into chimeric sequences that can all be read at once using high - throughput sequencing.
No. 4: CAR - T takes a backseat Research
into chimeric antigen receptor T - cell (CAR - T) therapy has captured the attention of investors over the past two years, but safety risks could emerge as trial sizes increase, and that could help shift attention to other promising anti-cancer approaches, including NantKwest's (NASDAQ: NK) natural killer cell approach and soon - to - IPO Editas» CRISPR / Cas approach.
