A worm's view on immunity

All higher organisms have an immune system that constitutes a biological defense mechanism to protect the body from pathogens and foreign substances. It consists of a complex network of different organs, cell types and molecules ...

How cGAS enzyme is kept bottled up

In higher organisms, detection of DNA in the cytoplasm triggers an immune reaction. The enzyme that senses "misplaced" DNA is also found in the nucleus, but nuclear DNA has no such effect. LMU researchers now report why that ...

Innate immune system

The innate immune system comprises the cells and mechanisms that defend the host from infection by other organisms, in a non-specific manner. This means that the cells of the innate system recognize and respond to pathogens in a generic way, but unlike the adaptive immune system, it does not confer long-lasting or protective immunity to the host. Innate immune systems provide immediate defense against infection, and are found in all classes of plant and animal life.
