Sun exposure can induce, or reduce, the incidence of certain autoimmune disease

It's an interesting conundrum: The effects of ultraviolet (UV) radiation from sun exposure can induce the onset of, or exacerbate, the symptoms of certain autoimmune diseases. Now flip the coin: UV also can prevent, or reduce, the symptoms of others. Current research focuses on lupus, multiple sclerosis (MS), type 1 diabetes, rheumatoid arthritis, inflammatory bowel disease, dermatomyositis, and atopic eczema.

What is going on? "These irradiations may alter the delicate regulatory network of the immune system to ...
