New Delhi:

The working of our body to prevent infection from spreading in uncontrolled manner has been devised by researchers. This development may help in finding new ways to fight the harmful bacteria.

Fragments of thrombin - a common blood protein found in wounds - can aggregate both bacteria and their toxins but this was not found in normal blood plasma, according to the new study.

The aggregation takes place quickly in the wound. Due to this, not only bacteria and toxins gather but these are also “eaten” by the body’s inflammatory cells.

“Perhaps we do not need to kill them with antibiotics but simply gather them so that the body can better take care of the infection,” said Jitka Petrlova, Professor at Lund University in Sweden.

“This way, the body avoids the spread of the infection.  We believe this to be a fundamental mechanism for taking care of both bacteria and their toxins during wound healing,” said Petrlova, lead author of the study published in the journal Proceedings of the National Academy of Sciences (PNAS).

“Our discovery links aggregation and amyloid formation to our primary defence against infections - our innate immunity,” Petrlova said.

It is well known that various aggregating proteins can cause amyloid disease, in skin or internal organs, such as the brain.

Therefore, in order to protect us from infections a mechanism can sometimes be over-activated and lead to degenerative diseases, researchers said.

“I have always been fascinated by how nature has effectively created different defence mechanisms, and wound healing provides a rich source of new discoveries,” said Artur Schmidtchen, also a Professor at Lund University.

“The ability to effectively heal wounds is of evolutionary significance to our survival,” said Schmidtchen.

“Compared to antibiotics, innate immunity has been around for millions of years - and I think we should consider the application of these concepts in an era of increasing antibiotic resistance,” he said.
