U.S.A.'s research indicates carbon nanotube can strengthen the ability to resist cancer of disease effectively

U.S.A.'s research indicates carbon nanotube can strengthen the ability to resist cancer of disease effectively
Organizing the network report according to the American physicist, the engineers of Yale University find, the gap on carbon nanotube can impel T cells (a kind of leucocyte) The antigen assembles in the blood, and stimulate human one's own immunoreaction, thus improve the present commonly used immune treatment of succession, strengthen the ability to resist cancer of disease effectively. Relevant research is released in 4 U.S.A. published on the 20th in moon>(Langmuir) On the magazine .
The immune treatment of succession, are also called the cell and shifted the treatment, mean that draws cells in the immune system from patient's body, improve, make it directed it against the patient's particular disease more effectively, inject them into the patient's immune system again subsequently, bring out the corresponding cells of disease in order to attack. Though it is human last T cells against tumour too by oneself,its can tumour " L Suppress " ,And effective cells are very limited in quantity. Quantity and quality that can guarantee T cells effectively that and adopt the way of cultivating outside the body, reach better anticancer result.
Have reported carbon nanotube before the research group to the unexpected result proliferating T cells too. Will certainly find in the total number of the antigen by they, make carbon nanotube into " L The coat " R Attached to antigen surface, can make the intersection of T and cell proliferate speed, far higher than antigen polystyrene cultivation speed at the membrane parcel that material make. It can be in carbon nanotube because of the antigen that this is " L The gap " R Assemble, thus reach better proliferating the result.
Main author, chemical equation of Yale University and auspicious gram of France rice of tower of associate professor of the biomedical engineering department of the thesis say, it is similar to microenvironment of the lymph node that carbon nanometer is restrained, have complicated geometirc structure, it can imitate physiology and absorb more antigen, stimulate stronger immunity and react. Will the intersection of carbon and the intersection of nanotube and traditional method used for human body can cause issues such as thromboembolism,etc., but while putting carbon nanotubing into blood and cultivating cells, do not involve planting it into body, so there is no similar problem.
The experimental data indicate, the immune treatment of succession needs to cost several weeks and producing enough T cells, and carbon nanotube can be produced with the succession cells of equal quantity of immune treatment within 1/3 of the time. Researchers say, this is a new way to explore the unique properties of carbon nanotube, also innovation in safe application of the biological field of carbon nanotube. The next step, studying the group will set about exploring as the effective, way to remove carbon nanotube in the blood, supply the blood to disease in the body again subsequently.
