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

IL4, interleukin 4: Click to Expand ⟱

Type:

A cytokine that regulates humoral and adaptive immunity, and is involved in allergies and regulates inflammation.
IL-4 produced by cancer cells promotes resistance to immune checkpoint blockade (ICB). The close correlation between interleukin-4 (IL-4) and tumor progression has been observed in plenty of studies.

IL-4 is expressed in various cancers, including breast cancer, lung cancer, colorectal cancer, and hematological malignancies. Its expression can vary depending on the tumor type and the immune context.
Elevated levels of IL-4 are often associated with the presence of tumor-infiltrating immune cells, particularly Th2 cells and other immune cells that produce IL-4.
IL-4 is often considered a pro-tumorigenic cytokine. It can promote tumor growth and survival by enhancing the proliferation and survival of cancer cells. IL-4 can activate signaling pathways such as the STAT6 pathway, which is associated with cell proliferation and survival.
In some cancers, IL-4 can also promote angiogenesis, the formation of new blood vessels, which is critical for tumor growth and metastasis.
