Blossom of CRISPR technologies and applications in disease treatment.

Since 2013, the CRISPR-based bacterial antiviral defense systems have revolutionized the genome editing field. In addition to genome editing, CRISPR has been developed as a variety of tools for gene expression regulations, live cell chromatin imaging, base editing, epigenome editing, and nucleic acid detection. Moreover, in the context of further boosting the usability and feasibility of CRISPR systems, novel CRISPR systems and engineered CRISPR protein mutants have been explored and studied actively. With the flourish of CRISPR technologies, they have been applied in disease treatment recently, as in gene therapy, cell therapy, immunotherapy, and antimicrobial therapy. Here we present the developments of CRISPR technologies and describe the applications of these CRISPR-based technologies in disease treatment.
