Explanation:
Oligoclonal expansion does not occur only in this pathology, it also occurs in other recurrent diseases such as multiple sclerosis, this phenomenon is widely studied and little discovered in some aspects and is mainly based on both tcd4 and tcd8 and b lymphocytes.
In this case, the presence of ltcd4 in psoriasis is very versatile and depends on the patient's immune response, which is why more scientific evidence is needed on this topic, based mostly on meta-analyzes.
