Is There a Killer Virus in a Mouse With a Virus?

Lymphatic vessels, get bigger and more e more of them, just before you infect the mouse with the virus. They don't really talk aboutd i don't know how the valves work. Is it one way? Thoug i think you can regulate flow by the valves, right? The other interesting experiment that i thought would have been nice for them to do would have been to do the veg f c treatment and then have a condition where they do that posseligation to show that, like, it's actually n target effect.
