Modulations of Homeostatic ACE2, CD147, GRP78 Pathways Correlate with Vascular and Endothelial Performance Markers during Pulmonary SARS-CoV-2 Infection. Cells 2024; 13:432. [PMID: 38474396 PMCID: PMC10930588 DOI: 10.3390/cells13050432] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Revised: 02/20/2024] [Accepted: 02/27/2024] [Indexed: 03/14/2024] Open
Abstract
The pathologic consequences of Coronavirus Disease-2019 (COVID-19) include elevated inflammation and dysregulated vascular functions associated with thrombosis. In general, disruption of vascular homeostasis and ensuing prothrombotic events are driven by activated platelets, monocytes, and macrophages, which form aggregates (thrombi) attached to the endothelium lining of vessel walls. However, molecular pathways underpinning the pathological interactions between myeloid cells and endothelium during COVID-19 remain undefined. Here, we tested the hypothesis that modulations in the expression of cellular receptors angiotensin-converting enzyme 2 (ACE2), CD147, and glucose-regulated protein 78 (GRP78), which are involved in homeostasis and endothelial performance, are the hallmark responses induced by SARS-CoV-2 infection. Cultured macrophages and lungs of hamster model systems were used to test this hypothesis. The results indicate that while macrophages and endothelial cells are less likely to support SARS-CoV-2 proliferation, these cells may readily respond to inflammatory stimuli generated by the infected lung epithelium. SARS-CoV-2 induced modulations of tested cellular receptors correlated with corresponding changes in the mRNA expression of coagulation cascade regulators and endothelial integrity components in infected hamster lungs. Among these markers, tissue factor (TF) had the best correlation for prothrombotic events during SARS-CoV-2 infection. Furthermore, the single-molecule fluorescence in situ hybridization (smFISH) method alone was sufficient to determine the peak and resolution phases of SARS-CoV-2 infection and enabled screening for cellular markers co-expressed with the virus. These findings suggest possible molecular pathways for exploration of novel drugs capable of blocking the prothrombotic shift events that exacerbate COVID-19 pathophysiology and control the disease.

Vettori M, Dima F, Henry BM, Carpenè G, Gelati M, Celegon G, Salvagno GL, Lippi G. Effects of Different Types of Recombinant SARS-CoV-2 Spike Protein on Circulating Monocytes' Structure. Int J Mol Sci 2023; 24:ijms24119373. [PMID: 37298324 DOI: 10.3390/ijms24119373] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 05/25/2023] [Accepted: 05/26/2023] [Indexed: 06/12/2023] Open
Abstract
This study investigated the biological effects on circulating monocytes after challenge with SARS-CoV-2 recombinant spike protein. Whole blood collected from seven ostensibly healthy healthcare workers was incubated for 15 min with 2 and 20 ng/mL final concentration of recombinant spike protein of Ancestral, Alpha, Delta, and Omicron variants. Samples were analyzed with Sysmex XN and DI-60 analyzers. Cellular complexity (i.e., the presence of granules, vacuoles and other cytoplasmic inclusions) increased in all samples challenged with the recombinant spike protein of the Ancestral, Alpha, and Delta variants, but not in those containing Omicron. The cellular content of nucleic acids was constantly decreased in most samples, achieving statistical significance in those containing 20 ng/mL of Alpha and Delta recombinant spike proteins. The heterogeneity of monocyte volumes significantly increased in all samples, achieving statistical significance in those containing 20 ng/mL of recombinant spike protein of the Ancestral, Alpha and Delta variants. The monocyte morphological abnormalities after spike protein challenge included dysmorphia, granulation, intense vacuolization, platelet phagocytosis, development of aberrant nuclei, and cytoplasmic extrusions. The SARS-CoV-2 spike protein triggers important monocyte morphological abnormalities, more evident in cells challenged with recombinant spike protein of the more clinically severe Alpha and Delta variants.

SARS-CoV-2 Delta (B.1.617.2) variant replicates and induces syncytia formation in human induced pluripotent stem cell-derived macrophages. PeerJ 2023; 11:e14918. [PMID: 36883057 PMCID: PMC9985896 DOI: 10.7717/peerj.14918] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Accepted: 01/26/2023] [Indexed: 03/06/2023] Open
Abstract
Alveolar macrophages are tissue-resident immune cells that protect epithelial cells in the alveoli from invasion by pathogens, including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Therefore, the interaction between macrophages and SARS-CoV-2 is inevitable. However, little is known about the role of macrophages in SARS-CoV-2 infection. Here, we generated macrophages from human induced pluripotent stem cells (hiPSCs) to investigate the susceptibility of hiPSC-derived macrophages (iMΦ) to the authentic SARS-CoV-2 Delta (B.1.617.2) and Omicron (B.1.1.529) variants as well as their gene expression profiles of proinflammatory cytokines during infection. With undetectable angiotensin-converting enzyme 2 (ACE2) mRNA and protein expression, iMΦ were susceptible to productive infection with the Delta variant, whereas infection of iMΦ with the Omicron variant was abortive. Interestingly, Delta induced cell-cell fusion or syncytia formation in iMΦ, which was not observed in Omicron-infected cells. However, iMΦ expressed moderate levels of proinflammatory cytokine genes in response to SARS-CoV-2 infection, in contrast to strong upregulation of these cytokine genes in response to polarization by lipopolysaccharide (LPS) and interferon-gamma (IFN-γ). Overall, our findings indicate that the SARS-CoV-2 Delta variant can replicate and cause syncytia formation in macrophages, suggesting that the Delta variant can enter cells with undetectable ACE2 levels and exhibit greater fusogenicity.
