The NYU Langone Health researchers and its Perlmutter Cancer Center developed a drug that reportedly eliminates cancer cells while maintaining healthy ones.
It is an antibody that targets the mutant protein called HER2 without attacking normal ones.
As a result, it can treat people without causing unintended health effects.

Dr. Shohei Koide, PhD, a professor in the Department of Biochemistry and Molecular Pharmacology at NYU Grossman School of Medicine, stated:

Eventually, they found variants that recognized the mutant HER2 and not the normal version.
Then, they converted their antibody into a bispecific T-cell engager.
It is a molecule where an antibody targets the mutant protein fuses with another antibody that binds to a T-cell and activates them.
One end of the antibody sticks to the mutant HER2 on a cancer cell. Meantime, the other causes T-cells to kill the cancer cell.
Further testing revealed that the method killed mutant HER2 cancer cells and spared normal ones.
Moreover, it reduced tumor growth significantly when the researchers tested their T-cell engagers in mice with mutant HER2.
The drug did not cause weight loss or visible sickness, suggesting it causes few side effects.

Dr. Koide noted that differences between mouse and human proteins require further research to confirm their impact on people.p333 casino
