People coinfected with SARS-CoV-2 and cytomegalovirus found to be at increased risk of developing cardiovasculardisease

Abbreviation: AS, aortic stenosis; CMV, cytomegalovirus; HDs, healthy donors; mCOVID-19, unvaccinated individuals with mild/asymptomatic SARS-CoV-2 infection; NA, not applicable; SARS-CoV-2, severe acute respiratory syndrome; coronavirus 2; SD, standard deviation; T1, time point 1 ; T2, time point 2 ; vmCOVID-19, vaccinated individuals with mild/asymptomatic SARS-CoV-2 infection.

Finally, patients with AS were recruited from June 2019 to January 2020. Their samples were collected at the time of their cardiovascular surgery, according to the following criteria: surgery indicated for valve replacement; no history or presence of cancer, endocrine disorders, renal failure, liver or autoimmune disease, or SARS-CoV-2 infection; and no current immunosuppressive treatment. None of the individuals in the cohort were immunoglobulin M seropositive for CMV.

The following plug-ins were used to perform uniform manifold approximation and projection reduction and FlowSOM clustering analysis among CD4

Single-cell microglial transcriptomics during demyelination defines a microglial state required for lytic carcass clearance - Molecular NeurodegenerationSingle-cell microglial transcriptomics during demyelination defines a microglial state required for lytic carcass clearance - Molecular NeurodegenerationBackground Microglia regulate the response to injury and disease in the brain and spinal cord. In white matter diseases microglia may cause demyelination. However, how microglia respond and regulate demyelination is not fully understood. Methods To understand how microglia respond during demyelination, we fed mice cuprizone—a potent demyelinating agent—and assessed the dynamics of genetically fate-mapped microglia. We then used single-cell RNA sequencing to identify and track the microglial subpopulations that arise during demyelination. To understand how microglia contribute to the clearance of dead oligodendrocytes, we ablated microglia starting at the peak of cuprizone-induced cell death and used the viability dye acridine orange to monitor apoptotic and lytic cell morphologies after microglial ablation. Lastly, we treated serum-free primary microglial cultures to model distinct aspects of cuprizone-induced demyelination and assessed the response. Results The cuprizone diet generated a robust microglial response by week 4 of the diet. Single-cell RNA sequencing at this time point revealed the presence of several cuprizone-associated microglia (CAM) clusters. These clusters expressed a transcriptomic signature indicative of cytokine regulation and reactive oxygen species production with altered lysosomal and metabolic changes consistent with ongoing phagocytosis. Using acridine orange to monitor apoptotic and lytic cell death after microglial ablation, we found that microglia preferentially phagocytose lytic carcasses. In culture, microglia exposed to lytic carcasses partially recapitulated the CAM state, suggesting that phagocytosis contributes to this distinct microglial state during cuprizone demyelination. Conclusions Microglia serve multiple roles during demyelination, yet their transcriptomic state resembles other neurodegenerative conditions. The phagocytosis of cellular debris is likely a universal cause for a common neurodegenerative microglial state.
