Immune System & Immune Response

1. Immune System & Immune Response

Passive Immunity: Definition & Examples

2. Passive Immunity: Definition & Examples

Learn all about passive immunity, including the different kinds and the various ways it is acquired and used. Then, check your new knowledge by taking a short quiz.

Acquired Immunity: T Cells, B Cells and Antibodies

3. Acquired Immunity: T Cells, B Cells and Antibodies

Have you ever wondered why some people don't ever seem to get sick? These people likely have an acquired immunity. Learn more about the immune system and how exposure to an illness one time can help your body to prevent that illness from ever occurring again.

What is an Antigen-Presenting Cell? - Definition & Types

4. What is an Antigen-Presenting Cell? - Definition & Types

Antigen-presenting cells (APCs) help start the body's immune response against infection by finding and activating T cells. This lesson will discuss how the APCs do this, and how the T cells respond.

Vaccination and Immunotherapy

5. Vaccination and Immunotherapy

This lesson will discuss the basics of how diseases can be prevented or treated using our own immune system's components. We'll talk about vaccination and immunotherapy as well as some specific examples, such as the BCG vaccine, monoclonal antibodies, and more.

HIV and AIDS: Mechanisms and Diseases of the Retroviridae Virus Family

6. HIV and AIDS: Mechanisms and Diseases of the Retroviridae Virus Family

Learn about one of the most famous viruses in the world: HIV. We'll also delve into a condition you've almost certainly heard of: AIDS. Finally, we'll discuss the mechanisms of how viruses in this family cause so much damage and if there's anything you can do about it.
