...wever, there is a risk that transplanted cells may recognize the recipient patient's tissues as foreign and begin to attack them. This reaction, known as graft-versus-host disease (GVHD), can be lethal if it continues unchecked. In the December 15 issue of the Journal of Clinical Investigation Robert Korngold ...SARS coronavirus part bird, part mammal: study

Several sets of signals work together to guide these budding nerve cells through each step. These cues act on the growing tips of axons, long narrow processes sent out by neurons in search of other nerve ...Gene mutation leads to super-virulent strain of TB
.... "It appears that the host immune system does not recognize the mutated TB organisms, so the bacteria are left to grow unchecked," said Morici. While the body typically summons granulomas to keep the TB bacteria from spreading and developing into an active infection, it does not completely eliminate the b...Plant immune system's 'take two aspirin' gene, offers hope for disease control

...important in the ability of CD4+ memory T cells to recognize and mount a response to previously encountered antigens. Approximately 1-4% of CD4+ T cells were shown to express VLA-1 and following T cell receptor activation the percentage of VLA-1+ cells increased. The authors found that CD4+ memory T cells that...University of Minnesota receives NSF grant to sequence legume genome
