Kariko and Weissman immediately realized that their discovery was of enormous significance for the possible use of messenger RNA in medicine. These important findings were published in 2005, 15 years before the outbreak of the Corona epidemic.

It seems that leumicron has the ability to bypass existing immunity, either from a vaccine or in convalescents. However, it appears to be more difficult to cause severe disease in those vaccinated with the booster shot and therefore

This is how the body sets up a unique emergency team against stroke using RNA-guide fragments

Guide RNA fragments, which until recently were known as stages of breakdown of the guide RNA on the way to their elimination from the body, were discovered in a new study led by Prof. Hermona Sorek from the Hebrew University, as molecules of great importance for preventing the collapse of the immune system following
3. In the diagram: on the left: the vaccines. mRNA vaccines are based on introducing artificial mRNA into cells so that it will serve as a template for building the viral protein that will activate the immune system. Shortly after the entry of the mRNA molecules into the cell, they begin to initiate the production of the immune proteins required by the cell. mRNA contains several chemical changes, which improve its activity in the cell. Right: the natural mechanism. The study published in Nucleic Acids Research shows how similar chemical modifications, naturally present in mRNA, serve as binding sites for regulatory factors. This link affects the activity of the ribosome and thus enables the production of proteins in more precise quantities and in accordance with the needs of the organism.

Dynamic, sophisticated and sensitive to the environment: this is how the mRNA formulates its instructions to the ribosome

In transgenic mice, which lack microRNA in nerve cells that innervate muscles, only the muscle staining is visible (above, in red), because the nerve in the junction area is diseased.
