin, itching and flaking causing which are associated with dandruff. It is estimated that about half of the population suffers from dandruff, as men are more susceptible to developing this condition. Chapter on the human hand, the average quantity of this type of fungus is about 10 million. Fungus itself is fed by the sebum, which is produced by sebaceous glands in the skin. Sebum serves to protect the body from external influences, and particularly with regard to skin and hair, it protects them from this to become too dry, brittle and fragile. It turns out that Malassezia globosa is one of the simplest organisms that have ever tracked genetically and its only 4285 gene is 300 times smaller than the human genome. It will own ability to produce fatty acids which are vital for life and therefore relies on human sebum to exist.
The role of enzymes
Recent studies indicate that the fungus causes dandruff by producing enzymes called lipase. First it uses lipase degradation of sebum, thereby creating oleic acid. It penetrates the upper layer of skin and causes faster separation of skin cells in susceptible, which is manifested in dandruff. Researchers found that the fungus produces a total of 8 species Lipases along with three phospholipase, which used to absorb fats from the skin.
