Having a robust enough immune system to live a longer life may come at the cost of chronic inflammation. Some immune cells undergo an inflammatory form of death that evolved to protect us from infections, but they also sometimes do this randomly, when no ...

Sharon Evans, a cancer immunologist at Roswell Park Comprehensive Cancer Center who studies the role of temperature in T cell responses, said that, to date, the influence of the external environment on immune function is understudied. However, researchers ...

A newly discovered type of immune cell found in fat tissue seems to contribute to the chronic inflammation associated with ageing, according to preliminary data from mice — but other immune cells in fat help to keep inflammation at bay 1. The ...
