一篇关于生物方面的英文文章(200字左右)
Gene therapy is defined as the introduction of genes into tissues or cells via gene transfer, with the purpose of deriving a therapeutic or preventative benefit from the function of these genes. Gene transfer is achieved using a vector ? a kind of vehicle that carries the gene. Somatic gene transfer only targets body cells (somatic cells). Introducing genes into the germline is illegal in Germany. The first well-documented gene therapy studies were launched in the early 1990s. By 2005 it was estimated that more than 1,100 gene therapy studies had been conducted worldwide, one-third of them in Europe, and a significant number in Germany. The DFG is currently funding a Priority Programme for research groups, some of which are international leaders in their field, that examine the entry and persistence of gene therapy vectors in target cells.
