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

While we tend to quickly forget having been ill or having received a vaccine, the immune system remembers remarkably well. It has memory B cells—"trained" immune cells that circulate throughout the ...

Researchers from The University of Texas at Arlington and the University of California–San Francisco have used a new brain-mapping technique to identify memory-related brain cells vulnerable to ...

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 ...

The human brain contains roughly 86 billion neurons, and for decades scientists have assumed that these cells are the primary ...

We owe a lot to tissue resident memory T cells (T RM). These specialized immune cells are among the body's first responders to disease. Rather than coursing through the bloodstream-as many T cells ...

The brain may reuse some cells to store many different memories without mixing them up with or erasing older memories, a new study in mice suggests.

T lymphocytes differentiate from naïve precursors upon antigen encounter into distinct effector and memory subsets. Following priming by antigen-presenting cells in lymphoid tissues, naïve CD4+ and ...

For decades, dogma dictated that the immune system consisted of two separate branches. Cells of the innate system respond rapidly to molecular patterns shared by a broad array of pathogens. Meanwhile, ...

A new study uses optogenetics and roflumilast to prove sleep deprivation blocks memory retrieval, not storage.
