The complex of defensive strategies characterizing invertebrate immune systems and response is reviewed. These include the role of pathogen recognition molecules and evolutionary aspects concerning a number of molecular components. Effective humoral resp
Adaptive (Acquired) Immune Response - 3rd line of defense Depends on B and T lymphocytes - specific immune response directed attack against pathogens (antigen) Lag time ~ two weeks, previous Antigen exposure required Protects against pathogens and cancer cells Two Components: Antibody-mediated...
Human Immune System honours T cells act in one of four processes: as helper T cells which recognise antigens, and stimulate the production of B cells as killer T cells which attack cells containing a foreign antigen, as suppressor T cells which stop immune responses as memory T cells which ...

Neutrophils are a major component of the innate immune system and, as the most numerous cell type of circulating leukocytes, are the host's first line of defense against invading bacteria and other pathogens [28]. Therefore, further analyses were performed on neutrophils. Neutrophils were divided ...
The immune system remains the first line of defense against disease causing microorganisms and other noxious substances. It is a multifaceted system of cells and proteins that protect the body against infections. There are many factors influencing an individual being healthy or becoming sick based on...
persistent impairment of the cellular or humoral components of the immune system, caused by extrinsic factors such as infectious agents, drugs, metabolic disorders, and environmental conditions that affect a host with an intrinsically normal immune system, leading to increased risk of infection [1–3...
indicating a complex interplay between the peripheral immune and the central nervous system. While the significance of different immune cell subtypes in the development of secondary neurodegeneration has been well established in adult brain injury, e.g. in the context of ischaemic stroke45, this resea...
