Scientists studying the body's cancer-fighting T cells have a serious problem: When they culture them in the lab, the T cells sit around at equilibrium, waiting to bump into cancerous cells. But that's not how they operate ...
Most living cells have a defined number of chromosomes: Human cells, for example, have 23 pairs. As cells divide, they can make errors that lead to a gain or loss of chromosomes, which is usually very harmful.
IBM announced its researchers have identified a new way to trigger the body's immune response by using polymer-coated graphene sheets. The research was recently published in Nature Communications.
The richest and poorest Americans differ in life expectancy by more than a decade. Glaring health inequalities across the socioeconomic spectrum are often attributed to access to medical care and differences in habits such ...
There's no getting around it. A lot of scientists are white men, and it's always been that way.
Toxoplasma gondii is a common parasite which causes the development of fatal encephalosis or pneumonia in immunodeficient patients under treatment of AIDS or cancer. Pregnant women who are infected may suffer a miscarriage ...
The immune system is a complex network of many different cells working together to defend against invaders. Successfully fighting off an infection depends on the interactions between these cells.
Researchers in Bern, Germany, have discovered that, during a viral infection, immune cells control the blood stem cells in the bone marrow and therefore also the body's own defences. The findings could allow for new forms ...
Mammals contain cells whose primary function is to kill other cells in the body. The so-called Natural Killer (NK) cells are highly important in defending our bodies against viruses or even cancer. Scientists at the University ...
Fighting viruses is a regular battle for your body, one it routinely wins if it has a healthy immune system. But compromised systems, as experienced occasionally by astronauts during space flights, can allow viruses to return.
