Immunology
10 ideas, each explained on one page with a 60-second lesson you can play right there.
-
Antibody
An antibody is a specialized protein produced by immune cells to identify and latch onto foreign invaders like viruses and bacteria.
-
Antibody-dependent cellular cytotoxicity
Antibody-dependent cellular cytotoxicity uses antibodies to guide immune cells like natural killer cells to destroy infected or cancerous cells.
-
Antigen
An antigen is any molecule that can latch onto a specific immune receptor or antibody, acting like a chemical identifier.
-
CAR T cell
A CAR T cell is a patient's own white blood cell that has been genetically modified in a laboratory to hunt and destroy cancer cells.
-
Complement System
The complement system is a network of about 50 blood proteins that automatically attack foreign invaders and clear damaged cells.
-
Immune Memory
How specialized memory B and T cells recognize returning pathogens to eliminate them before they can cause illness.
-
Killer T Cells
Killer T cells are white blood cells that hunt and destroy infected or cancerous cells by recognizing antigens displayed on MHC molecules.
-
Major histocompatibility complex
Learn how the Major Histocompatibility Complex (MHC) presents protein fragments on cell surfaces to help T cells detect viruses and cancers.
-
Natural killer cell
Natural killer cells are white blood cells that destroy tumor and virus-infected cells lacking normal MHC class I identity markers.
-
T cell
Learn what T cells are, how they develop in the thymus, and how killer and helper T cells coordinate specific immune defenses.
