Now, in a study recently published in the journal PLOS ONE, a team of scientists from VCU Massey Cancer Center have shown a genetic relationship between the reactivation of hCMV and the onset of graft - versus - host disease (GVHD), a potentially deadly condition in which the immune system attacks healthy tissue following a bone marrow or stem cell transplant.

Because of the work of several other collaborators, Haughey says, his team knew that some sort of inflammation - promoting molecule was released from brain and targeted to the liver after brain injury to send immune system cells to the damaged area, but the identity of this go - between had been elusive for years.

Nevertheless, Hahm adds, it appears that «these cells are producing high amounts of suPAR, which becomes the mediator that communicates between the immune system and the kidney.

To measure the differences in immune system function between the two groups of older mice, the researchers examined the lungs to assess damage, counted the number of bacteria in the lungs, and calculated the number of the white blood cells (neutrophils).

Hence, we merged our expertise in evolutionary biology and immunology to study the complex interactions between the vertebrate immune system, composed of a myriad of different cells, and the gut microbiota, composed of another myriad of different bacteria.
