00:00Scientists may have just found a natural cancer killer that's safer, faster, and more effective than current treatments.
00:06A team at Harvard and MIT has created supercharged CAR-NK cells,
00:11a new kind of immune cell that can destroy cancer without the dangerous side effects of chemotherapy.
00:16These NK cells already exist in our bodies and naturally kill invaders without being trained,
00:21but researchers made them smarter and stealthier.
00:24They genetically engineered them to target cancer and avoid rejection from the body's own immune system.
00:31When tested on mice with aggressive tumors, the results were jaw-dropping.
00:35Standard treatments failed after two weeks,
00:38but these modified CAR-NK cells stayed active for three weeks and nearly wiped out the cancer.
00:43Even better, they don't trigger a severe reaction called cytokine release syndrome,
00:48which can shut down organs during chemo.
00:50And it only takes one extra step to create these supercells,
00:54making it possible to have ready-to-use treatments right after diagnosis.
00:58Experts believe this could replace traditional CAR-T therapies
01:01and possibly treat other diseases like lupus, too.
01:05This isn't just a breakthrough.
01:06It could be the future of cancer treatment.
01:08A little bit bigger, maybe notice it won't work until it...
01:28When we try to focus on that� 또 device like lupus,
01:33that will make sure that the system isn't...
