Intrinsic immunity refers to a set of cellular-based anti-viral defense mechanisms, notably genetically encoded proteins which specifically target eukaryotic retroviruses. Unlike adaptive and innate immunity effectors, intrinsic immune proteins are usually expressed at a constant level, allowing a viral infection to be halted quickly. Intrinsic ...
The immune system, particularly the innate component, plays a decisive role in tissue repair after an insult. Key actors include macrophages and neutrophils , but other cellular actors, including γδ T cells , innate lymphoid cells (ILCs), and regulatory T cells (Tregs), are also important.
The innate immune system or nonspecific immune system [1] is one of the two main immunity strategies in vertebrates (the other being the adaptive immune system). The innate immune system is an alternate defense strategy and is the dominant immune system response found in plants, fungi, prokaryotes, and invertebrates (see Beyond vertebrates). [2 ...
The following outline is provided as an overview of and topical guide to immunology: . Immunology – study of all aspects of the immune system in all organisms. [1] It deals with the physiological functioning of the immune system in states of both health and disease; malfunctions of the immune system in immunological disorders (autoimmune diseases, hypersensitivities, immune deficiency ...
A key difference between the two classes of diseases is that while AIDs trigger a malfunction of the innate immune system, autoimmune diseases trigger a malfunction of the adaptive immune system. [1] The boundaries between autoinflammation (overactivity of the innate immunity), autoimmunity (overactivity of the adaptive immunity) and ...
The major difference in the immune systems between plants and mammals is that plants lack an adaptive immune system, so plants can not determine which pathogens have attacked them before and thus easily mediate an effective immune response to them.
NK cells are the only lymphocytes considered part of the innate immune system (in contrast to the adaptive immune system. Yet they are much more closely related to T cells (part of the adaptive immune system) than to other cells of the innate immune system. NK cells not only share many surface markers, functions and activities in common with T ...
The cholinergic anti-inflammatory pathway provides a braking effect on the innate immune response which protects the body against the damage that can occur if a localized inflammatory response spreads beyond the local tissues, which results in toxicity or damage to the kidney, liver, lungs, and other organs.
