Maybe this little pause is an opportunity for a reset — a chance for the scientific community to acknowledge that the CRISPR system, as some have quietly suggested all along, was actually «invented» by bacteria eons ago as an ingenious immune response to viral infection, and that its rediscovery was accomplished by so many heroic (if you will) hands and with so much public coin that the technology ultimately belongs in the public commons and should not be patented and...

Although this problem can, to some extent, be addressed by the use of reporter constructs (e.g. Diptericin - LacZ) that provide quantitative or visual read - outs from specific immune response genes, we still lack the ability to follow bacterial infections in real - time in the critical early stages of infection.

As part of the body's normal, healthy immune response to infection, the barrier formed by blood vessel cells temporarily loosens, allowing white blood cells to exit the bloodstream and attack the invading bacteria or virus, Rehman said.

In a typical immune response, for instance, inflammatory proteins called cytokines will be released by immune cells at a site of inflammation and then other immune cells will use these cytokines like a trail of breadcrumbs to home in on the site of infection and destroy the pathogens that are causing it.
