Hi Dr. Landolfi;
I hope you had a great 4th of July!
Here is the next question from the group. First though, I want to pass on the sincere "thanks" expressed by many of the group members for your assistance.
Here is another basic question that a few of us were wondering about...
What is the Blood - Brain Barrier, and what steps are employed to breach it?
Thank you (as always)
Bruce
The doctor's response...
It is a layer of tightly approximated cells that filters the blood going to the brain. There are a few places it is not present. It is usually broken down in areas of tumor which is why we see enhancement in some tumors. Disrupters of the barrier have been attempted for decades with disappointing results, this includes direct injection into the cerebral blood flow.
