Deep in our cells, a wide range of processes are occurring constantly. These cellular processes rely on enzymes to act as catalysts and set off a series of molecular interactions. There are still many ...

CAMBRIDGE, MA -- By stimulating cancer cells to produce a molecule that activates a signaling pathway in nearby immune cells, MIT researchers have found a way to force tumors to trigger their own ...

They found a suite of proteins used by the immune system to attack pathogens. The process is often called the granzyme-perforin pathway. Immune cells such as killer T cells or natural killer cells ...

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 ...

Ten years of substantial work by Université de Montréal immunologist Nathalie Labrecque's team at the Montreal Clinical Research Institute (IRCM) and the Maisonneuve-Rosemont Hospital Research Center ...

In this study, scientists looked at joint tissue biopsies from patients in the early stages of RA. They found a suite of proteins used by the immune system to attack pathogens. The process is often ...
