噬菌体T4是一种具有众所周知的遗传学、结构和生物学的病毒。诸如X射线晶体学、冷冻EM和三维(3D)图像重建等技术允许非常精确地描述其结构。该噬菌体的基因组被完全测序,这为许多分子技术的使用开辟了道路,例如广泛应用的位点特异性诱变,例如,在研究一些必需的T4蛋白的功能。噬菌体展示方法是噬菌体修饰中常用的方法,已成功地用于在T4的衣壳平台上展示抗原(PorA蛋白、vvIBDV的VP2蛋白以及炭疽和HIV的抗原)。如最初的研究所示,噬菌体展示系统以及位点特异性诱变也可用于修饰噬菌体颗粒与哺乳动物细胞之间的相互作用或获得除宿主细菌之外的感染性物种。除其他外,这些可用于不断发展的噬菌体疗法。对这种流行的噬菌体的所有操作都可能使疫苗技术、噬菌体治疗以及生物和医学科学的其他分支的发展成为可能。
Bacteriophage T4 is a virus with well-known genetics, structure, and biology. Such techniques as X-ray crystallography, cryo-EM, and three-dimensional (3D) image reconstruction allowed describing its structure very precisely. The genome of this bacteriophage was completely sequenced, which opens the way for the use of many molecular techniques, such as site-specific mutagenesis, which was widely applied, e.g., in investigating the functions of some essential T4 proteins. The phage-display method, which is commonly applied in bacteriophage modifications, was successfully used to display antigens (PorA protein, VP2 protein of vvIBDV, and antigens of anthrax and HIV) on T4’s capsid platform. As first studies showed, the phage-display system as well as site-specific mutagenesis may also be used to modify interactions between phage particles and mammalian cells or to obtain phages infecting species other than the host bacteria. These may be used, among others, in the constantly developing bacteriophage therapy. All manipulations of this popular bacteriophage may enable the development of vaccine technology, phage therapy, and other branches of biological and medical science.
