Treatment of Immune-mediated Brain Swelling with Combined Anti-LFA1/VLA4 Therapy
This technology includes a therapeutic approach to prevent secondary edema after cerebrovascular hemorrhage. Using an animal model, we found that edema is triggered by massive extravasation of myelomonocytic cells from the blood into the brain in response to hemorrhaging vessels. Administration of anti-LFA1 and anti-VLA4 antibodies resulted in an inhibition of extravasation of the myelomonocytic cells. This single dose treatment prevented secondary edema and markedly improved functional outcomes if administered within the first six hours following cerebrovascular hemorrhage.
