Could microbes in our guts be sending out the wrong message? Queen's University Belfast researchers have, for the first time, found a specific microbe in the gut that pumps out protein molecules that mimic a human protein, causing the human defence system to turn on its own cells by mistake.
Two variants of an autoimmune disease that affects thousands but is hard to diagnose are relatively common among black Africans, research shows.
The findings, relating to systemic lupus erythematosus, or SLE, could improve diagnosis and treatment of the condition.
They could enable better management of the disease in patients of African descent, particularly in southern Africa, where incidence and mortality rates are relatively high.
