Key Concepts

Innate Immune Response

The innate immune response is the body's first line of defense against pathogens, characterized by non-specific, rapid responses that do not require prior exposure to a pathogen. It includes mechanisms like physical barriers, phagocytic cells, inflammation, fever, complement activation, cytokine release, and histamine-induced vascular changes.

Adaptive Immune Response

The adaptive immune response is a later-developing, highly specific defense mechanism that is activated after innate immunity. It involves the recognition of specific antigens, the proliferation of lymphocytes, and the formation of immunological memory, allowing for a more effective and targeted response upon subsequent exposures.

Antigen Presentation

Antigen presentation is the process by which cells, known as antigen-presenting cells, process and display fragments of pathogens (antigens) on their surface, usually via MHC molecules, to T cells. This process is crucial for the activation of the adaptive immune response and is not considered a part of the innate immune system, even though some cells of the innate system partake in it to initiate adaptive responses.

Phagocytic Cells

Phagocytic cells, such as macrophages and neutrophils, are a component of the innate immune response. They engulf and destroy pathogens, playing an essential role in the early, non-specific defense against infections.
