I used to suffer from psoriasis. At the beginning, I just had a few red spots the size of beans on my arm. Later, it gradually developed into a white plaque. Sometimes it itches. Now many people suffer from psoriasis. Do you want to know what genetic disease psoriasis is?

Is psoriasis any hereditary disease

First of all: psoriasis also has a certain genetic probability, it is generally believed that the disease is autosomal dominant inheritance, with incomplete penetrance. It is reported that 10% - 23.8% of the patients have family history in China. The prevalence rate of family disease is much higher than that of the general population.

Secondly: bacterial infection is also one of the causes of diseases. Streptococcus is the most likely bacteria to cause diseases. This kind of bacteria is everywhere in our daily life. It is impossible for us to avoid it completely. The best thing is to increase the body's resistance to bacteria, so that bacteria can not invade the body.

Finally, it was found that the keratin extract of psoriasis vulgaris and pustular psoriasis contains complement component C3a, which can make neutrophils aggregate to the lesion and form micro abscess. T lymphocyte infiltration exists in the dermis of psoriasis. Activated T lymphocytes release cytokines to stimulate the proliferation of keratinocytes.
