A B-cell receptor critical for the production of a subset of intestinal antibodies has been pinpointed, but the function of those antibodies remains unclear.

In most vertebrates, the absence of adaptive immunity would be catastrophic, but in some deep-sea angler fish species, it enables their “wild” and “wacky” mating habits.

Scientists are examining the role of T cells, which are likely crucial for long-term protection against SARS-CoV-2.

Cancer therapies could potentially be more effective if their development took into account the cells that give rise to tumor-fighting cells.

Meet some of the people featured in the July/August 2020 issue of The Scientist.

Better understanding the CD8+ T cells already present in tumors could be key to making immunotherapies work for more patients.

A small subset of uninfected people also had SARS-CoV-2-fighting T cells, a finding that scientists are still trying to figure out.

While the finding doesn’t prove people become immune to the virus after infection, it is good news for vaccine development.

Studies are underway to test whether giving a shot of BCG vaccine could protect doctors and nurses against COVID-19.
