Can kill the cancer cell while stimulating the defective immune system

It is reported that organizes the report on February 26 of network according to the American physicist, Lip river of Chicago of U.S.A. nearly draws university researchers and studies a new technology, through being and infected with the experiment in the human T cells of HIV virus in the little mouse of immune tendency towards compromise, can stimulate the defective immune system effectively, it is expected to turn T cells into a more effective weapon, resist various infection even cancer. The relevant thesis is issued on latest a " natural medical science " magazine.

Thesis senior author, Chicago Lip river nearly draw tumour Joe, associate professor of institute of university Stritch medical college Sri Lankan Guevara - Petty's promise and say, in the infeted and cancer patient body of HIV virus, T cell usually inhibited. This technology is mainly a section of DNA order cell submitted to immune system once, instruct them to produce a kind of special protein, and these proteins can stimulate T cells.

The target who they study is that CD8T cells and the antigen present cells, it is the order cells of CD8T cells to present cells with antigen. After CD8T cells have got the instruction of order cells, need to get aid of other T cells and could make strongly, go to kill those and is infected with cells or cancer cells, and maintain vigilance while encountering the pathogen or cancer cell again. The thesis leads one of the authors Andrew Laura explains now, tumour has many latent skills, among them the most important one prevents T cells from attacking tumour. They can make other T cells at inhibiting stage, have limited its aid of CD8T cells.

Researchers deliver a small Section DNA into skin order cell with the genetic rifle, this section of DNA can instruct order cells to produce special protein just like a kind of molecule key. When CD8T cells interact with order cells, the key will open the latent energy of CD8T cells, activate them and kill pathogen and cancer cell. Through this kind of technology, T cell no longer need help of other T cells while killing the pathogen and cancer cell. Even if tumour has put T cells that these played a helping role into " The cage " ,T cell can be set out and killed the cancer cell.

Researchers still say, hope to spend this technology on more disease research in the future, including cancer, it is estimated that begins to carry on the clinical trial to the cancer patient in 3 years. (often beautiful monarch)
