This was biology that was beyond art. The glass incubator that was on one side of the lecture room was like an installation. APD, the immune checkpoint inhibitor, went into the tumor on the organoid. The APD rushed to the surface of the cancer cell and attached to PTLA-L1, the immune cell shutdown factor.0

Young-Joon turned on the live cell imager and connected it to the incubator. A magnified version of the tumor showed up on one side of the monitor. It still seemed like a static mass of tumor. However, there was a lot of work going on in the microscopic world. Changes began to occur inside the cancer cells as a large amount of PTLA-L1 was neutralized.0

—It’s going crazy.0

Rosaline sent a message. She was outside of Young-Joon’s body and observing that phenomenon.0

By nature, organisms wanted to maintain a certain base level; this was called homeostasis. As such, if something was activated in the organism, there was bound to be a reaction.0

In the case of cancer cells, the response to PCLA inactivation was the expression of EGFR. However, this EGFR was mutated, unlike regular cells. It malfunctioned by continuously...0
