ici therapyPosted by catalina on January 6th, 2024 Immune Checkpoint Therapy in CancersImmune checkpoints consist of stimulatory and inhibitory pathways that maintain self-tolerance and assist with immune response. In cancer, immune checkpoint pathways are often activated to inhibit the nascent anti-tumor immune response. Immune checkpoint therapies act by blocking or stimulating these pathways and enhance the body's immunological activity against tumors. Cytotoxic T lymphocyte-associated molecule-4 (CTLA-4), programmed cell death receptor-1 (PD-1), and programmed cell death ligand-1 (PD-L1) are the most widely studied and recognized inhibitory checkpoints for cancer treatment. Drugs blocking these pathways are currently utilized for a wide variety of malignancies and have demonstrated durable clinical activities in a subset of cancer patients. Immune Checkpoint Therapy in Infectious DiseasesImmune checkpoint blockade has revolutionized the treatment of cancer with remarkable success. A number of studies have revealed that immune checkpoint blockade may also be highly relevant for treating several infectious diseases, including malaria, HIV infection, HBV infection, and tuberculosis. The up-regulation of PD-1 and CTLA-4 on immune cells occurs during both acute infections and chronic persistent viral infections. Learn more: ici therapy Like it? Share it!More by this author |
