A new study shows human immune systems differ across populations, raising new questions for medicine and global drug research ...

The immune system’s first encounter with a virus or vaccine establishes a “starting template” that shapes its response to new ...

Scientists generally agree that eukaryotes, the domain of life whose cells contain nuclei and that includes almost all multicellular organisms, originated from a process involving the symbiotic union ...

Inflammatory gut bacteria that carry proteins structurally similar to myelin may trigger the development and progression of ...

Researchers found a molecular mechanism, shared in cancer and pregnancy, that suppresses the immune system. Block this mechanism, called B7-H4, and the immune system revs up to slow cancer's growth.

Researchers at MIT have unveiled a way to temporarily reboot aging immune systems, using a targeted mRNA therapy that turns the liver into a short‑lived factory for powerful T‑cell survival signals.
