Current vaccines against COVID-19 elicit immune responses that are overall strong but wane rapidly. As a consequence, the necessary booster shots have contributed to vaccine fatigue. Hence, would provide lasting protection needed, still unavailable. Cytomegaloviruses (CMVs) and uniquely responses. Used as vectors, they may be attractive tools obviate need for boosters. Therefore, we tested murine CMV (MCMV) vector in relevant preclinical models of immunization challenge. We previously developed recombinant MCMV expressing spike protein ancestral SARS-CoV-2 (MCMV

Background/Objectives: Premature ovarian insufficiency (POI) is a disorder that affects women under the age of 40. It characterized by decreased function, elevated gonadotropin levels, and estradiol. SARS-CoV-2 disrupts function largely through oxidative stress, inflammation, immunological dysregulation, which are enhanced its entrance into tissues via ACE2 receptors. The purpose this comprehensive review was to investigate molecular pathways link infection POI analyze their consequences for reserve fertility. Methods: We searched databases such as PubMed, Scopus, EMBASE, Google Scholar papers published between 2020 2024. Eligible studies investigated effects on including hormonal indicators anti-Müllerian hormone (AMH) follicle-stimulating (FSH), oocyte quality, reserve. data were compiled complete examination molecules clinical findings. Increased inflammatory indicators, interleukin-6 NLRP3 inflammasome activation, impaired homeostasis. Anti-SARS-CoV-2 antibodies in follicular fluid could have quality. Observational showed transitory decreases AMH changed FSH levels following infection, with variable antral follicle count IVF results.

While most alterations temporary, long-term reproductive remain unknown. Continuous monitoring specific treatments required reduce risks associated COVID-19.

Abstract Severe acute respiratory syndrome coronavirus‐2 (SARS‐CoV‐2) is responsible for coronavirus disease of 2019 (COVID‐19) that infected more than 760 million people worldwide with over 6.8 deaths to date. COVID‐19 one the most challenging diseases our times due nature its spread, effect on multiple organs, and an inability predict prognosis, ranging from being completely asymptomatic death. Upon infection, SARS‐CoV‐2 alters host immune response by changing host‐transcriptional machinery. MicroRNAs (miRNAs) are regarded as post‐transcriptional regulators gene expression can be perturbed invading viruses. Several in vitro vivo studies have reported such dysregulation miRNA upon infection. Some this could occur anti‐viral viral Viruses themselves counteract mounting their own pro‐viral facilitates virus aspect which may cause pathogenesis. Thus, miRNAs serve possible biomarkers people. In current review, we summarised analysed existing data about patients determine concordance between studies, identified those potential during progression, death, even other co‐morbidities. Having vital not only predicting but also development novel miRNA‐based anti‐virals therapeutics become invaluable case emergence new variants pandemic future.
