Key Concepts

Innate Immunity

Innate immunity is the first line of defense against pathogens, providing rapid, non-specific responses using physical barriers, cellular responses, and various biochemical mechanisms to recognize and eliminate invaders.

Phagocytic Cells

Phagocytic cells, such as neutrophils and macrophages, are essential components of innate immunity. They ingest and destroy pathogens, contributing to early defense before the adaptive immune response is activated.

Fever

Fever is an innate immune response that raises body temperature with the goal of creating a less hospitable environment for pathogens and enhancing the efficiency of immune cell activities.

Histamines

Histamines are chemicals released by cells like mast cells during innate immune responses. They contribute to inflammation by increasing blood flow and vascular permeability at sites of infection or injury.

Cytokines

Cytokines are signaling molecules secreted during innate responses that help coordinate the immune response by promoting inflammation, recruiting immune cells, and alerting the adaptive immune system.

Inflammation

Inflammation is a central process in innate immunity characterized by redness, swelling, increased blood flow, and immune cell recruitment, all aimed at containing and eliminating pathogens.

Complement Activation

Complement activation involves a cascade of plasma proteins that enhance the ability of antibodies and phagocytic cells to clear microbes and damaged cells, playing a key role in innate immune defense.

Antigen-Presenting Cells

Antigen-presenting cells, such as dendritic cells and macrophages, are part of the innate immune system that capture antigens from pathogens and present them to T cells, thereby bridging the innate and adaptive immune responses.
