Avoiding, Treating & Curing Cancer With the Immune System

UCSF immunologist Alex Marson on the frontier of cancer immunotherapy — using CRISPR to reprogram the patient's own immune cells to attack cancer. The revolution: rather than poisoning the body with chemotherapy, teach the immune system to find and kill cancer cells precisely.

Highlights

•

CRISPR-engineered immune cells can be programmed to attack specific cancers

Marson: his lab edits patients' T cells with CRISPR to recognize and attack their specific tumor. Early clinical trials show complete remissions in patients who failed all other treatments.

•

The immune system is the ultimate cancer defense — most cancers are caught and destroyed before they grow

Marson: your immune system kills pre-cancerous cells constantly. Cancer only grows when it evades immune detection. Immunotherapy re-enables the system that was already designed for this job.

Misc

✧Marson's work is among the most cited in immunology — Nature, Science, Cell papers regularly

✧The first CRISPR cancer trial in the US used cells from Marson's lab

✧He started as a physician seeing patients die of untreatable cancers — his research is motivated by those experiences
