The expression of PD-1 ligands on cancer cells is also mediated by cell-intrinsic mechanisms that are activated by oncogenic events, which result in altered activation of signaling pathways and ...

In 1992, graduate student Yasumasa Ishida discovered PD-1, marking the beginning of a journey that would make this molecule a ...

PD-1 plays a critical role in cancer immunotherapy and has become a prominent target in current tumor treatment approaches. Cancer cells have the ability to evade the immune system by exploiting ...

“We set up a screening program of our in-house natural product database against PD-1/PD-L1 signaling and identified a natural pentacyclic triterpenoid, Pygenic Acid A (PA), from medicinal plant ...

The CD28 signaling pathway also plays an important role in ... another prime reason CTLA-4 is a target for immunotherapy. PD-1 plays a vital role in maintaining physiologically-appropriate T ...

Keytruda is the first approved drug that blocks the PD-1 signaling pathway, which restricts the body’s immune system from attacking melanoma cells, and is intended for use following treatment ...

Co-cultivating the two cell lines induces activation of the Jurkat NFAT pathway via crosslinking of T-cell receptor (TCR) activator/TCR complex. PD-1 signaling in PD-1 effector cells following ...
