Eosinophils have recently been shown to participate in innate immune responses against mycobacteria. We have investigated whether Mycobacterium bovis BCG regulate the human eosinophil immune response. A negative correlation between mycobacteria internalization and eosinophil activation was observed. In addition, mannose-capped lipoarabinomannan from M. bovis BCG (ManLAM) failed to induce a significant release of eosinophil peroxidase and TNF-α. Noteworthy, ManLAM exhibited a potent inhibitory effect on eosinophil peroxidase release by TLR2-activated eosinophils involving the complement receptor-3 molecule and the phosphatidylinositol-3 kinase pathway. ManLAM, generally present in pathogenic mycobacteria, plays an important role in modulating eosinophil-dependent immune response.
