spec: Relations provide a way of comparing mathematical objects that can yield a Boolean value . Strikingly , the highly neurovirulent JHM strain of MHV fails to induce a CD8T cell response , resulting in the inability of the host to clear the virus from the brain . We are currently investigating why viruses expressing the JHM spike protein spread more rapidly than weakly neurovirulent strains in the CNS , yet fail to induce a robust T cell response . The final missing element of the nation 's power equation is renewable energy , the one sure shield against volatile fuel prices .
