Gut cells sound the alarm when parasites invade

To effectively combat an infection, the body first has to sense it’s been invaded, then the affected tissue must send out signals to corral resources to fight the intruder. Knowing more about these early stages of pathogen recognition and response may provide scientists with crucial clues when it comes to preventing infections or treating inflammatory […]

Genetic engineering without unwanted side effects helps fight parasites — ScienceDaily

Around a third of the world’s population carries Toxoplasma gondii, a parasite that puts people with a weakened immune system at risk and can trigger malformations in the womb. The single-celled pathogen also leads to economic losses in agriculture, with toxoplasmosis increasing the risk of abortion among sheep, for example. The parasite has a complex […]

Malaria parasites adapt to survive the dry season — ScienceDaily

The main parasite that causes malaria can alter its gene expression to survive undetected in the human blood stream, new research has shown. A team of international researchers, including Dr Mario Recker from the University of Exeter, has studied how the parasite, Plasmodium falciparum, can lie seemingly dormant during unfavourable conditions. The study explains how […]

How malaria parasites hide from the human immune system

Malaria parasites survive tough times by not being too clingy. During Africa’s dry season, when mosquitoes are scarce, malaria parasites have a hard time spreading to new hosts. So the parasites hide out in the human body by keeping the cells they infect from clinging to blood vessels, researchers report October 26 in Nature Medicine. […]
