A unique quality of the immune system is that it can generate a ‘memory’ response. This is generally referred to as ‘immune memory’ because of the body’s ability to remember previously encountered ...

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 ...

Memory T cells are a special type of white blood cell that "remember" past infections and vaccines, helping our bodies to quickly respond if we encounter the same germs again. These cells are found ...

A macrophage that has already fought off one infection does not return to a blank slate. It carries chemical scars, etched ...

A new AI-based method reconstructs spatial information about where immune cells were originally located in an organ, even after these cells have been removed from the tissue and analyzed individually.

The research group of prof. Sanjiv Luther at the department of immunobiology of the University of Lausanne has discovered ...

Scientists analyzing human and mouse pancreatic lymph nodes (PLNs) and spleens have identified a distinct subset of CD4 memory helper T cells associated with type 1 diabetes (T1D). Reported by ...

Our new findings suggest that these changes in macrophages are actually readily reversible and do not inherently encode immune memory. Instead, the cells are dependent on ongoing signaling from ...

Researchers have discovered that the immune system's T cells can travel to the prostate to provide long-term protection against infections. Their findings suggest we might harness these same ...
