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


CXCc, CXC chemokine family: Click to Expand ⟱
Source: HalifaxProj(inhibit)
Type:
(Prev called GRO1 oncogene)(KC) belongs to the CXC
The chemokine ligand 1 (CXCK1) is a small peptide belonging to the CXC chemokine family that acts as a chemoattractant for several immune cells, especially neutrophils or other non-hematopoietic cells to the site of injury or infection and plays an important role in regulation of immune and inflammatory responses.
CXCL1 is increased in ovarian cancer via GRB2-associated binding protein 2-dependent autocrine way, promoting tumour cells proliferation and angiogenesis;
Keratinocyte-derived chemokine (KC) belongs to the CXC family and it is homologous to interleukin (IL)-8.
The CXC chemokines can be further divided into two main subgroups based on the presence or absence of the ELR (Glu-Leu-Arg) motif:
1. ELR+ CXC Chemokines: These include chemokines such as CXCL1, CXCL2, CXCL3, CXCL5, CXCL6, CXCL7, CXCL8 (IL-8), and CXCL12 (SDF-1). They are primarily involved in promoting angiogenesis, recruiting neutrophils, and facilitating tumor growth.
2. ELR- CXC Chemokines: This subgroup includes chemokines like CXCL4, CXCL9, CXCL10, and CXCL11. These chemokines are often associated with anti-tumor immunity and can attract T cells and other immune cells to the tumor microenvironment.
CXC chemokines, particularly the ELR+ subset, can promote tumor growth by enhancing angiogenesis. CXC chemokines are involved in the metastatic spread of cancer cells. For example, CXCL12 and its receptor CXCR4 are known to play significant roles in the migration of cancer cells to distant sites, such as the bone marrow and lymph nodes.
Given their roles in cancer progression, CXC chemokines and their receptors are being investigated as potential therapeutic targets.
