Summary
New cancer immunotherapies targeting programmed death-1 (PD-1) and programmed death-ligand 1 (PD-L1) show high activity and potential for durable responses in various cancers. Biomarkers like tumor PD-L1 expression may help identify patients who will benefit most.
Area of Science:
- Oncology
- Immunology
- Cancer Research
Background:
- T-cell-based cancer immunotherapy aims for lasting patient benefit.
- Previous therapies had limited efficacy, high toxicity, and lacked predictive biomarkers.
- Emerging programmed death-1 (PD-1) and programmed death-ligand 1 (PD-L1) inhibitors show promise.
Purpose of the Study:
- To evaluate the activity and potential of PD-1/PD-L1 inhibitors in cancer treatment.
- To explore the role of PD-L1 expression as a biomarker for patient selection.
- To understand the interaction between the immune system and cancer.
Main Methods:
- Review of preclinical data.
- Analysis of early clinical study results.
- Investigation of correlations between tumor PD-L1 expression and treatment response.
Main Results:
- PD-1 and PD-L1 inhibitors demonstrate significant activity across various tumor types, including lung and colon cancer.
- Durable clinical responses are observed in patients treated with these inhibitors.
- Tumor PD-L1 expression shows potential as a predictive biomarker.
Conclusions:
- Targeting the PD-1/PD-L1 pathway offers a promising new avenue for cancer therapy.
- Biomarker-guided selection of patients can optimize treatment outcomes.
- These findings advance our understanding of cancer immunology and host-pathogen interactions.

01:31The Intrinsic Apoptotic Pathway
Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
01:17The Extrinsic Apoptotic Pathway
The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...
01:27Cytotoxic T Cells-mediated Immune Response
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

01:19Interactions Between Signaling Pathways
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

01:27Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
01:28Cells of the Innate Immune Response
The innate immune response is an immediate and non-specific response against pathogens, acting swiftly to prevent the spread of infections. The primary cells involved in this response are phagocytes and natural killer (NK) cells.
Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...
