Human cell death captured for first time

Scientists based at the La Trobe Institute of Molecular Science have discovered that some molecules which are central to the body's defence and immune system are ejected from inside the decomposing cell to form long beaded ...

Plants detect bacterial endotoxin in similar process to mammals

Similar to humans and animals, plants possess an innate immune system that protects them from invading pathogens. Molecular structures that only occur in pathogens enable their recognition and trigger the immune response. ...

TLR9: Two rings to bind them?

University of Tokyo researchers have elucidated how Toll-like receptor 9 (TLR9) binds to pathogen DNA, activating the innate immune system. This discovery is vital for the design of new antiviral, antibacterial, allergy and ...

It slices, it dices, and it protects the body from harm

An essential weapon in the body's fight against infection has come into sharper view. Researchers at Princeton University have discovered the 3D structure of an enzyme that cuts to ribbons the genetic material of viruses ...

What makes a worm say 'yuck'

Researchers at Harvard-affiliated Massachusetts General Hospital (MGH) say they have uncovered a way that animals detect pathogens in their bodies that allows their systems to respond before cellular damage occurs.

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 ...
