| Study Title | Lipidomic characterization of Jurkat-derived T cell line in which the chaperonin complex CCT has been partially silenced |
| Study Type | Untargeted Lipidomics |
| Study Summary | When the chaperonin complex CCT is partially silenced in Jurkat-derived T cell line J77 E61, we observe changes in the production of exosomes and in their composition. Thus, to explore the bases of these alterations and find possible new mechanisms of exosome biosynthesis regulation we characterized the lipidome content in cells where the chaperonin complex CCT was partially silent (CCT) and controls (CTRL). We analyzed 5 biological replicates containing 3 × 106 cells using LC-MS in positive and negative polarity mode. For quality control, 5 QCs samples and 4 blanks were also included in the analysis (total 19 samples and 2 groups). |

| Project Title: | Chaperonin CCT controls cell fueling by lipids and extracellular vesicle production through kinesin dynamics |
| Project Type: | Untargeted Lipidomics |
| Project Summary: | Cells regulate their protein content through different processes including gene transcription, protein translation, post-translational modification, secretion, degradation and recycling. The complexity of this network and its dynamic regulation remains mostly unexplored. A plethora of intracellular elements can be incorporated into multivesicular bodies (MVB) to be secreted as soluble components or extracellular vesicles (EVs). By profiling the proteome of EVs from T cells, we have found the subunits of the chaperonin CCT, involved in the correct folding of particular proteins. By limiting CCT content after siRNA silencing, cells shift the dynamics of lipid droplets, peroxisomes and the endolysosomal system, showing an accumulation of MVBs that leads to increased EV production and an altered lipid composition. Also, their metabolic profile is shifted towards a lipid-dependent metabolism. This is exerted through the dynamic regulation of microtubule-based kinesin motor. |
