MIT engineers an anti-cancer smart bomb

...nimals died at 20. "It's an elegant technique for attacking the two compartments of a tumor, its vascular system and the cancer cells," said Judah Folkman of Children's Hospital Boston. "This is a very neat approach to drug delivery," said MIT Institute Professor Robert Langer. The nanocell worked better aga...

Disabling gene defuses rheumatoid arthritis in mice

...cus either on preventing wayward immune cells from attacking the joints or on reducing the ability of these cel...ive cells from the body's immune system mistakenly attacking healthy joint tissues. Scientists once thought the cells that were most active in these attacks were...

Fox Chase study shows that weakened T-cell receptor signals change T-cell lineage

...st external agents (helper T cells) or by directly attacking and destroying cells infected by foreign invaders (killer T cells). Gamma-delta T cells migrate from the thymus to epithelial tissues such as skin and the linings of the lung. While their precise role remains poorly understood, they perform vital pro...

Anti cancer virotherapy well tolerated in first human administration, research finds

...afren's research has shown EV1 to be successful in attacking aggressive ovarian cancer cells in the test tube and infected mice . ### Psiron is an anti-cancer biotechnology company focusing on virotherapy. Psiron is developing a suite of viruses for treatment of a range of cancers. Research and development i...

Mayo Clinic Researchers Create 'Obedient Virus'; First Step To Use Measles Virus Against Cancer

...gy. The researchers harnessed the viral trait for attacking and commandeering cells, and then redirected the virus to attack diseased, rather than healthy cells. The work was done on laboratory animals implanted with two kinds of human cancer cells -- ovarian cancer and lymphoma -- and is probably still years...

Falling ants glide back to trunk to avoid dangers of forest floor

...ak casually brushed off a few dozen ants that were attacking him and noticed their uncanny ability to land on the tree's trunk and climb back to the very spot from which they'd fallen. "I brushed them off the branch with my hand, and I noticed that maybe 20 or 30 of them fell in unison and then made this nice...

Circles Of DNA Might Help Predict Success Of Stem Cell Transplantation

...T cells to divide and multiply in order to form an attacking army. However, the sjTRECs don't multiply when the original T cells divide and multiply. Instead, the more T cells that are produced in the blood as the parent cells containing sjTRECs divide and produce daughter cells, the more the sjTRECs in those ...

Computers to be used to find blueprint for new influenza drug

...mes infected. The flu virus would be deceived into attacking the drug, called an inhibitor, instead of the cells. The three-year project will be largely carried out by examining the behaviour of atoms of the influenza virus which attack cells, and atoms of the throat cells that are attacked. By using advanced...
