MAST cells play a detrimental role in IgE dependent allergic reactions, In contrast, a protective function for mast cells has been proposed on the basis of some worm infection models. No reports exist on the in vivo significance of these cells in bacterial infections(1,2). Here we use congenitally mast-cell-deficient W/W-v mice and normal +/+ littermates(3,4) to analyse the role of mast cells in a model of acute septic peritonitis (caecum ligation and puncture (CLP)), Following CLP, W/W-v mice showed a significantly increased mortality compared to +/+ mice, The selective reconstitution of W/W-v mice with cultured +/+ mast cells substantially protected them from the lethal effects of CLP, whereas an anti-tumour-necrosis-factor (TNF) antibody injected immediately after CLP completely suppressed this protection, Our results reveal a previously unrecognized protective role of mast cells and mast-cell-derived TNF in acute bacterial peritonitis.
