The finding provides a better understanding of the mechanisms behind bacterial warfare, which is the first step for the design of improved treatments fo more
The innate immune system may be able to be trained to react to viral infections more efficiently by repeated exposure to anti-viral signaling molecules. Mammalian cells seem to be able to memorize anti-viral stimulation at the level of DNA-packaging molecules, enabling faster and greater activation more
Just like humans, plants have an immune system that helps them fight off infections. Plant immunity has some important differences: they don't make antibodies and can't fight off the same bug more quickly months or years later. However, plant cells can identify pathogens and react to them, often by more

The cell surface protein CD47 functions as a self-recognition molecule on mammalian cells, sending a negative “don’t eat me” signal to macrophages and dendritic cells. When CD47 is missing from cells in circulation, they are promptly taken up by and cause activation of dendritic cells in the spleen, more
