Immune Response Complexity

The immune response consists of distinct components: humoral immunity (antibody-mediated) and cell-mediated immunity (T-cell response).
Adaptive immunity has several phases, including recognition, activation, and effector phases.

Human Vaccination Milestone

In 1885, Louis Pasteur successfully vaccinated Joseph Meister against rabies, establishing a significant advancement in disease prevention.

Immune System Function

The primary role of the immune system is to differentiate between self (the body's own cells) and non-self (foreign invaders).
Immune mechanisms involve attacking and eliminating microbial threats while avoiding damage to self-cells.

Pathogen Types

The immune system targets two main categories of pathogens:
- Extracellular organisms: bacteria, fungi, parasites.
- Intracellular pathogens: primarily viruses.

Inflammation

Inflammation is a crucial response in the immune system, aiding in the recruitment of immune cells to sites of infection or injury.

Innate Immune Mechanisms

Innate immunity lacks memory, making it a first-line defense mechanism.
Innate immune receptors play a key role in recognizing pathogens and initiating responses.
The innate immune response involves the release of cytokines, which are signaling molecules that modulate immune responses.

Immune Dysfunction

Immune dysfunction occurs in various forms and will be explored in more detail later in the course.

Test your knowledge on the immune response, focusing on the distinctions between humoral and cell-mediated immunity. This quiz explores the complexities of adaptive immunity and its phases, ensuring a deeper understanding of the immune system.
