Features: 
Immunotherapy is not one drug class. It includes:
-Immune checkpoint inhibitors (PD-1, PD-L1, CTLA-4)
-CAR-T therapies
-Monoclonal antibodies
-Cytokine therapies (IL-2, IFN-α)
-Cancer vaccines
-Bispecific T-cell engagers
PD-1 blockade antibody therapy is one of the cornerstone approaches in modern cancer immunotherapy.
Under normal physiological conditions, when PD-1 binds to its ligands (PD-L1 or PD-L2) on other cells, it functions as a "checkpoint" to reduce overly active T cell responses and prevent autoimmunity.
PD-1 blockade therapies involve monoclonal antibodies that target either PD-1 or its ligand PD-L1.
• By blocking the interaction between PD-1 and its ligands, these antibodies effectively release the "brakes" on T cells.
• The re-activated T cells can then recognize and destroy cancer cells more efficiently.

Immunotherapy Class Example Agents Primary Target Core Mechanism Interaction Considerations Net Effect
PD-1 inhibitors Nivolumab, Pembrolizumab PD-1 receptor on T cells Blocks inhibitory PD-1 signaling → restores cytotoxic T-cell activity High-dose steroids or strong immunosuppressants may blunt effect; autoimmune risk ↑ Anti-tumor immune activation
PD-L1 inhibitors Atezolizumab, Durvalumab PD-L1 on tumor/immune cells Prevents PD-L1 from engaging PD-1 → enhances T-cell response Similar immune-related adverse event (irAE) profile as PD-1 inhibitors ↑ Immune activation
CTLA-4 inhibitors Ipilimumab CTLA-4 checkpoint Enhances early T-cell priming in lymph nodes Higher autoimmune toxicity risk vs PD-1 class ↑ T-cell priming
CAR-T therapy CD19 CAR-T products Tumor antigen (e.g., CD19) Genetically engineered T cells directly target tumor cells Risk of cytokine release syndrome (CRS) and neurotoxicity Direct immune-mediated tumor killing
Monoclonal antibodies (non-checkpoint) Trastuzumab, Rituximab Specific tumor antigens Antibody-dependent cellular cytotoxicity (ADCC) or receptor blockade Combination with chemo common; immune activation depends on Fc engagement Targeted immune-mediated killing
Cytokine therapy IL-2, IFN-α Immune activation pathways Stimulates T-cell and NK cell proliferation High systemic toxicity; rarely used now vs checkpoint inhibitors Broad immune stimulation
Cancer vaccines mRNA or peptide-based Tumor antigens Induces tumor-specific immune memory Often combined with checkpoint blockade Adaptive immune priming
Bispecific T-cell engagers Blinatumomab CD3 + tumor antigen Bridges T cells directly to tumor cells CRS risk; continuous infusion in some protocols Direct T-cell redirection

Type:
PD-L1 is a protein that plays a crucial role in the regulation of the immune system. PD-L1 helps to prevent the immune system from attacking healthy cells by binding to its receptor, PD-1, on immune cells. However, some cancer cells can exploit this mechanism by expressing high levels of PD-L1, which can help them evade immune detection.
PD-L1 has become a key target for cancer immunotherapy, particularly in the development of checkpoint inhibitors.

PD-1: Upregulated on tumor-infiltrating lymphocytes (TILs), reflecting chronic antigen exposure and an “exhausted” T cell phenotype.
PD-L1 and PD-L2: Frequently overexpressed by many tumor types (e.g., non–small cell lung cancer, melanoma, renal cell carcinoma, head and neck cancers.
