Because a number of lung diseases follow respiratory tract infections, ascertaining whether a virus can be implicated in the events leading to sarcoidosis remains an important area of research. Some recent observations seem to provide suggestive leads on this question. In these studies, the genes of cytomegalovirus (CMV), a common disease-causing virus, were introduced into lymphocytes, and the expression of the viral genes was studied. It was found that the viral genes were expressed both during acute infection of the cells and when the virus was not replicating in the cells. However, this expression seemed to take place only when the T-cells were activated by some injurious event.
