Zinc-finger antiviral protein makes SARS-CoV-2 highly susceptible to interferons

By looking into zinc-finger antiviral proteins (ZAP), a new study from Germany and the United Kingdom (UK) and available on the preprint server bioRxiv suggests that zoonotic transmission of a coronavirus with a specific genetic make-up facilitated the pandemic spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), but also its sensitivity to interferons.

Study reveals biochemical alterations in patients with Lesch-Nyhan disease

An international study by the Institute of Neuroscience of the UAB, Emory University and Hospital Universitario La Paz, published in the PNAS journal, shows that patients suffering from Lesch-Nyhan, a rare neurological disease, present biochemical alterations in skin cells (fibroblasts), urine and cerebrospinal fluid.

Drug Teixobactin shows promise against drug-resistant superbugs

Two well-known superbugs are the gram-positive methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE). A new drug Teixobactin has shown promise against these microbes. The study titled, “The Killing Mechanism of Teixobactin against Methicillin-Resistant Staphylococcus aureus: an Untargeted Metabolomics Study,” was published in the latest issue of the journal Therapeutics and Prevention.

Genetic variations linked to COVID-19 severity

A new report by researchers from Thailand's Mahidol University and published on the preprint server medRxiv in May 2020 reports that the clinical severity of COVID-19 may be linked to the genetic makeup of the patient in addition to external factors.

Blood group type may affect susceptibility to COVID-19 respiratory failure

A group of over 120 researchers from various institutions across Europe has performed the first genome-wide association study to reveal host genetic factors that may contribute to respiratory failure in cases of coronavirus disease 209 (COVID-19).

SARS-CoV-2 emergence could be due to genetic selection and recombination

Researchers have found that genetic selection and recombination could be behind the emergence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that leads to acute respiratory distress syndrome (ARDS) or COVID-19 disease. This research could explain COVID-19 pandemic and its emergence. The study titled, “Emergence of SARS-CoV-2 through recombination and strong purifying selection,” was published in the journal Science Advances.

Genomic variation and descent of SARS-CoV-2 strains in India

The pandemic of COVID-19 that is still affecting over 188 countries and territories the world over has taken over 359,000 lives in just under five months, while affecting at least 5.8 million people. Different strains have diverged from the original strain detected in Wuhan, China.

Research provides important insights into genetic adaptation of SARS-CoV-2 to humans

In their groundbreaking paper available on the preprint server medRxiv, University of Pittsburgh researchers were appraising signals of SARS-CoV-2 genome evolution and found that purifying selection (i.e., removal of deleterious mutations) represents the dominant trait during early coronavirus disease (COVID-19) pandemic - suggesting that the virus will evolve as it diversifies in a growing number of hosts.

Frog brain discovery may pave the way for repairing birth defects in humans

A team of researchers from Tufts University, Universitat de Valencia, and Harvard University has discovered that the brains of developing frog embryos damaged by nicotine exposure can be repaired by using “ionoceuticals” that can help in the recovery of bioelectric patterns in the embryo.

Researchers analyze data on RNA structure of tick-borne encephalitis virus

Researchers from Sechenov University together with colleagues from several Russian institutes analyzed data on the RNA structure of tick-borne encephalitis virus.

Prediction of incubation period for COVID-19 and other viruses

A new study published on the preprint server bioRxiv* in May 2020 provides a method to estimate the incubation period for any new pathogen, which could help to define the optimal quarantine period necessary to keep the spread of the causative agent in check.

COVID-19 in farmed Mink in the Netherlands

A new study published on the preprint server bioRxiv in May 2020 reports the development of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in farmed mink in two locations in the Netherlands.

Study shows how RNA editing affects the replication of COVID-19 virus

Two human deaminase enzymes edit the RNA of the SARS-CoV-2 virus when it enters a patient's body, with implications for the evolution of the virus and the spread of the infection, according to a new study.

Human immune repertoire may not commonly produce cross-neutralizing antibodies to coronaviruses

Patients infected with either severe acute respiratory syndrome coronavirus (SARS-CoV) or SARS-CoV-2 produce antibodies that bind to the other coronavirus, but the cross-reactive antibodies are not cross protective, at least in cell-culture experiments, researchers report May 17 in the journal Cell Reports.

Host-virus interaction drives adaptive mutation in bat CoV related to SARS-CoVs

Virus and receptor diversity is shaped by the need to evolve advanced weaponry to facilitate virus entry and infection, on the one hand, and host resistance, on the other. A new paper published on the preprint server bioRxiv* shows how this mechanism operates in a bat coronavirus, which is related to the earlier SARS coronavirus.

SARS-CoV-2 cell entry affinity varies across different host species

A new study from India, currently available on the preprint server bioRxiv*, estimated the probability and readiness of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to infect cells of different animal species – and revealed many of them that could act as disease carriers.

Study provides genetic explanation behind the sex bias observed in certain diseases

Some diseases exhibit a clear sex bias, occurring more often, hitting harder or eliciting different symptoms in men or women.

Genomic sequences from all over the world help fight SARS-CoV-2

As the COVID-19 pandemic rages across the world, killing hundreds of thousands and infecting over 4.1 million, researchers are racing against time to understand the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The SARS-CoV-2 genome has now been sequenced in many different regions of the world, and researchers are collaborating by sharing information to better understand the make-up and mutations that the virus has undergone.
