Systematic comparison of strategies for the enrichment of lysosomes by data independent acquisition

ABSTRACT: We describe a comparison of individual approaches for the enrichment of lysosomes comparing four different strategies using data independent acquisition (DIA). As a benchmark, we chose a crude enrichment strategy, which is the centrifugation of the PNS at 20,000 x g termed organelle enriched pellet (OEP), a two-step density gradient centrifugation (SDGC) approach employing sucrose, histodenz, and percoll, the SPIONs approach, which is based on the endocytosis of dextran coated nano-particles and their delivery to the lysosomal compartment, and the TMEM192-HA immunoprecipitation a 3 x HA tagged version of the lysosomal membrane protein TMEM192 used for lysosome isolation by anti-HA antibodies immobilized on magnetic beads. We evaluated the abundance and distributions of lysosomal, as well total proteins, allowing for the determination of lysosomal enrichment among the different strategies.

In mammalian cells, the lysosome is the main organelle for the degradation of macromolecules and the recycling of their building blocks. Correct lysosomal function is essential, and mutations in every known lysosomal hydrolase result in so-called lysosomal storage disorders, a group of rare and often fatal inherited diseases. Furthermore, it is becoming more and more apparent that lysosomes play also decisive roles in other diseases, such as cancer and common neurodegenerative disorders. This le ...[more]

Project description:The amino acid sequences of immunodominant domains of hemagglutinin (HA) on the surface of influenza A virus (IAV) evolve rapidly, producing viral variants. HA mediates receptor recognition, binding and cell entry, and serves as the target for IAV vaccines. Glycosylation, a post-translational modification that places large, branched polysaccharide molecules on proteins, can modulate the function of HA, and can shield antigenic regions allowing for viral evasion from immune responses. Our previous work showed that subtle changes in the HA protein sequence can have a measurable change in glycosylation. Thus, being able to measure quantitatively how glycosylation changes in viral variants is critical for understanding how HA function may change throughout viral evolution. Moreover, understanding quantitatively how the choice of viral expression systems affects glycosylation can help in the process of vaccine design and manufacture. Although IAV vaccines are most commonly expressed in chicken eggs, cell-based vaccines have many advantages and the adoption of more cell-based vaccines would be an important step in mitigating seasonal influenza and protecting against future pandemics. Here, we have investigated the use of data-independent acquisition (DIA) mass spectrometry for quantitative glycoproteomics. We found that DIA improved the sensitivity of glycopeptide detection for four variants of A/Switzerland/9715293/2013 IAV: WT and mutant, each expressed in chicken eggs and MDCK cells. We used the Tanimoto similarity metric to quantify changes in glycosylation between WT and mutant, and between egg-expressed and cell-expressed virus. Our DIA site-specific glycosylation similarity comparison of WT and mutant expressed in eggs confirmed our previous analysis while achieving greater depth of coverage. We found that sequence changes resulting from different viral expression systems affected distinct glycosylation sites of HA. Our methods can be applied to track glycosylation changes in circulating IAV variants to bolster the genomic surveillance already being done, for a more complete understanding of IAV evolution.

Project description:The cGAS-STING pathway forms a major component of the innate immune system. cGAS-STING signalling is induced by detection of either foreign (i.e. pathogenic) or mislocalised host double stranded (ds)DNA present within the cytosol. STING acts as the major signalling hub, where it controls activation of transcription factors IRF3 and NF-B for expression of type I interferons and inflammatory cytokines, respectively. Under resting conditions STING resides on the ER membrane. However, following activation STING traffics to the Golgi to initiate downstream signalling, and subsequently to endolysosomal regions for degradation and termination of signalling. However, while STING is known to be degraded by lysosomes, the mechanisms controlling its delivery remain poorly defined. Here we utilised a mass spectrometry approach to assess phosphorylation changes in primary macrophages following STING activation. This identified a large number of phosphorylation events in proteins involved in intracellular transport, including vesicular trafficking. We utilised high-temporal microscopy to track STING vesicular transport in live macrophages. We observed that while macrophages exhibit rapid degradation of STING (i.e., 4-6 h), basal STING protein levels return slowly (i.e., >24 h). Despite STING protein recovery, ultimately macrophages remain unresponsive to re-challenge with STING ligands. Using a combination of imaging and biochemical approaches we subsequently identify that the endosomal complexes required for transport (ESCRT) pathway detects ubiquitinated STING on endosomes, which facilitates the degradation of STING. Disrupting ESCRT recognition of STING via knockdown of the ESCRT-0 component HRS or inhibiting ESCRT function via overexpression of a dominant negative form of VPS4a enhances STING signalling and cytokine production. Therefore, we have characterised the mechanisms that controls effective termination of STING signalling. Dysregulation of STING localisation or its degradation has been implicated in several diseases including autoimmune, autoinflammatory and neuroinflammatory diseases, hence a clearer understanding of STING degradation is imperative for a better understanding of STING-dependent disease pathologies.
