Bacteria can 'outsmart' programmed cell death

Certain bacteria can override a defence mechanism of the immune system, so called programmed cell death, through inhibition of death effector molecules by their outer membranes components. Shigella bacteria, which cause diarrhoea, ...

How influenza virus evades the body's immune response

Researchers at the University of Southern California (USC) have identified a critical molecular mechanism that allows the influenza virus to evade the body's immune response system.

Imaging algorithm gathers information about how cells move

Brown University engineers have developed a new technique to help researchers understand how cells move through complex tissues in the body. They hope the tool will be useful in understanding all kinds of cell movements, ...

Researchers find genes that help frogs resist fungus

(PhysOrg.com) -- For several decades, the fungal pathogen Batrachochytrium dendrobatidis (Bd) has been decimating frogs, yet some populations and species have been able to resist the fatal disease, called chytridiomycosis.

Get touchy feely with plants

Forget talking to plants to help them grow, gently rubbing them with your fingers can make them less susceptible to disease, a paper in the open access journal BMC Plant Biology reveals.

How plants shut the door on infection

Plants have a unique ability to safeguard themselves against pathogens by closing their pores—but until now, no one knew quite how they did it. Scientists have known that a flood of calcium into the cells surrounding the ...
