A surface molecule found on viruses or bacteria A disease-causing organism or virus A protein that attacks a specific antigen to help fight disease Mission: Level 2 What is an antibody? A surface molecule on a pathogen that allows the immune system to recognize the pathogen A disease-causing organism or virus A protein that attacks a specific antigen to help fight disease A white blood cell that helps fight off disease Mission: Level 3 (No Multiple Choice questions) Bonus Level! Hint: Click on a Plasma B cell to use it. When finished, change B cells by clicking a different one. Antibodies are specific. What does this mean? An antibody will only attach to a particular antigen, but will not attach to others. Antibodies only work against a particular pathogen, but will not help fight against other, unrelated pathogens. An antibody that fights against influenza will not work against the bacteria that cause strep throat. All of the above statements are true about antibody specificity. Mission: Level 4 What do macrophages do? They ingest pathogens by endocytosis and display the pathogen’s antigens on their surface to help activate the immune response. They interact with displayed antigens to help activate other lymphocytes (white blood cells) involved in the immune response. They produce antibodies that make pathogens floating in the blood or other body fluids for destruction. This helps prevent them from spreading. They destroy that have been infected by pathogens. What do helper T cells do? They ingest pathogens by endocytosis and display the pathogen’s antigens on their surface to help activate the immune response. They interact with displayed antigens to help activate other lymphocytes (white blood cells) involved in the immune response. They produce antibodies that make pathogens floating in the blood or other body fluids for destruction. This helps prevent them from spreading.
