Altered Mitochondrial Respiration in Peripheral Blood Mononuclear Cells of Post-Acute Sequelae of SARS-CoV-2 Infection

Authors: Sahera Dirajlal-Fargo, David P Maison, Jared C Durieux, Anastasia Andrukhiv, Nicholas Funderburg, Kate Ailstock, Mariana Gerschenson, Grace A Mccomsey Published in: Mitochondrion, 75 (2024) 101849 Date: February 2024 Study Overview: This research investigates the mitochondrial function in peripheral blood mononuclear cells (PBMCs) in individuals with post-acute sequelae of SARS-CoV-2 (PASC), commonly known as Long COVID. The study compares mitochondrial respiration in three groups: those without a history of COVID-19, those who had COVID-19 but fully recovered, and those with PASC. Key Findings: Funding and Conflicts of Interest: This summary provides a comprehensive overview of the study, highlighting its significant…

Persistent SARS-CoV-2 infection: significance and implications

The study “Persistent SARS-CoV-2 infection: significance and implications” delves into the complexities and challenges posed by prolonged SARS-CoV-2 infections, especially in immunocompromised individuals. These persistent infections represent a significant clinical and public health concern due to their potential role in the emergence of novel virus variants through ongoing viral replication and evolution. Key Points from the Study: Conclusions: The study underscores the urgent need for a concerted effort in research, clinical management, and public health strategies to address persistent SARS-CoV-2 infections. By improving our understanding of these infections, developing effective diagnostics and treatments, and implementing robust surveillance, we can mitigate…

Multiple layers of innate immune response antagonism of SARS-CoV-2

The study, titled “Multiple layers of innate immune response antagonism of SARS-CoV-2,” presents an extensive analysis of the role of various SARS-CoV-2 proteins in modulating the host’s innate immune response. The researchers focused on twelve specific viral proteins, including NSP1, NSP2, NSP3, NSP6, NSP12, NSP13, NSP14, NSP15, NSP16, ORF3a, ORF6, and ORF8. They utilized a SARS-CoV-2 bacterial artificial chromosome combined with en passant mutagenesis to generate a series of infectious recombinant SARS-CoV-2 viruses, each carrying mutations in one of these proteins. Key findings of the study include: In summary, this research provides valuable insights into the complex interplay between SARS-CoV-2…

Persistence, prevalence, and polymorphism of sequelae after COVID-19 in young adults

COVID-19’s long-term impact on young adults has been an area of growing concern and interest. A comprehensive study titled “Persistence, prevalence, and polymorphism of sequelae after COVID-19 in young adults,” led by Jeremy Werner Deuel and others, sheds light on this critical issue. Here’s a detailed summary of their findings and methodology: Background The study, conducted on young Swiss Armed Forces personnel, aimed to understand the sequelae (after-effects) of COVID-19, especially in non-hospitalized young adults. This demographic is significant as it encompasses a large portion of the workforce, including healthcare workers. Methodology The research was a prospective longitudinal cohort study…
