PPARG and infection: Interestingly, even infection with dead bacteria triggers PPARγ expression, as paraformaldehyde-killed M. tuberculosis or cell-wall components; mostly mannose-caped lipoarabinomannan (ManLAM) from either BCG or M. tuberculosis, are able to induce PPARγ expression, suggesting the role of pattern recognition receptors in the regulation of PPARγ [14–16].
