Supplementary Fig. 1

ESAT-6-dependent effects on RAW264.7 macrophages are not due to IL-10 induction and ESAT-6 does not modulate TLR ligand-dependent TLR-MyD88 interactions.

Supplementary Fig. 2

ESAT-6 inhibits the interaction of MyD88 with IRAK-4.

Supplementary Fig. 3

ESAT-6 does not induce MyD88s or IRAK-M, nor does it alter expression of TLRs and negative regulators of TLR signaling.

Supplementary Fig. 4

ESAT-6-mediated attenuation of IL-12 p40 release does not require TLR1, TLR6 or CD14 and ESAT-6 attenuates TLR ligand-induced IRAK-4 kinase activity in a PI-3K/Akt-dependent manner.

Supplementary Fig. 5

ESAT-6 interacts directely with the extracellular domain (ECD) of TLR2.

Supplementary Fig. 6

ESAT-6 inhibits TLR ligand-induced activation of IKKbeta kinase activity, LPS-driven activation of p38 MAPK and nuclear translocation of IRF-3 in RAW cells.

Supplementary Fig. 7

The C terminus of ESAT-6 inhibits TLR ligand induced nuclear translocation of IRFs 5, 1 and 3, binds to the surface of RAW cells and inhibits TLR ligand-induced IL12p40 production in bone marrow derived macrophages (BMDMs).

Sequences of overlapping peptides of ESAT-6.
