Dashed arrows denote findings from previous studies; solid arrows denote observations from this work. Thickness of solid arrows indicates relative change in net flux compared to uninfected cells with thicker arrows being the favored direction of transport. Through use of GO annotation Figure 3 and analysis of relative gene expression patterns over time Figures 4 , 5 , our results reinforce and extend the contemporary model of HCMV maturation. Our model predicts that changes in the flux of ERC pathways lead to accumulation of transport machinery and associated cargo within discrete regions distributed throughout the cVAC.
This suggests a possible mechanism for the sequestration of immune signaling molecules as seen by others Hook et al. Based on the observed patterns and the requirement to maintain cellular homeostasis during the protracted HCMV replication cycle, we predict that this shift in the balance between endocytosis and exocytosis is offset by a corresponding increase in the net flux through SV-like pathways.
To this end, the model is consistent with previous observations that several SV trafficking proteins are associated with mature virions Homman-Loudiyi et al. Due to the highly conserved nature of these pathways across diverse cell types, our model encompasses mechanisms that may contribute to the wide cell tropism of HCMV.
It would be interesting to perform similar comparisons using the additional Merlin transcriptional and proteomic datasets from Tirosh et al. These included: a lack of supporting information regarding roles in trafficking events, the information contained in the databases is significantly behind current literature, and nomenclature differed depending on the field of study e.
The agreement between our results and their consistency with prior observations in spite of these limitations, suggests a deep biological imperative.
As is being done for other microbes, coordinated analyses of transcripts, proteins, protein modifications, and metabolic outcomes are needed. Such studies need to be conducted with multiple virus strains, in a variety of biologically relevant cell types, over a range of MOIs, and over a broad time course post-infection. In addition, ongoing investment is needed in updating and maintaining publicly accessible databases of host gene functions. Through studying the virus—host interactions occurring during the cytoplasmic stages of HCMV replication, we will also glean new knowledge of host cell biology.
It will ultimately become important to distinguish cellular systems that behave differently in the context of infection from systems that function in an unperturbed manner. The integrated roadmap presented here provides a foundation for interpreting experiments, past and present.

However, I have no way to know the URLs in advance and for that reason I cannot use any egress rules on this service. Describe alternatives you've considered I tried to disable egress rules on the deployment itself using the following annotation:. Is there a way to make it work? Is there a better alternative? Additional context I would like to keep istio ingress traffic for this microservice.
I've searched the repo for everything starting with sidecar.
Yes, I added the annotations to my deployment yaml configuration. Feel free to reopen the issue with more details about which type of error you get, your deployment spec and as much information as possible so that maybe it will help others. Thanks victorboissiere , can you plz reopen issue as I am unable to do so :.
So putting everything in detail here for better clarification. My service consist of following attributes in dedicated namespace Not using ServiceEntry. Now as stated in issues subject I want to allow all outgoing traffic for deployment because my serives needs to connect with 2 service discovery server:. Using following deployment file will not open outgoing connections. I have used almost all combinations in deployment but non of them seems to work.
Annotation Type ConnectorOperation
Anything I am missing or doing this in wrong way? I haven't found any proper documentation on all the labels available so I had to search in the github repository for some. I think I know where might be the issue. You are adding annotations on your deployment but not on your pods. I think Istio is just looking for annotations on pods.
