The Israeli study examined tumor samples and nearby lymph nodes from 11 patients with high-grade serous ovarian cancer.

A new Review reveals how aging can push the immune system into a paradoxical state, weaker against threats yet more prone to attacking the body’s own tissues.

Researchers have a new hypothesis for how brain cells called astrocytes might contribute to memory storage in the brain. Their model, known as dense associative memory, would help explain the brain's ...

The average human has about 1.8 trillion immune cells. These cells patrol the body for bacteria, viruses, cancers, and other threats. Vaccines enhance this security system by teaching our immune cells ...

However, details of the intervening steps, as researchers have learned in the past 65 years, are quite complex — certain cells carry the flu antigen to the immune system, specific immune cells respond ...

Antibody-mediated rejection (ABMR) remains the leading immunological cause of kidney allograft loss, yet its humoral origins are incompletely understood.

The human brain contains roughly 86 billion neurons, and for decades scientists have assumed that these cells are the primary drivers of memory and cognition. However, a new study from researchers at ...

Immune cells called B cells make antibodies that fight off invading bacteria, viruses and other foreign substances. During their preparation for this battle, B cells transiently revert to a more ...
