Antigens: The Structure, Function, And Immune Response

Explore the types, structure, and biological roles of antigens in the immune system

What you'll learn

Understand the basic definition and classification of antigens, including exogenous, endogenous, and autoantigens.

Learn about the structural and molecular features that influence antigen recognition by the immune system.

Explore antigen-antibody interactions and the factors that affect immune specificity and response.

Develop a foundational understanding of the role of antigens in immune function and biomedical research.

Requirements

Learners should have a high school-level understanding of biology, particularly in cell biology and basic immune system concepts, to follow the course materials effectively.

A general interest in biological sciences and curiosity about how the body defends itself from external agents will help maintain engagement throughout the course.

The ability to learn independently, review content, and revisit core concepts as needed is helpful for understanding immunological topics in greater depth.

A stable internet connection and access to a computer, tablet, or smartphone are necessary to view video lectures and access study materials without interruption.

Basic digital literacy, such as navigating online course platforms, accessing PDFs or videos, and participating in simple assessments, is expected for a smooth learning experience.

A willingness to take notes, pause and replay lectures, and self-assess understanding regularly will enhance knowledge retention and learning outcomes.

Description

The Antigens Online Course is a foundational program designed to introduce learners to the biological and functional aspects of antigens, key elements in the immune response. Antigens play a central role in how the body identifies and reacts to foreign substances, and this course aims to explain their structure, types, and interactions within the immune system in a clear and accessible way.Learners will explore the classification of antigens—including exogenous, endogenous, and autoantigens—along with the molecular characteristics that influence how antigens are recognized by immune cells. The course also examines antigen-antibody interactions, the concept of antigenicity and immunogenicity, and the role of antigens in the context of vaccines and laboratory diagnostics. While the course does not offer medical advice or make therapeutic claims, it provides scientific insights that can support further study or general interest in biology and health sciences.Throughout the modules, the focus remains on developing conceptual clarity and encouraging scientific curiosity. Animated visuals, case examples, and simple explanations help ensure that complex topics are introduced in a way that is engaging and suitable for a broad audience.Learners will explore the classification of antigens—including exogenous, endogenous, and autoantigens—along with the molecular characteristics that influence how antigens are recognized by immune cells.
