Groundbreaking research has identified Epstein-Barr virus (EBV) as a potential trigger for the autoimmune disease lupus, a breakthrough that could revolutionize treatments for this debilitating condition.
According to scientists, EBV is a common childhood virus that appears harmless, but can cause immune cells to "go rogue" and mistakenly attack the body's own tissues. The study suggests that 100% of lupus cases are linked to EBV, making it a key discovery in understanding the cause of this chronic autoimmune disease.
Lupus affects around 69,000 people in the UK, causing joint and muscle pain, extreme tiredness, and skin rashes. The causes have long been unclear, but epidemiological surveys had previously hinted at a link between EBV and lupus. The latest research confirms this connection by shedding light on how EBV sends the immune system into a tailspin.
The study found that B cells, part of the immune system, are infected with EBV in 25 times higher proportions than healthy individuals. This is significant because these "autoreactive" B cells can mistakenly target parts of the body's own cells. When EBV infects these cells, it activates them to drive an autoimmune response that mediates lupus.
While this finding does not mean that EBV is solely responsible for lupus, it provides a crucial clue in understanding the disease. Other risk factors, such as hormonal fluctuations and genetic predisposition, also play a role in susceptibility.
The research has sparked excitement among scientists, with one professor stating that the findings are "impressive" and could lead to new treatments. A vaccine against EBV is already being developed, and several teams are exploring repurposing cancer treatments designed to wipe out B cells for severe cases of lupus.
In a significant breakthrough, this study resolves a decades-old mystery surrounding lupus and provides hope for future therapies. The discovery opens up new avenues for treating the condition, potentially improving the lives of millions of people affected by lupus worldwide.
