NLRP3 cages revealed by full-length mouse NLRP3 structure control pathway activation
Andreeva L*, David L, Rawson S, Shen C, Pasricha T, Pelegrin P, Wu H.†. Cell 184, 1–16 (2021). PDF
"The NACHT-, leucine-rich-repeat- (LRR), and pyrin domain-containing protein 3 (NLRP3) is emerging to be a critical intracellular inflammasome sensor of membrane integrity and a highly important clinical target against chronic inflammation. Here, we report that an endogenous, stimulus-responsive form of full-length mouse NLRP3 is a 12- to 16-mer double-ring cage held together by LRR-LRR interactions with the pyrin domains shielded within the assembly to avoid premature activation.

Phase separation drives RNA virus-induced activation of the NLRP6 inflammasome
NLRP6 is important in host defense by inducing functional outcomes including inflammasome activation and interferon production. Here, we show that NLRP6 undergoes liquid-liquid phase separation (LLPS) upon interaction with double-stranded RNA (dsRNA) in vitro and in cells, and an intrinsically disordered poly-lysine sequence (K350-354) of NLRP6 is important for multivalent interactions, phase separation, Read More
Dipeptidyl peptidase 9 sets a threshold for CARD8 inflammasome formation by sequestering its active C-terminal fragment
Sharif H*, Hollingsworth LR*, Griswold AR*, Hsiao JC, Wang Q, Bachovchin DA†., Wu H† Immunity 54: 1-13 (2021). PDF
Inflammasomes are multiprotein complexes that execute pyroptosis in response to cytosolic danger signals. DPP9 regulates the CARD8 inflammasome by unknown mechanisms. Here, Sharif et al. report cryo-EM structures of CARD8 bound to DPP9 and show that this complex inhibits CARD8 inflammasome activation downstream of the proteasome. Read More
Gasdermin D pore structure reveals preferential release of mature interleukin-1
Xia S, Zhang Z, Magupalli VG, Pablo JL, Dong Y, Vora SM, Wang L, Fu T-M, Jacobson MP, Greka A, Lieberman J, Ruan J†,, Wu H†. Nature 593: 607-611 (2021) PDF
As organelles of the innate immune system, inflammasomes activate caspase-1 and other inflammatory caspases that cleave gasdermin D (GSDMD). Caspase-1 also cleaves inactive precursors of the interleukin (IL)-1 family to generate mature cytokines such as IL-1β and IL-18. Cleaved GSDMD forms transmembrane pores to enable the release of IL-1 and to drive cell lysis through pyroptosis. Here we report cryo-electron microscopy structures of the pore and the prepore of GSDMD. Read More
DPP9 sequesters the C terminus of NLRP1 to repress inflammasome activation
Hollingsworth, L.R.*, Sharif, H.*, Griswold, A.R.*, Fontana P., Mintseris J., Dagbay K.B., Paulo J.A., Gygi S.P., Bachovchin D.A.†, Wu H.† DPP9 sequesters the C terminus of NLRP1 to repress inflammasome activation. Nature 592, 778–783 (2021). PDF
Nucleotide-binding domain and leucine-rich repeat pyrin-domain containing protein 1 (NLRP1) is an inflammasome sensor that mediates the activation of caspase-1 to induce cytokine maturation and pyroptosis. Gain-of-function mutations of NLRP1 cause severe inflammatory diseases of the skin. NLRP1 contains a function-to-find domain that auto-proteolyses into noncovalently associated subdomains, and proteasomal degradation of the repressive N-terminal fragment of NLRP1 releases its inflammatory C-terminal fragment (NLRP1 CT).

Mechanism of filament formation in UPA-promoted CARD8 and NLRP1 inflammasomes
Hollingsworth LR*., David L*., Li Y*., Griswold AR., Ruan J., Sharif H., Fontana P., Orth-He EL., Fu, T., Bachovchin DA, Wu H.† Mechanism of filament formation in UPA-promoted CARD8 and NLRP1 inflammasomes. Nat Commun 12, 189 (2021). PDF
NLRP1 and CARD8 are related cytosolic sensors that upon activation form supramolecular signalling complexes known as canonical inflammasomes, resulting in caspase-1 activation, cytokine maturation and/or pyroptotic cell death. NLRP1 and CARD8 use their C-terminal (CT) fragments containing a caspase recruitment domain (CARD) and the UPA (conserved in UNC5, PIDD, and ankyrins) subdomain for... Read More
