  • PD-1 inhibition (Figure 1) has quickly become a front-line therapy for non-small cell lung cancer and melanoma . (shu.edu)
  • Most cancer cells have PD-L1 on their surface and escape being killed by turning off the T cell in this way. (shu.edu)
  • Accumulation of p27 in the nucleus, therefore, blocks cell cycle progression of T-lymphocytes that are being induced to act against cancer antigens. (shu.edu)
  • The goal of specific molecular targets in cancer therapy is to create a "magic bullet" that selectively kills cancer cells. (medscape.com)
  • As our understanding of the molecular biology of HNSCC continues to develop, we can target the specific components of cancer cells that are not found in normal cells. (medscape.com)
  • Ideal targets should be both specific to cancer cells and commonly found in cancer cells. (medscape.com)
  • Cells undergo cellular senescence to avoid the formation of cancer or other diseases related to a mutation in the cell due to any kind of stressors such as oxidative stress, telomere damage or epigenomic damage. (ijpsr.com)
