When we talk about One Health, just what do we mean? On its own, the phrase can be interpreted to mean many things, but for what we do in the biotechnology field, it encompasses human and animal health and disease, along with related environmental and epidemiological components. Essentially, it defines how people and animals interact with, and within, our shared environments, especially in reference to health and developing treatments for diseases.

CRISPR/Cas9 is a vital part of our research at the University of Minnesota and the Cas9 recombinant protein, used at high concentration, has allowed for highly efficient modification of T-cells.
By introducing a Cas9 nuclease guide RNA complex (RNP), we target a specific spot in the genome, where the nuclease cuts the DNA. The DNA break is repaired in one of two ways: homologous recombination, which is high-fidelity, or non-homologous endjoining (NHEJ), which is more error-prone.
