Mechanisms of Resistance and Strategies to Combat Resistance in PD-(L)1 Blockade

Regulation of PD-1/PD-L1 pathway and resistance to PD-1/PD-L1 blockade

Immune checkpoint blockades, such as inhibitors against programmed death 1 (PD-1) and its ligand (PD-L1), have received extensive attention in the past decade because of their dramatic clinical outcomes in advanced malignancies. However, both primary and acquired resistance becomes one of the major obstacles, which greatly limits the long-lasting effects and wide application of PD-1/PD-L1 block...

Strategies to Combat Antibiotic Resistance

Microenvironment and Immunology Acquired Resistance to Fractionated Radiotherapy Can Be Overcome by Concurrent PD-L1 Blockade

Radiotherapy is a major part in the treatment of most common cancers, but many patients experience local recurrence with metastatic disease. In evaluating response biomarkers, we found that low doses of fractionated radiotherapy led to PD-L1 upregulation on tumor cells in a variety of syngeneic mousemodels of cancer. Notably, fractionated radiotherapy delivered in combination with aPD-1 or aPD-...

Novel Strategies to Combat Antimicrobial Resistance

Infectious diseases form the major health-care burden for the developing world and antimicrobials prove to be the magical drugs to combat this. The discovery of antimicrobial agents was boon for the global health-care system and the wonderful cure by antimicrobials shifted the disease trends from infectious to life-style diseases in the developed world. Sudden appearance of the antimicrobial re...
