eliminate the residual cancer
cells that often form new
tumors following surgery.
As an additional safety feature, the researchers introduced two mutations that weakened the virus's ability to combat the
cell's defenses against infection, reasoning that the mutated virus still would be able to grow in
tumor cells — which have a poor antiviral defense system — but would be
eliminated quickly in healthy
cells with a robust antiviral response.
The effects of consuming emulsifiers were
eliminated in mice devoid of microbiota (germ - free mice), and transplanting microbiota from emulsifier - treated mice to germ - free mice was sufficient to transfer alterations in intestinal epithelial
