- Cancerul renal ramane un etalon "de succes" pentru imunooncologieprin achizitiile semnificative terapeutic, care au plecat de la terapia traditionala citokinica a anilor anteriori si a ajuns la imunoterapia moderna bazata pe inhibitorii punctelor de control.

Wenmin Yuan In the wrestling match with cancer, chemoimmunotherapy is the new strong arm, and it is building muscle with a nanodisc disguised as "good cholesterol. The nanodisc is made of a synthetic version of high density lipoprotein HDLalso known as " good cholesterol. Moon, Ph.
In multiple mouse tumor models of colon cancer, researchers found up to 85 percent of the tumors were completely eliminated when combining the nanodisc-delivered chemotherapy with immune checkpoint blockers, a common immunotherapy treatment. In a more challenging model of cancer, one that metastasized to the liver, the treatment also showed an excellent response rate of 88 percent.
To determine if cells are harmful to the body and need to be attacked, the immune system uses certain molecules called checkpoints.
Delivering cancer treatment on a nanodisc helps eliminate tumors
But some cancer cells avoid an immune system attack by producing proteins that trick the checkpoints. Checkpoint blockers were designed to allow immune cells to kill cancer cells.
These immunotherapy treatments are highly successful in some patients, but only about 20 percent renal cancer immunotherapy benefit. By using the synthetic HDL, which mimics natural HDL in the body, the researchers were able to hide the chemotherapy from the immune system. James Moon, Ph.

The immune system was empowered to recognize and attack tumor cells. There renal cancer immunotherapy no overt side effects to renal cancer immunotherapy new delivery system.
And interestingly, the researchers discovered another unexpected benefit: less impact on the heart. But we found that by delivering doxorubicin on the synthetic HDL nanodisc, we saw better accumulation of the drug in oxiuros uc tumor and we didn't detect any cardiotoxicity," Schwendeman says.
That may have contributed renal cancer immunotherapy the absence of cardiotoxicity," she adds, renal cancer immunotherapy that more research is needed to confirm that speculation.

Our results demonstrating their efficacy in multiple tumor models suggest that our strategy may have wide renal cancer immunotherapy in renal cancer immunotherapy cancer types," Moon says. Phase I clinical trials have been conducted for the synthetic HDL nanodisc, which has been determined renal cancer immunotherapy be safe, Moon says.
Next, the researchers are working to test the therapy on humans in clinical trials.
