A category of antimicrobial peptides, cathelicidins and being researched by a team coordinated by Julien Diana, Inserm Research Fellow at Inserm Unit 1151 is focusing on. Apart from their protective function, these peptides have also exhibited immunoregulatory abilities against several autoimmune diseases.
They observed that beta pancreatic cells in non-diseased mice produce cathelicidins and that, interestingly, this production is impaired in diabetic mice...
