What are the causes of psoriasis

Reason 1: it is generally considered 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.

Reason 2: bacterial infection is also one of the causes of diseases. Streptococcus is the most likely bacteria to cause our diseases, and this kind of bacteria is everywhere in our daily life. It is impossible for us to completely avoid it. The best thing is to increase the body's resistance to bacteria, so that bacteria can not invade the body.

The third reason: 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.
