The murine cytomegalovirus M45 protein interacts with receptor-interacting protein (RIP) 1 and RIP3 via a RIP homotypic interaction motif.
|
2 |
18442983
|
Thus, M45 is a viral inhibitor of RIP activation that provides a direct cell type-dependent replication benefit to the virus while modulating other biological processes signaling via the RIP1 adaptor such as activation of Toll-like receptor (TLR)3 as well as other mediators of cell death.

DNA-dependent activator of IFN regulatory factors (IRF; DAI, also known as ZBP1 or DLM-1) is a cytosolic DNA sensor that initiates IRF3 and NF-kappaB pathways leading to activation of type I IFNs (IFNalpha, IFNbeta) and other cytokines.
|
4 |
18941233
|
In this study, induction of NF-kappaB is shown to depend on the adaptor receptor-interacting protein kinase (RIP)1, acting via a RIP homotypic interaction motif (RHIM)-dependent interaction with DAI.
|
5 |
18941233
|
DAI binds to and colocalizes with endogenous RIP1 at characteristic cytoplasmic granules.
|
6 |
18941233
|
Suppression of RIP1 expression by RNAi abrogates NF-kappaB activation as well as IFNbeta induction by immunostimulatory DNA.
|
7 |
18941233
|
DAI also interacts with RIP3 and this interaction potentiates DAI-mediated activation of NF-kappaB, implicating RIP3 in regulating this RHIM-dependent pathway.
|
8 |
18941233
|
The role of DAI in activation of NF-kappaB in response to immunostimulatory DNA appears to be analogous to sensing of dsRNA by TLR3 in that both pathways involve RHIM-dependent signaling that is mediated via RIP1, reinforcing a central role for this adaptor in innate sensing of intracellular microbes.

Casp8 suppresses RIP3-RIP1 (also known as RIPK3-RIPK1) kinase complex-dependent necroptosis that follows death receptor activation as well as a RIP3-dependent, RIP1-independent necrotic pathway that has emerged as a host defence mechanism against murine cytomegalovirus.

Thus, Casp8 may naturally hold alternative RIP3-dependent death pathways in check in addition to promoting apoptosis.

Remarkably, Casp8(-/-)Rip3(-/-) double mutant mice are viable and mature into fertile adults with a full immune complement of myeloid and lymphoid cell types.

These compounds interact with RIP3 to activate caspase 8 (Casp8) via RHIM-driven recruitment of RIP1 (RIPK1) to assemble a Casp8-FADD-cFLIP complex completely independent of pronecrotic kinase activities and MLKL.

During infection, HSV modulates cell death pathways using the large subunit (R1) of ribonucleotide reductase (RR) to suppress apoptosis by binding to and blocking caspase-8.
|
160 |
25674983
|
Here, we demonstrate that HSV-1 and HSV-2 R1 proteins (ICP6 and ICP10, respectively) also prevent necroptosis in human cells by inhibiting the interaction between receptor-interacting protein kinase 1 (RIP1) and RIP3, a key step in tumor necrosis factor (TNF)-induced necroptosis.
|
161 |
25674983
|
We show that suppression of this cell death pathway requires an N-terminal RIP homotypic interaction motif (RHIM) within R1, acting in concert with the caspase-8-binding domain, which unleashes necroptosis independent of RHIM function.

We recently described the induction of noncanonical IL-1β processing via caspase-8 recruited to ripoptosome signaling platforms in myeloid leukocytes.
|
184 |
26100631
|
Here, we demonstrate that activated NLRP3·ASC inflammasomes recruit caspase-8 to drive IL-1β processing in murine bone marrow-derived dendritic cells (BMDC) independent of caspase-1 and -11.
|
185 |
26100631
|
Sustained stimulation (>2 h) of LPS-primed caspase-1-deficient (Casp1/11(-/-)) BMDC with the canonical NLRP3 inflammasome agonist nigericin results in release of bioactive IL-1β in conjunction with robust caspase-8 activation.
|
186 |
26100631
|
This IL-1β processing and caspase-8 activation do not proceed in Nlrp3(-/-) or Asc(-/-) BMDC and are suppressed by pharmacological inhibition of caspase-8, indicating that caspase-8 can act as a direct IL-1β-converting enzyme during NLRP3 inflammasome activation.
|
187 |
26100631
|
Biochemical analyses of WT and Casp1/11(-/-) BMDC indicated that caspase-8 is proteolytically processed within detergent-insoluble ASC-enriched protein complexes prior to extracellular export during nigericin treatment.
|
188 |
26100631
|
Although nigericin-stimulated caspase-1 activation and activity are only modestly attenuated in caspase-8-deficient (Casp8(-/-)Rip3(-/-)) BMDC, these cells do not exhibit the rapid loss of viability of WT cells.
|
189 |
26100631
|
These results support a contribution of caspase-8 to both IL-1β production and regulated death signaling via NLRP3 inflammasomes.
|
190 |
26100631
|
In the absence of caspase-1, NLRP3 inflammasomes directly utilize caspase-8 as both a pro-apoptotic initiator and major IL-1β-converting protease.
|
191 |
26100631
|
In the presence of caspase-1, caspase-8 acts as a positive modulator of the NLRP3-dependent caspase-1 signaling cascades that drive both IL-1β production and pyroptotic death.
