Let's Talk About Types
100

Coughing, sneezing, and blinking are considered as providing a type of barrier that is part of your innate immunity.

What is a mechanical barrier?

100
This type of immune response does not generate immunologic memory.

What is innate immunity?

100

This type of molecule plays a role in the inhibition of T-cell immune responses.  Common ligands are CTLA-4 and PD-L1.

What are checkpoint molecules?
100

This is the process by which the immune system identifies cancerous or precancerous cells and eliminates them before they become clinical.

What is immune surveillance?

100

The type of immunotherapy is administered prior to the growth of cancer to create memory of the immune system, giving the patient long-term immunity to a specific cancer.

What is a vaccine?

200

By eliminating dead or damaged cells and initiating tissue repair, the immune system plays a role in this body function.

What is homeostasis?

200

This type of immunity is characterized by the production of antibodies or immunoglobulins. Cells commonly associated with this type of immunity include plasma cells and B lymphocytes.

What is humoral immunity?

200

This protein found on T-cells has an inhibitory function that, when bound to its corresponding ligand, inhibits T-cell proliferation and cytotoxic function.  This protein has far-reaching implications in the treatment of many types of cancers.  

What is PD-1?

200

The 3 phases of this process include elimination, equilibrium, and escape.

What is immunoediting?

200

This type of immunotherapy is a lab-produced protein that is made to act like a human antibody. It may be made from murine proteins, human proteins, or somewhere in between.

What is a monoclonal antibody?

300

This is the main site for lymphocyte development and differentiation.

What is the bone marrow?

300

This type of immunity involves cytotoxic and helper T-cells.

What is cell-mediated immunity?

300

This enzyme is an important mediator of signaling cascades in cells. Its overexpression or mutation may lead to the formation of cancer. Common types include EGFR and BCR-ABL.

What is a tyrosine kinase?

300

This group of intracellular molecules are capable of being recognized by T-cells. Loss or alteration of this component allows a tumor to evade immune response.

What is major histocompatibility complex (MHC)?

300

This type of immunotherapy helps regulate T-cell function to make tumor cells visible to the patient’s immune system.

What are immune checkpoint inhibitors?

400

This is the body's first line of defense against pathogens.  It is essential to produce a nonspecific response to a pathogen or foreign substance.  

What is innate immunity?

400

This type of immune cell is cytotoxic to tumor cells and self-cells that are infected with a virus. They do not require a specific antigen to act.

What are natural killer (NK) cells?

400

This type of glycoprotein is produced in response to T-cell activation and itself is not generally considered cytotoxic. Common types of this protein are interleukins and interferon.

What is a cytokine?

400

During this phase, tumor cells are kept in check by the immune system but are not destroyed.

What is equilibrium?

400

This type of immunotherapy uses lab-modified living immune cells (often harvested from the patient) to trigger an immune response to a cancer cell. One example of this is CAR-T therapy.

What is adoptive cell transfer?

500

This begins when tumor antigens are recognized by antigen presenting cells (dendritic cells or macrophages) that present tumor antigens to the immune system, stimulating the priming and activation of appropriate immune cells. Activated immune cells are then directed to tumor sites, infiltrate the tumor, and kill cancer cells.

What is the cancer-immunity cycle?

500

Immune cells that are part of this line include multiple types of T-cells: helper, cytotoxic, memory, and regulator/suppressor cells.

What are lymphoid cells?

500

This signaling pathway has extracellular, transmembrane, and intracellular components. Mutations here result in unregulated cell growth in the absence of appropriate extracellular signals.

What is EGFR?

500

Tumor cells may fail to give off this type of signal that would normally elicit an immune response. This failure allows tumor cells to grow unchecked.

What is an inflammatory signal?

500

This type of immunotherapy produces a general immune response that activates a wide variety of immune cells. Drugs in this category include interferons and colony-stimulating factors.

What are cytokines?
