In 2003, researchers at Imperial College London tested a drug that interferes with a “survival signal” that keeps activated T-cells working at the site of inflammation during influenza infection in mice. The signal, another cytokine designated OX40, essentially disables the brakes on the T-cell response. By blocking the OX40 receptor on T-cells, researchers were able protect mice from the serious symptoms of virulent flu (paper in J. of Experimental Medicine and reported in New Scientist). The drug, to be made by a company called Xenova Research, was supposed to be in phase I clinical trial in 2004, but we have no further information of its status (additional information solicited for this entry).
