Susan Thomas discusses how her team engineered a microfluidic device to screen for T cells with improved homing capability to tumor cells. 

SARS-CoV-2 infection triggers structural changes in the host cell’s DNA, which provide a molecular explanation for long COVID, a new study suggests. 

The “tripledemic” shines a spotlight on viral interference, in which one infection can block another.

Scientists discover tumor-associated T cells that drive breast cancer metastasis to lymph nodes.

Immune cells deliver packages of telomeres to T cells, helping them retain their virus-fighting function over time, research suggests.

IgA antibodies appear to bind to specific species of commensal gut bacteria in mice, according to a study.

Several lines of evidence suggest that targeting the body’s defense pathways might help treat a subset of people with the psychiatric disorder. But many open questions remain.

Scientists have pinpointed several pathways through which the immune system could disrupt neuronal functioning and thereby lead to psychotic symptoms.

Two recent papers provide insight into possible risk factors for developing the chronic condition, including autoantibodies and diabetes.

Immunologists and parasitologists are working to revive the idea that helminths, and more specifically the molecules they secrete, could help treat allergies and autoimmune disease.

Research in animals and people supports a range of mechanisms by which the parasites affect physiology and immune responses.

Researchers report what appears to be the second case of a person’s immune system clearing the virus on its own.

Researchers find that the protective outer layer that lungfish make to survive extended dry periods—once thought to be a simple mucus shell—contains immune cells that trap bacteria and protect the animals from infection.
