Target behind cancer drug shown to help fight influenza in mice
A protein already targeted by FDA-approved cancer drugs may also help the body fight influenza, according to new research from The Jackson Laboratory (JAX).
Published in Cell Reports, the study found that Programmed Death-Ligand 1 (PD-L1), a protein best known for helping tumors evade immune attack, instead helped immunocompromised mice clear flu-infected lung cells and survive infection.
The findings challenge long-standing assumptions about PD-L1’s role in the immune system. While cancer therapies work by blocking PD-L1 to boost immune attack on tumors, the new research suggests that ...
