Columbia Engineering researchers report that they have developed a “cloaking” system that temporarily hides therapeutic bacteria from immune systems, enabling them to more effectively deliver drugs to tumors and kill cancer cells in mice.

Founded by Nobel prize winner Emmanuelle Charpentier, CRISPR Therapeutics has been at the forefront of the gene editing technology and has refined it to the point where it can be used to accurately edit DNA to correct genetic conditions or modify cells to fight disease.
The company is on track to fulfill the 200 million-dose order put in by the US government by May, but hopes to have more available as engineers improve systems on the go. As soon as vaccine vials began coming off the production line, engineers started analyzing how production could be made faster and better. coli bacteria.
But scientists at the University of California (UC), Santa Barbara, believe fluoride may offer hope in the fight against antibiotic-resistant bacteria. “Essentially, what Justin did was to create a series of DNA instructions you can give to cells that will enable them to survive when fluoride is around,” said O’Malley.
coli bacteria, as well as lambda bacteriophage, can adapt to the alterations in the composition of their nutrient medium. Gene switches can be regulatory proteins or specific DNA sequences that act to either switch on or off the expression of a gene.
The company’s suite of market-leading molecular profiling offerings assesses DNA, RNA and proteins to reveal a molecular blueprint that helps physicians and cancer patients make more precise and personalized treatment decisions.
Some have argued bacteria are developing antibiotic resistance faster than we can research, develop, test and approve new antibiotics. One possible solution to antibiotic resistance: bacteriophages (or phages), which are viruses that infect bacteria. These resistance genes are commonly found on small circles of DNA called plasmids.
Doudna, PhD, of the University of California, Berkeley and Emmanuelle Charpentier, PhD, of the Max Planck Unit for the Science of Pathogens Institute for Infection Biology, revolutionized genetic research by helping to identify a natural gene editing mechanism in bacteria.
