Washington: Scientists claim to have found that a rare immune cell helps the immune system "remember" an attack, a key finding which may pave the way for new and moreeffective treatments for immune disorders. A team at the Walter and Eliza Hall Institute says the cells, called T follicular helper cells, represent less than half of one per cent of all immune cells, but play a key role in antibody production and developing long-lasting immunity. However, the cells are also dramatically increased in chronic inflammatory disease, suggesting that they could be a therapeutic target for treating these diseases. The team, led by Dr Katja Luthje, discovered a means of identifying the rare T follicular helper cells while they are actually involved in instructing immune response, revealing for the first time the possible fates of these cells.
