Clustered regularly interspaced palindromic repeats (CRISPR) technique plays a vital role in preclinical modelling of many respiratory diseases. Diseases such as chronic obstructive pulmonary disease (COPD), asthma, acute tracheal bronchitis, pneumonia, tuberculosis, lung cancer, and influenza infection continue to significantly impact human health. CRISPR associated (Cas) proteins, isolated from the immune system of prokaryotes, are one component of a very useful technique to manipulate gene sequences or editing and gene expression with significant implications for respiratory research in the field of molecular biology. CRISPR technology is a promising tool that is easily adaptable for specific editing of DNA sequences of interest with a goal towards modifying or eliminating gene function. Among its many potential applications, CRISPR can be applied to correcting genetic defects as well as for therapeutic approaches for treatment. This review elucidates recent advances in CRISPR-Cas technology in airway diseases.
