European Research Council supports search for regulators of tissue damage
Date:1/27/2012

There is more to fighting infection than just clearing the body of pathogens. As important as resisting infection, is limiting damage to the host's tissue caused, very frequently, by toxins produced by pathogens or by components of the host immune response that clears those pathogens. Indeed, it is the damage inflicted to different tissues and organs that, if uncontrolled, can lead to the lethal outcome of some infectious diseases.

The in-built capacity that an infected individual has to limit the extent of tissue damage caused by different pathogens, a phenomenon known as 'tolerance to infection', has fascinated Miguel Soares, a group Leader at the Instituto Gulbenkian de Cincia (IGC) in Portugal, for several years. Now, the European Research Council (ERC) has awarded his team an Advanced Grant of just over 2,2 million Euros, to investigate the mechanisms involved in this protective response. This line of research should identify and pave the way to the development of new therapeutic interventions, to quell the clinical outcome of various diseases.

Miguel Soares and his research team have already identified a restricted number of mechanisms, regulated by specific genetic programmes that control tissue damage in response to different types of infection. They have shown that these protective mechanisms are active for example against severe forms of malaria and severe sepsis. The researchers believe, however, that other protective mechanisms controlled by groups of so-called "protective genetic programmes" can act in a similar manner in the context of different diseases. Their aim is to identify these protective mechanisms, and describe how the genetic programs act, so that these may be targeted to treat a whole range of infectious diseases.

Says Miguel Soares, "Infectious diseases such as malaria and severe sepsis remain medical challenges today, acting as major killers across the globe. Our data suggest that one of the reasons for
