U.S.A. finds the cancer cell can be hidden in animal's immune system
According to Xinhua News Agency American researchers were in the academic periodical a few days ago>On if you can't announce by mouse is it experimental, study to reveal whether can find cancer cell by hiding-place on immune system. After why undergo chemotherapy this discovery can be explained, tumour can also stage a comeback.
The researchers of American Massachusetts Institute of Technology have studied the experiment mouse who suffer from Birket's lymphoma, this disease is a kind of highly malignant B cell tumour. After utilizing standard chemotherapy medicine A mouldly to usually treat, tumour of the experimental mouse has really dwindled. The researcher dissects the experimental mouse subsequently, excise all important lymphocytic organs such as its thymus, spleen and peripheral lymphocytic organ, in order to analyze chemotherapy focal influence to tumour.
Researchers find, except that thymus, has not found tumour cells in other lymphocytic organs. But the cell quantity of tumour in the thymus has increased than before chemotherapy instead. The thymus is body of an important gland, can produce the immune cells which is called T cell. Researchers have fostered the thymus smaller in disorder experiment mouse, they accept the survival rate after chemotherapy in Birket's lymphoma of suffering from, be better than the ordinary experiment mouse. This is confirmed from the side too, the thymus may protect tumour cell on function.
The intersection of director and the intersection of Michael and hertz of research this say gracefully, laboratory research indicates, the thymus can secrete the special chemical material, protect ripe cell from being poisoned . The cancer cell exactly utilizes this to find the ideal hiding-place. But if expect to use this discovery for human cancer to study, need to carry on a lot of clinical trials.
