RNA

Transfer RNA has a crucial role in regulating immune response related to stroke.  Researchers at Goethe University in Frankfurt conclude:  “The immune system has a significant influence on the pathophysiology of a stroke; when the brain is injured, immune responses in the periphery of the body are reduced. That may limit the flow of immune cells into the central nervous system (and thereby keep inflammation low) as a protective mechanism. But this also raises the likelihood of complications like infection. That may happen because some tRNA fragments in cells called monocytes, which would normally release pro-inflammatory cytokines, can act to modulate that activity.”       MORE
