Clinical and pulmonary function analysis in long-COVID revealed that long-term pulmonary dysfunction is associated with vascular inflammation pathways and metabolic syndrome

ABSTRACT: Several studies have reported diverse and prolonged symptoms after COVID-19; however, how long-term pulmonary dysfunction (L-TPD) post-COVID-19 is manifested, which variables support it, and which are the concomitant consequences remain unknown. In this study patients with L-TPD were identified according to their computer-tomography and diffusing capacity-for-carbon-monoxide evaluations at 4-month post-infection. Regarding the acute phase, L-TPD was favored in elderly patients with comorbidities, supported by pathways such as cardiac dysfunction and chemotaxis of phagocytes. At 4-months post-infection, L-TPD patients exhibited a restrictive lung condition favored by CXCL9, platelets and an inhibited FCgamma-receptor-mediated-phagocytosis due to reduced CD16 expression in their monocytes, suggesting that phagocytosis of virus-antibody immune complexes was compromised in this group. Finally, one-year post infection, patients with L-TPD worsened metabolic syndrome and augmented body mass index in comparison with other patient groups. Overall, our data suggest that COVID-19 survivors required a personalized follow-up and adequate intervention to reduce long-term sequelae and the appearance of further metabolic diseases.

ABPP-HT* - Deep meets fast for activity-based profiling of deubiquitylating enzymes using advanced DIA mass spectrometry methodsABPP-HT* - Deep meets fast for activity-based profiling of deubiquitylating enzymes using advanced DIA mass spectrometry methods

Project description:Activity-based protein profiling (ABPP) uses a combination of activity-based chemical probes with mass spectrometry (MS) to selectively characterise a particular enzyme or enzyme class. ABPP has proven invaluable for profiling enzymatic inhibitors in drug discovery. When applied to cell extracts and cells, challenging the ABP-enzyme complex formation with a small molecule can simultaneously inform on potency, selectivity, reversibility/binding affinity, permeability, and stability. ABPP can also be applied to pharmacodynamic studies to inform on cellular target engagement within specific organs when applied to in vivo models. Recently, we established separate high depth and high throughput ABPP (ABPP-HT) protocols for the profiling of deubiquitylating enzymes (DUBs). However, the combination of the two, deep and fast, in one method has been elusive. To further increase the sensitivity of the current ABPP-HT workflow we implemented state-of-the-art data-independent acquisition (DIA) and data-dependent acquisition (DDA) MS analysis tools. Hereby, we describe an improved methodology, ABPP-HT* (enhanced high-throughput-compatible activity-based protein profiling), that in combination with DIA MS methods allowed for the consistent profiling of 35-40 DUBs and provided a reduced number of missing values, whilst maintaining a throughput of 100 samples per day.

Heart LC-MS/MS of a primary carnitine deficiency mouse model

Project description:A previous animal model for primary carnitine deficiency (PCD) showed symptoms and died quickly, which did not match the characteristics of patients who remained seemingly asymptomatic for a long time. A new mouse model aimed to simulate the characteristics of seemingly asymptomatic was recently constructed. Possible mechanisms underlying the cardiac phenotype was investigated by proteomics.

Proteomic analysis neutrophils from COVID-19 patients

Project description:To go further insight into the involvement of neutrophils in COVID-19 clinical expression, we performed a proteomic analysis of this blood cell type in COVID-19 patients and two non-infected SARS-CoV-2 control groups composed of healthy subjects and ARDS patients hospitalized in intensive care unit (ICU) respectively. All patients were from Guadeloupe and represent a homogeneous population. We have performed a quantitative proteomic study of neutrophiles from French hot spot COVID region, Guadeloupe, confirming the activation of type I IFN pathway and in some target of IFN as TAP proteins, specifically in COVID patients, but not in hospitalized ARDS non-COVID patients and described modification of the NET proteome potentially associated with ARDS.

A systems immunology study comparing innate and adaptive immune responses in adults to COVID-19 mRNA (BNT162b2/mRNA-1273) and adenovirus vectored vaccines (ChAdOx1-S)

Project description:We longitudinally profiled plasma proteomes in 54 adults vaccinated with the BNT162b2 (Pfizer-BioNTech) or ChAdOx1-S (Oxford-AstraZeneca) vaccines. Blood was collected pre-vaccination (V0) and 1-7 days after the 1st doses (BNT162b2 or mRNA-1273, V1) to assess innate and early adaptive responses. We identified key differences in the immune responses induced by the ChAdOx1-S and BNT162b2 vaccines that were correlated with subsequent antigen-specific antibody and T cell responses or vaccine reactogenicity. We observed that vaccination with ChAdOx1-S but not BNT162b2 induced a memory-like response after the first dose, which was correlated with the expression of several proteins involved in complement and coagulation. The COVID-19 Vaccine Immune Responses Study (COVIRS) thus represents a major resource to understand the immunogenicity and reactogenicity of these COVID-19 vaccines.

