Pathways transcriptionally dysregulated in MGUS- and MM- HDNs. Our work showed that MM-HDNs had increased expression of IL10RB, IFNGR1/2, TNFR1/2, TLR2, IL17RA/D. While IFN-gamma can activate IFNGR1/2 and IL10 can bind IL10RB in response to unresolved chronic inflammation, to activate STAT1 and STAT3 and promote their nuclear translocation, LPS triggers TLR2, through an adaptor complex which recruits TRAF6 to activate the TAK1 kinase complex can then activate the IKK complex leading to NFkB activation. The increased expression of TNFR1/B and component of their adaptor complex ½ can recruit several transcription factors to amplify the cascade and warrant a robust response. The genes target CD64 and ARG1 are under the transcriptional control of STAT1 and STAT3, as previously reported for other professional phagocytes. The lack of IL17RC excludes that the IL17R complex could be active, but the ligand of the overexpressed IL17RD is still unknown.
