How does the human body fight against tumor formation? The human immune system includes many kinds of immune cells, among which type 1 conventional dendritic cells (cDC1) are essential for effective anti-tumor immunity. It can recognize tumor antigen and induce the anti-tumor immune effect of CD8 + T cells. When cDC1 is absent, CD8 + T cell-driven tumor immunity will subside, and the therapeutic effect of CD8 + T cell…

A New Method of Rewriting the Genetic Code of Bacterial Genome Can Add Many Unnatural Amino Acids to the Protein At One Time
Almost all organisms build their proteins by combining 20 different amino acids. In order to add new amino acids to this combination, scientists have redesigned genes and other protein-building tools to produce proteins with unique chemical properties that are very helpful for the manufacture of drugs. However, this kind of research is time-consuming and laborious, and usually, only one new amino acid can be added at a time. Now,…