Analysis of cryopreservation of human granulosa cells

Project description:Human primary granulosa cells (GCs) derived from women, undergoing oocyte retrieval, can be cultured and are a cellular model for the study of human ovarian functions. In vitro they change rapidly, resembling initially cells of the preovulatory follicle and then cells of the corpus luteum. They are derived from individual patients and their different medical history, lifestyle and age lead to heterogeneity. Thus, cells can rarely be ideally matched for cellular experiments or, if available, only in small quantities. We reasoned that cryopreservation of human GCs may be helpful. Previous studies indicated feasibility of such an approach, but low survival of GCs was reported and consequences on GC functionality were only partially evaluated. We tested a slow freezing protocol (employing FCS and DMSO) of GCs upon isolation from follicular fluid. We compared cryopreserved and subsequently thawed cells with fresh, not cryopreserved ones, from the same patients. About 80 % of human GCs survived freezing/thawing. Neither morphology, nor levels of cell-cell contact, mitochondrial and steroidogenic genes were different between the two groups in cells cultured for 1-5 days. A proteomic analysis revealed no statistical significance in the abundance of a total of 5962 proteins. Both groups produced comparable basal levels of progesterone and responded similarly to hCG with elevation of progesterone. Taken together, we describe a rapid and readily available method for the cryopreservation of human GCs. We anticipate that it will allow future large-scale experiments and may thereby improve cellular studies with human ovarian cells.

Deregulated Expression of the 14q32 miRNA Cluster in Clear Cell Renal Cell Carcinomas

Project description:Clear cell renal cell carcinomas (ccRCC) are characterized by arm-wide chromosomal alterations. Loss at 14q is associated with disease aggressiveness in ccRCC, which responds poorly to chemotherapeutics. The 14q locus contains one of the largest miRNA clusters in the human genome; however, little is known about the contribution of these miRNAs to ccRCC pathogenesis. In this regard, we investigated the expression pattern of selected miRNAs at the 14q32 locus in TCGA kidney tumors and in ccRCC cell lines. We validated that the miRNA cluster is downregulated in ccRCC (and cell lines) as well as in papillary kidney tumors relative to normal kidney tissues and primary renal proximal tubule epithelial (RPTEC) cells. We demonstrated that agents modulating expression of DNMT1 (e.g., 5-Aza-deoxycytidine) could modulate miRNA expression in ccRCC cell lines. Lysophosphatidic acid (LPA, a Lysophospholipid mediator elevated in ccRCC) not only increased labile iron content but also modulated expression of 14q32 miRNAs. Through an overexpression approach targeting a subset of 14q32 miRNAs (specifically at subcluster A: miR-431, miR-432, miR-127, and miR-433) in 769-P cells, we uncovered changes in cellular viability and claudin-1, a tight junction marker. A global proteomic approach was implemented using these miRNA overexpressing cell lines which uncovered ATXN2 as a highly downregulated target, which has a role in chronic kidney disease pathogenesis. Collectively, these findings support a contribution of miRNAs at 14q32 in ccRCC pathogenesis.

Sildenafil Combined with Controlled Hypothermia Mitigates Microglial Activation After Neonatal Hypoxia-Ischemia in Rat.

Project description:The only validated treatment to prevent brain damage associated with hypoxia-ischemia (HI) encephalopathy of the newborn is controlled hypothermia with limited benefits. Additional putative neuroprotective drug candidates include sildenafil citrate, a phosphodiesterase-type 5 inhibitor. The main objective of this preclinical study is to assess its ability to reduce HI-induced neuroinflammation, in particular through its potential effect on microglial activation. HI was induced in P10 Sprague–Dawley rats by unilateral carotid permanent artery occlusion and hypoxia (HI), and treated by either hypothermia (HT) alone, Sildenafil (Sild) alone or combined treatment (SildHT). Lesion size, glial activation were analyzed by immunohistochemistry, qRT-PCR and proteomic analyses performed at P13. Exposure to any treatment was not associated with significant reduction in lesions size both in cerebral cortex and hippocampus, 72h after HI. Significant reductions in either Iba1+ (within the ipsilateral hemisphere) or GFAP+ cells (within the ipsilateral hippocampus) were observed in SildHT group, but not in the other treatment groups. In microglia sorted cells, pro-inflammatory markers, ie. Il1b, Il6, Nos2, and CD86 were significantly downregulated in SildHT treatment group only. These changes were restricted to ipsilateral hemisphere, were not evidenced in sorted astrocytes, and were not sex-dependent. Proteomic analyses in sorted microglia refined the pro-inflammatory effect of HI and confirmed a biologically relevant impact of SildHT on specific molecular pathways including notably genes related to neutrophilic functions. Our findings demonstrate that Sildenafil combined with controlled hypothermia confers maximum effect to mitigate microglial activation induced by HI through complex proteomic regulation. The reduction of neuroinflammation induced by Sildenafil may represent an interesting therapeutic strategy for neonatal neuroprotection.

The Centriolar Satellite Component CEP131 timely regulates mitochondrial Apoptosis

Project description:Centriolar satellites are multiprotein aggregates that orbit the centrosome and govern centrosome homeostasis and primary cilia formation. In contrast to the scaffold PCM1, which nucleates centriolar satellites and has been linked to microtubule dynamics, autophagy, and intracellular trafficking, the functions of its close interactant CEP131 beyond ciliogenesis remain unclear. By using a knockout strategy in a T-cell line unable to form primary cilia, we report that, although dispensable for centriolar satellite assembly, CEP131 participates in optimal tubulin modifications and microtubule regrowth. Our unsupervised label-free proteomic analysis by quantitative mass spectrometry further uncovered both a mitochondrial and an anti-apoptotic signature. Without CEP131, mitochondria showed increased respiration and formed a more elongated network. In response to cell death inducers converging on mitochondria, knockout cells displayed delayed cytochrome c release from mitochondria, subsequent caspases activation, and ultimately in apoptosis. This defect in mitochondrial permeabilization was intrinsic as it could be recapitulated in vitro with isolated organelles. Together, these data extend the functions of CEP131 to life-and-death decisions and propose ways to interfere with mitochondrial apoptosis.
