ORF8 ∆382 Mutation: A Possible Viral Prognostic Biomarker for the Severity of the COVID-19
Since the initial onset of the current severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic from Wuhan, China in December 2019, the virus is now spread all around the world, and the disease is named COVID-19. Based on the WHO report on April 18, 2021, there are now more than 140 million confirmed cases and three millions deaths due to this disease[1]. The virus pathogenesis, cl...
متن کاملViral mutation rates.
Accurate estimates of virus mutation rates are important to understand the evolution of the viruses and to combat them. However, methods of estimation are varied and often complex. Here, we critically review over 40 original studies and establish criteria to facilitate comparative analyses. The mutation rates of 23 viruses are presented as substitutions per nucleotide per cell infection (s/n/c)...
متن کاملMechanisms of viral emergence
A number of virologic and environmental factors are involved in the emergence and re-emergence of viral disease. Viruses do not conservatively occupy a single and permanent ecological niche. Rather, due to their intrinsic capacity for genetic change, and to the evolvability of fitness levels, viruses display a potential to parasitize alternative host species. Mutation, recombination and genome ...
متن کاملCellular sensing of viral DNA and viral evasion mechanisms.
Mammalian cells detect foreign DNA introduced as free DNA or as a result of microbial infection, leading to the induction of innate immune responses that block microbial replication and the activation of mechanisms that epigenetically silence the genes encoded by the foreign DNA. A number of DNA sensors localized to a variety of sites within the cell have been identified, and this review focuse...
متن کاملViral Infections and their Role in Autoimmune Diseases, with Emphasis on Mechanisms and Molecular Interactions
Introduction: The exact cause of most autoimmune diseases is still unknown; however, several factors play a role in causing or exacerbating autoimmune reactions. In addition to environmental factors such as bacterial, parasitic, fungal and viral infections, factors such as genetic characteristics and lifestyle are also included. Infections caused by viruses usually trigger a strong immune respo...
