For the first time, neuroscientists
found lymph vessels in the brain area!
Not exact matches
In that spot, the scientists
found a niche of angioblasts, those same cells that a hundred years earlier were thought to be the source of
lymph vessels, but were later neglected.
They also
found evidence for blood and
lymph vessels in the dura of autopsied human brain tissue.
The researchers
found that the plasmalemma vesicle - associated protein (PLVAP), often used as a marker for blood
vessels, is expressed in
lymph nodes not only in the blood
vessels but also in the lymphatic
vessels that transport tissue fluids.
They administered a foreign protein subcutaneously and
found that the foreign protein was transported to the cells residing inside the
lymph node much more quickly when the lymphatic
vessels lacked the PLVAP protein.
In their paper published online in the Journal of the National Cancer Institute, an MGH research team reports
finding that the growth of metastases in
lymph nodes — the most common site of cancer spread — does not require new blood
vessels but instead takes advantage of existing blood
vessels.
Using a mouse model of cancer that provides direct microscopic access to
lymph nodes, they first
found that the initiation and growth of node metastases did not involve the development of new blood
vessels.
The
lymph system is
found in blood and tissues throughout the body; it is a network of
vessels and nodes through which foreign proteins and disease organisms are circulated.
For example, if a tumor is
found in the 4th gland, the vet may decide to remove the 3rd, 4th, and 5th glands on that side of the abdomen, as well as the inguinal
lymph node into which the
lymph vessels from those glands drain.
