Lecture 3 Innate Immunity Pdf Innate Immune System Adaptive Trained immunity is a novel word in immunology; as we know, trained immunity refers to increased innate immune cell response. however, there is a process known as immunological tolerance that works in the opposite way as stimulants do to establish innate memory. Trained immunity is a functional state of the innate immune system that is characterized by long term epigenetic and metabolic reprogramming of cells associated with potent immune responses.
Trained Innate Immunity Trained Innate Immunity Represents Trained immunity is a long term functional modification of cells in the innate immune system which leads to an altered response to a second unrelated challenge. [1] for example, the bcg vaccine leads to a reduction in childhood mortality caused by unrelated infectious agents. [2]. Trained immunity is characterized by nonspecific increased responsiveness, mediated via extensive metabolic and epigenetic reprogramming. trained immunity explains the heterologous effects of vaccines, which result in increased protection against secondary infections. Here we define 'trained immunity' as a biological process and discuss the innate stimuli and the epigenetic and metabolic reprogramming events that shape the induction of trained immunity. Whereas the term ‘innate immune memory’ describes the epigenetically imprinted and recallable memory of inflammation, ‘trained innate immunity’ refers to the prepared and improved innate.

Trained immunity is a renewed concept of innate immune memory that facilitates the innate immune system to have the capacity to remember and train cells via metabolic and transcriptional events to enable them to provide nonspecific defense against. It has been demonstrated that trained innate immunity can be induced in many innate immune cell populations from both myeloid (monocytes macrophages, dendritic cells, neutrophils, and microglia) and lymphoid (natural killer cells, γδ t cells, and innate lymphoid cells) lineages. Immune memory is a defining feature of the acquired immune system, but activation of the innate immune system can also result in enhanced responsiveness to subsequent triggers. this process has been termed ‘trained immunity’, a de facto innate immune memory. Trained immunity is a functional state of the innate immune response and is characterized by long term epigenetic reprogramming of innate immune cells. this concept originated in the field of infectious diseases training of innate immune cells, such as monocytes, macrophages and or natural killer ….
