The innate immune system
The innate immune system ; is an important subsystem of the overall immune response system that comprises the cells and mechanisms that defend the host from infection by other organisms. The cells of the innate system recognize and respond to pathogens in a generic way, but, unlike the adaptive immune system, the system does not confer long-lasting or protective immunity to the host. Innate imm...
متن کاملModelling the Innate Immune System
The Human Immune System (HIS) is a complex network composed of specialized cells, tissues, and organs that is responsible for protecting the organism against diseases caused by distinct pathogenic agents, such as viruses, bacteria and other parasites. The first line of defence against pathogenic agents consists of physical barriers of skin and the mucous membranes. If the pathogenic agents brea...
متن کاملInnate Immune System and Preeclampsia
Normal pregnancy is considered as a Th2 type immunological state that favors an immune-tolerance environment in order to prevent fetal rejection. Preeclampsia (PE) has been classically described as a Th1/Th2 imbalance; however, the Th1/Th2 paradigm has proven insufficient to fully explain the functional and molecular changes observed during normal/pathological pregnancies. Recent studies have e...
متن کاملThe Innate Immune System in Alzheimer's Disease
Alzheimer's disease (AD) is the leading cause for dementia in the world. It is characterized by two biochemically distinct types of protein aggregates: amyloid β (A β ) peptide in the forms of parenchymal amyloid plaques and congophilic amyloid angiopathy (CAA) and aggregated tau protein in the form of intraneuronal neurofibrillary tangles (NFT). Several risk factors have been discovered that a...
متن کاملSignaling Organelles of the Innate Immune System
There are at least five families of microbe-detection receptors that function to detect and eradicate potentially infectious microorganisms that enter multicellular eukaryotes. While a multitude of proteins regulating innate immune signal transduction have already been defined, continuous genetic screening for regulators of innate immunity may not yield as significant insight into the operation...
