Here is more
good research from Fred Hutch. Several
research scientists at that worthy institution have discovered at least part of
the reason why immunotherapy techniques that work well to combat blood cancers are
less effective against solid tumors. It
appears that such tumors somehow recruit an army of what are known as T-regs –
meaning a type of T cell that down-regulates the ordinary sort of T cell which,
if left alone, might eat your liver, kidneys, etc. So, somehow, some solid tumors (including
OVCA) have “learned how” to protect themselves with an armor-plating of T-regs. How something like this could have evolved
naturally remains a mystery to me. I
continue to suspect the existence of a Devil!
In passing I
note that the PI on this study, although a Ph.D, looks like he belongs in
Middle School! Whole lot of smart young
people coming along. That gives me hope.
