蛋白质的性质似乎要比生物学家们所想的更加复杂多变。美国西雅图州癌症研究中心的人员发现不仅癌变细胞能够对蛋白质分子进行“切割”和重组,甚至连正常的细胞也能够如此。细胞所具有的这种能力不仅能够提高生物自身的免疫力,而且有助于研究人员了解免疫系统是如何重组那些受过细菌或病毒攻击的细胞。 The nature of the protein seems to be more complex and varied than biologists thought. Scientists at the Seattle State Cancer Research Center discovered that not only cancerous cells can “cleave” and recombine protein molecules, but even normal cells. This ability of cells not only improves the organism’s own immunity, but also helps researchers understand how the immune system recombines cells that have been attacked by bacteria or viruses.
