Attacking cancer indirectly: Generating immunity against tumor vessel protein in mouse study
- ScienceDaily
- 14/4/25 22:21
A novel DNA vaccine is being trialed to kill cancer, not by attacking tumor cells, but targeting the blood vessels that keep them alive. The vaccine also indirectly creates an immune response to the tumor itself, amplifying the attack by a phenomenon called epitope spreading. The team injected mice with a DNA fusion vaccine. In mouse models of three cancer types, tumor formation was delayed or...
'Beneficial inflammation' may promote healing in pulmonary fibrosis
- ScienceDaily
- 14/4/25 19:40
Inflammation has long been considered an integral part of the biological process that leads to deadly scarring in idiopathic pulmonary fibrosis. New research, however, suggests that a little inflammation may also be crucial to the healing and repair processes in the lungs. "The role of inflammation in the development of scarring has been hotly debated in recent years," said one researcher. "Our...
Genome regions once mislabeled 'junk' linked to heart failure
- ScienceDaily
- 14/4/25 19:40
Large sections of the genome that were once referred to as 'junk' DNA have been linked to human heart failure, according to research. So-called junk DNA was long thought to have no important role in heredity or disease because it doesn't code for proteins. But emerging research in recent years has revealed that many of these sections of the genome produce RNA molecules that, despite not being...
