In the year 1989, two students from a Free University of Brussels were offered to test sensitive camel blood serum, and as they did, they were on an unknown antique bead. It was a small version of an anti-odor found in one human, and it was only two heavy protein chains instead of two heavy chains and two light chains. When reported, the spiders were found at & nbsp; camels confirmed to appear in lama & alpacas.

In Boston's current children's medicine, Children's Children's Hospital and MIT have shown that mini-anti-deaths have disappeared to make nanobody names, as in & # 39; e journal PNAS. This discovery can help bring the current problem to the cancer field, and this creates a CAR-T cell therapy in fixed tumors.

CAR T-cell therapy is very promising for blood animals, chimeric anti-receptor can genetically engineer a T cells of a patient to make them better when attacking cancer cells. The Dana-Farber / Boston children's circle and bloodshed is currently killing CAR T-cell therapy, it becomes useful for necessary acute lymphoid leukemia and that is only one of the illnesses that can limit it .

However, CAR T cells have been reported not to be as effective in reducing solidified tumors. It is difficult to find proteins on solid tumors that are cancer-specific and can serve as safe targets. Fixed tumors are protected by a matrix that is extra-cellular, which means that it has a valuable web of proteins that can act as a barrier and the T-cell attacks due to the immunosuppressive molecules may be weak.

That's where nanobody comes in and does their job. For over 20 years, they remained in the care of the Belgian team. But that all changed to the patient that they were lost in 2013.

"Many people got into the game and began to distinguish from unique nanobodic features," says Hidde Ploegh, Ph.D., an immunologist in the program in Cellular and Molecular Medicine in the Boston Children's Book and senior researcher on PNAS study.

One useful contribution to having the nanobodys is their enhanced preparation of skills. Ploegh and his team at Boston Children & # 39; s, in association with Noo Jalikhani, Ph.D., and Richard Hynes, Ph.D. At the MIT's Integrated Cancer Research Integration Institute, other people have been involved in carrying agency agents, making ordinary metastatic connoisseur visualization.

The Hynes team focused on & # 39; e extra-cellular matrix or ECM. They target the image agent from the nanobodies to the cancer cells directly & # 39; an environment it encircles. These markers are very common for many tumors, but they do not appear on normal cells.

"Our laboratory and the Hynes laboratory are actively pursuing this approach of targeting the tumor microenvironment," says Ploegh. "Most labels look for tumor-specific antigens."
