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


XIAP, X-linked inhibitor of apoptosis protein (XIAP) baculoviral IAP repeat-containing protein 4 (BIRC4): Click to Expand ⟱
Source:
Type:
Also known as BIRC4. XIAP is inhibited by DIABLO (Smac) and HTRA2 (Omi), two death-signaling proteins released into the cytoplasm by the mitochondria.
High proportions of XIAP may function as a tumor marker. In developing prostate cancer, XIAP is one of four IAPs overexpressed in the prostatic epithelium.

XIAP functions predominantly as a protumorigenic protein in the context of cancer. Its upregulation is commonly observed in various tumor types and is associated with poor patient outcomes and resistance to therapy due to its potent inhibition of apoptosis.
