To uncover the inflammatory pathways involved in cell injury and death, Kenneth Rock at the University of Massachusetts and colleagues injected necrotic cells into mice deficient in various toll-like receptors and found that neutrophilic inflammatory response was not significantly reduced.
"It's one of the first [studies] to really start looking at the molecular basis of the recognition of dying self-cells," says David Kranz, immunology researcher at the University of Illinois, and a member of the Faculty of 1000. Surprisingly, Kranz says, toll-like receptors, Tlr2 and Tlr4, which are critical in inflammatory responses to infection, were not key players in the inflammatory pathways involved in cell injury.
"Maybe now we can use that knowledge to ...
