<title>1 Introduction</title>
<p>Gene and cell therapy has undergone transformative advancements since the first successful gene therapy in 1990, which treated a patient with adenosine deaminase deficiency. Over the decades, these therapies have demonstrated immense potential, yet the advent of CRISPR technology has marked a revolutionary shift in the field. CRISPR&#x2019;s simplicity, precision, and efficiency have reshaped genome engineering, driving the development of innovative therapies for genetic disorders, cancer, and infectious diseases. This editorial highlights the latest advancements in CRISPR technology, discussing its applications and the ongoing challenges in gene and cell therapy, with insights from recent research under the topic CRISPR&#x2014;The Game Changer.</p>

<title>4 Exploring research frontiers in CRISPR-based therapies</title>
<p>As the landscape of CRISPR research continues to expand, several promising avenues have emerged that hold transformative potential for gene and cell therapy. Continued innovation in developing new CRISPR enzymes and guide RNA scaffolds promises to enhance precision in genome editing, addressing the need for greater specificity in therapeutic interventions. Likewise, advancements in CRISPR-based genetic screening are facilitating the discovery of novel gene targets, an essential step toward refining therapies for complex diseases.</p>
<p>Further, the integration of CRISPR technology with cancer immunotherapy, particularly through CAR and TCR-engineered T cells, NK cells, and tumor-infiltrating lymphocytes (TILs), exemplifies CRISPR&#x2019;s growing impact on personalized cancer treatments. Research into optimizing delivery systems&#x2014;both viral and non-viral&#x2014;remains vital, ensuring targeted and efficient administration of CRISPR components in both <italic>in vivo</italic> and <italic>ex vivo</italic> settings. In clinical trials, CRISPR-based therapies continue to navigate challenges and reveal successes, highlighting both the promise and complexity of bringing these therapies to broader patient populations.</p>
<p>The connection between circular RNA and CRISPR is another emerging area, offering insights into new molecular mechanisms and therapeutic applications. Additionally, as CRISPR&#x2019;s potential to elucidate gene function advances, we are gaining a clearer understanding of disease mechanisms at a molecular level.</p>
