This lecture explores inflammation and stress signaling within the innate immune system, our first line of defense against pathogens. It delineates the rapid inflammatory responses that activate both innate and adaptive immune mechanisms, engaging various cellular players such as blood platelets, macrophages, mast cells, neutrophils, and endothelial cells. Key growth factors involved in these processes, including PDGF and VEGF, are also discussed, offering insights into cellular interactions that contribute to inflammation and immune responses.

Module 11: Inflamatory responses • Inflammatory responses • The innate immune system is our first line of defense against invading pathogens. • Initiates a vigorous and rapid inflammatory response to attack foreign pathogens • Plays a key role in activating the more slowly developing adaptive immune response. • Activation of specific B and T cells to extend the host defense system • Innate response is carried out by a complex series of cellular interactions, collectively known as the inflammatory response. • Cellular players in the innate immune response/inflamatory response are: • Blood platelets • Macrophages • Mast cells • Neutrophils • Endothelial cells Cell Signalling Biology - Michael J.
