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


MAPK, mitogen-activated protein kinase: Click to Expand ⟱
Source: CGL-CS
Type:
Mitogen-activated protein kinases (MAPKs) are a group of proteins involved in transmitting signals from the cell surface to the nucleus, playing a crucial role in various cellular processes, including growth, differentiation, and apoptosis (programmed cell death).

MAPK Pathways: The MAPK family includes several pathways, the most notable being:
1.ERK (Extracellular signal-Regulated Kinase): Often associated with cell proliferation and survival.
2.JNK (c-Jun N-terminal Kinase): Typically involved in stress responses and apoptosis.
3.p38 MAPK: Associated with inflammatory responses and apoptosis.

Inhibitors: Targeting the MAPK pathway has become a strategy in cancer therapy. For example, BRAF inhibitors (like vemurafenib) are used in treating melanoma with BRAF mutations.
Altered Expression Levels:
Overexpression: Many cancers exhibit overexpression of MAPK pathway components, such as RAS, BRAF, and MEK. This overexpression can lead to increased signaling activity, promoting cell proliferation and survival.
Downregulation: In some cases, negative regulators of the MAPK pathway (e.g., MAPK phosphatases) may be downregulated, leading to enhanced MAPK signaling.
The expression levels of MAPK pathway components can serve as biomarkers for cancer diagnosis, prognosis, and treatment response. For example, high levels of phosphorylated ERK (p-ERK) may indicate active MAPK signaling and poor prognosis in certain cancers.

Numerous reports indicate that the MAPK pathway plays a major role in tumor progression and invasion, while inhibition of MAPK signaling reduces invasion.
