Mitochondria dysfunction is implicated in cell death, inflammation, and autoimmunity. During viral infections, some viruses employ different strategies to disrupt mitochondria-dependent apoptosis, while others, including SARS-CoV-2, induce host apoptosis facilitate replication immune system modulation. Given mitochondrial DNAs (mtDNA) role as a pro-inflammatory damage-associated molecular pattern inflammatory diseases, we examined its levels the serum of COVID-19 patients found it be high relative healthy donors. Furthermore, comparison protein profiles between individuals SARS-CoV-2-infected revealed unique bands patients. Using mass spectroscopy, identified over 15 proteins, whose were 4- 780-fold higher. As mtDNA release from mitochondria mediated by oligomeric form mitochondrial-gatekeeper-the voltage-dependent anion-selective channel 1 (VDAC1)-we investigated whether SARS-CoV-2 alters VDAC1 expression. Among three selected small envelope (E), nucleocapsid (N), accessory 3b E-protein induced overexpression, oligomerization, release. Additionally, this led dysfunction, evidenced increased ROS production cytosolic Ca

Abstract Mitochondria play a crucial role in cellular functions, including immune responses and their dysfunction is observed SARS-CoV-2-infected cells. Here we investigated mitochondrial DNA (mtDNA) variations COVID-19 severity, focusing on potential impact of variants and/or haplogroups. PCR cases (n = 147) healthy controls (HC; n 40) were recruited, mt-DNA was amplified, sequenced analyzed for haplogroups genetic variations. categorized as Critical severe (CS; 40), Moderate (MOD; 43) Asymptomatic/mild (AMD; 64) disease. Haplogroup analysis showed major haplogroup M negatively associated with CS Whereas U positive association W an increased AMD COVID-19. Furthermore, 46 significantly the identified. More importantly mt.5186A > T ND2 gene high mutpred score Overall, are its severity Pakistani population.

Abstract Antibiotics are diverse in their utility clinical care. They widely prescribed for antimicrobial effect and used as modulators, although rarely, of non-infectious conditions, to influence immune responses, decrease morbidity improve quality life. This review provides a concise summary different classes antibiotics unique properties that allow them be the treatment conditions.
