Immune System Killer Mechanism Identified

traveller.ct writes “Researchers from Melbourne and London have

identified the mechanism by which the immune system destroys
malignant cells
. The notion of killer cells puncturing a
malignant cell to inject toxic enzymes has been understood for over
a century, but now, using the Australian Synchrotron, researchers
have identified the protein which is responsible for forming a pore
in the malignant cell: perforin. Perforin resembles the cellular
weaponry employed by bacteria such as anthrax, but may have been
appropriated by our immune system in our evolutionary past to fight
against them. The researchers are now investigating ways to boost
perforin for more effective cancer protection and therapy for acute
diseases such as cerebral malaria.”
