A vaccine against dental caries
We are all accustomed to vaccines. In early childhood, we make a vaccine against diphtheria, measles, whooping cough. Then inoculate hepatitis and other serious diseases. Annual influenza vaccination will not get sick from the cold weather. But scientists from China successfully tested another vaccine that will save from decay and the visit to the most "terrible" doctor. Dentist.
According to the most common at the present time of the theory, dental caries occurs because of the action of microorganisms Streptococcus mutans, that reside in the oral cavity. They produce lactic acid which leads to the formation of plaque, enamel destruction and the appearance of cavities. According to the journal Scientific Reports, researchers Wuhan Institute of Virology, Chinese Academy of Sciences, during its vaccine trials have achieved suppression of the microflora responsible for the development of caries. Experiments on the new vaccine on rats. The main component of the vaccine is a fusion protein KF-rPAc. It consists of KF protein that provokes an immune response to the protein rPAc. The latter is a structural element of the membrane Streptococcus mutans. Thus, the bacteria undergo carious more intense immune system attack. At the moment, Chinese scientists are planning the next phase of clinical trials involving humans.
It should be noted that attempts to create a vaccine against dental caries are held for more than three decades. The scientists used a variety of approaches. For example, in one vaccine research create a protective coating on the tooth surface, which prevented fixing bacteria on their surface.
