...nto the blood flow to recruit other platelets that attach in an organized matrix to stop the bleeding and maintain the vessel. Stroke, which results from abnormal clotting, is treated with blood thinning compounds to block platelets from forming clots.

The maytansinoids then can enter the cancer cells anddestroy them without damaging surrounding healthy tissue. "It is a warhead strategy," he said.

... storing it for future use. Some of the drugs they attach to folate, consequently, also are stored on the cancer cell surfaces. Taking advantage of this discovery, Purdue researchers and Endocyte scientists devised an alternative way to fight the cancer cells.

...This change presumably allows passing platelets to attach to vWF. Biology has many examples of such conformational changes that transform molecules from an inactive to an active state. People with von Willebrand's disease have an altered form of vWF, in which one amino acid in the protein has been replaced ...Sea Grant asking anglers to collect sea lampreys for Lake Champlain study

The next step, researchers say, will be to attach gene-based therapies to the virus, which would act as a vehicle to deliver the toxic treatment directly to the prostate cancer cells and, it is hoped, kill them.
