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


STAT3, Signal transducer and activator of transcription 3: Click to Expand ⟱
Source:
Type: Oncogene
Stat3 (Signal Transducer and Activator of Transcription 3) is a transcription factor that plays a crucial role in various cellular processes, including cell growth, survival, differentiation, and immune response.
Stat3 is frequently found to be constitutively activated in many types of cancers, including breast, prostate, lung, and head and neck cancers. (associated with poor prognosis and reduced survival.)

-STAT3 is typically activated by cytokines (such as IL-6) and growth factors binding to their respective receptors.
-Activated STAT3 upregulates the expression of genes that promote cell cycle progression (e.g., cyclin D1) and anti-apoptotic proteins (e.g., Bcl-2, Bcl-xL).
