T cells are some of the immune system's most important warriors. They can stop tumor growth and even fight off severe ...

Scientists investigating how influenza viruses replicate within cells "accidentally" discovered that different flu viruses ...

In evolutionary biology, all life on Earth is theoretically part of a single phylogenetic tree, indicating common ancestry.

When a pathogen like a dangerous virus invades the human body, it usually has to enter human cells to cause an illness. Influenza has to latch onto a receptor on the surface of a human cell so it can ...

When viruses invade a plant, you might expect an all-out immune war. But new research published in Science shows that, much like in humans, too strong an immune response can actually do more harm than ...

Progressive multifocal leukoencephalopathy (PML) is a rare but serious brain infection. It gradually destroys brain tissue and often leads to death within a few weeks. It is triggered by human ...

A new study reveals the biological secret to the Zika virus's infectious success: Zika uses host cells' own 'self-care' system of clearing away useless molecules to suppress the host proteins that the ...

CAR T cell therapy is one of the most promising new cancer treatments to emerge in recent years. It involves removing a patient's own immune T cells and engineering them to recognize specific targets ...

Furtivovirus takes an in-between tactic. After infecting a cell, it breaks down the cell's nucleus, coopting the cell's ...

Although bioprocessors employ cell cultures to develop new treatments for viral infections, viral contamination can stymy any cell culture-based process, including the development of most any ...
