Most experts consider<unk>  an autoimmune disease since pathologists see antibodies when they biopsy the lesions and look at the tissue under the microscope. However, scientists do not understand the connection between these antibodies and the lesions seen in<unk>  lupus. Possibly, UV light damages skin cells, which then release material from their nuclei. This material diffuses to the dermoepidermal junction, where it binds to circulating antibodies, thereby leading to a series of inflammatory reactions by the immune system. Alternatively, dysfunctional T cells may lead to the disease.
