New immune defenders added to blood cell

Our researchers have revealed the identities of new subsets of immune cells at the frontline of our body’s defenses against infection. The research team’s discovery expands the understanding of immune cells called granulocytes – immune cells that can trigger inflammation and engulf microbes to slow an infection’s progress. As well as protecting against infection, granulocytes

Malaria: Cooperating antibodies enhance immune response

Malaria is one of the most infectious diseases worldwide. Scientists from the German Cancer Research Center (DKFZ) in Heidelberg, Germany, and from the Hospital for Sick Children (SickKids) in Toronto, Canada, have studied how the human immune system combats malaria infections. In this study, the researchers discovered a previously unnoticed characteristic of antibodies against the

Two-pronged antibodies draw immune killers directly to cancer cells

Our immune system’s arsenal of defenses usually protects us from cancer. But sometimes, cancer cells overwhelm or evade this elaborate defense system. In the lab of biochemist and immunologist Christoph Rader, Ph.D., associate professor at The Scripps Research Institute in Florida, scientists have engineered a new type of anti-cancer antibody, one intended to enhance nature’s

When your immune system meddles in your love life

About a decade ago, evolutionary psychologists suggested that humans have evolved a first line of defense against disease: a behavioural immune system (BIS). This system is thought to be unconsciously activated, to varying degrees, when an individual perceives, rightly or wrongly, that there is a threat of disease. Although we cannot see microorganisms with our

Fetal immune system rejects the mother in preterm labor

Preterm labor, a common pregnancy complication, has long been a mystery to scientists. But a new study from UC San Francisco shows it may sometimes happen when the fetal immune system “wakes up” too early and begins to reject the mother, causing the uterus to start contracting. The researchers think the fetal immune system becomes
