Recombinant human Monocyte differentiation antigen CD14 by the trait to their offspring

A new study by researchers at the University of Washington School of Medicine in mice showed that, DNA of bacteria living in the body, and can be a way similar to the parent's own DNA, a trait will be passed to offspring. The author believes that this discovery means that a significant new factor scientists studying "how genes influence disease and health", the need to consider - microbial DNA passed from mother to child. Commensal bacteria influence such as weight, behavior such traits. But until now, researchers believe that the Recombinant human Monocyte differentiation antigen CD14  http://www.cusabio.com/protein-Recombinant_Protein-1031647/ effects are in the process of life of a person obtained. This is the first show, DNA of bacteria can be a way to pass from mother to offspring, the impact of specific traits, such as immunity and inflammation.

Researchers mice symbiotic bacteria and animal susceptibility to intestinal injury linked. Mice having a certain genetic bacteria susceptible to damage, which is by exposure to chemical substances caused. Female mice can transmit the bacteria to their offspring, making them vulnerable. While other mice carrying different bacteria are less affected. In the short term, these findings may help scientists study transgenic mice eliminate an important "error." In many areas of research, scientists have been faced with the sudden emergence of intermittent, mice often unexplained new or altered traits. Characters usually spread from one habitat to another mouse, shows that the spread of microbial infection is the cause. But the trait has been passed from mother to offspring, thus suggesting a genetic cause.

When scientists will have low levels of mouse antibodies have high levels of antibodies in mice and mixed in captivity, in a few weeks all the mice have low levels of antibodies. These mice when they were hybridized offspring mother has a low level of antibodies generated, also have low levels of antibody. Eventually, scientists have learned that one of the culprits causing the spread of low-level antibody may be a bacterium called sutterella. The bacteria present in low IgA and other bacteria in mice can be explained in two ways low antibody levels spread: mice were mixed together in captivity, through the spread of bacteria normally get a low antibody levels, the mother put the same mouse The bacterium is passed to their offspring.
