Upadacitinib is a medication widely used for the treatment of rheumatoid arthritis that works by inhibiting Janus kinase (JAK) enzymes, which are involved in signaling pathways that regulate immune responses. Now, scientists ...

The human immune system has specialized cells called CD4 cytotoxic T lymphocytes (CD4 CTLs), which have been shown to kill tumor cells in some cancers. When a person gets sick, these cells multiply in a process called clonal ...

The effects of global warming depend on species: The losers are legion, but a lucky few are winners. Now, researchers have shown that baleen whales are taking advantage of a newly opened-up fish bonanza in the Greenland Sea, ...

Researchers at Karolinska Institutet have discovered that gut bacteria can convert dietary nitrate and iron into protective molecules that may reduce the risk of cardiovascular and metabolic diseases. The study, published ...
