In 1901, Paul Ehrlich conducted one of the landmark experiments in immunology. While studying the immune response in goats using blood from other animals, ...

Multicellular organisms are a mosaic of different cells, tissues, and systems, each with their own specific function and interactions with other cells within the organism and/or the larger environment ...

Normally, the immune system recognizes and eliminates abnormal cells. However, cancer cells can develop strategies to evade ...

A single signaling pathway controls whether immune cells attack or befriend cells they encounter while patrolling our bodies, ...

When the immune system overreacts and starts attacking the body, the only option may be to shut the entire system down and risk developing infections or cancer. Immune cells that are designed to ...

Borrowing a cancer cell’s disguise, scientists shielded insulin-producing cells from attack by the immune system, a breakthrough that could pave the way for targeted type 1 diabetes treatments without ...

Immunotherapy, which uses programmed immune cells to selectively destroy cancer cells, has transformed cancer treatment. However, cancer cells have developed immune evasion strategies, leading to poor ...

It is comparatively easy to tell a cell's state of health: On their surface, cells present fragments of almost all the proteins they contain inside. This means the immune system can directly recognize ...

One of the main changes is a loss of the innate immune system's naive T cells, the first line of defense against pathogens, and an increase in the adaptive immune system's memory T cells. This ...

Researchers at MIT and Stanford University have developed a new way to stimulate the immune system to attack tumor cells, using a strategy that could make cancer immunotherapy work for many more ...

A decade ago, a clinical trial in the U.K. famously showed that children who were exposed to peanuts in the early months of life had reduced risk of developing a peanut allergy compared with children ...

Over time, clonal expansion leads to an increase in the frequency of infected cells in a patient. The proviruses in daughter ...
