Blood types and COVID-19 risk confirmed

Blood type may play a pivotal role in driving disease severity among coronavirus disease (COVID-19) patients. Genetic analysis of COVID-19 patients has shown that people with blood type O seemed to be protected against severe disease. In contrast, those with blood type A may experience complications tied to the viral infection.

SARS-CoV-2 mutation reduces S1 shedding, increases infective potential

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the seventh coronavirus known to infect humans. SARS-CoV-2 emerged in the last month of 2019 in Wuhan, China, sparking off the ongoing COVID-19 pandemic. This virus enters the host cells through receptor binding and membrane fusion between the viral and host cell membrane.

Effect of human genes on severity and infectivity of SARS-CoV-2

Now, a new paper published on the preprint server medRxiv* reports the results of an analysis of the association between the genetic variants in the patients and the clinical progression of the disease. The study included 332 patients hospitalized with COVID-19 in a single-center, with widely varying laboratory and clinical features. There were 25, 12, and 17 patients with asymptomatic, mild, and critical disease.

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).

Variations in genome’s 'dark matter' region can make patients susceptible to inflammatory diseases

A study led by researchers at the Babraham Institute in collaboration with the Wellcome Sanger Institute has uncovered how variations in a non-protein coding 'dark matter' region of the genome could make patients susceptible to complex autoimmune and allergic diseases such as inflammatory bowel disease.

Spike protein analysis from India's first SARS-CoV-2

A new study published on the preprint server bioRxiv analyzes viral spike protein sequences from the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak in West Bengal, India, comparing them with sequences from other Indian states and Wuhan, China.

Remdesivir shows powerful activity against SARS-CoV-2 in Vitro

Remdesivir is an antiviral first developed by Gilead in 2014 as a treatment for Ebola and Marburg viruses. However, scientists explored its possibilities as a broad-spectrum drug when it proved effective against SARS-CoV and MERS-CoV, coronaviruses which were responsible for earlier outbreaks.

Gut microbiome influences pattern of activation in rat’s brain during opioid addiction

When Sierra Simpson was in college, she was sick for a year with recurring fevers and vomiting. Her doctors couldn't figure out what she had. Suspecting a bacterial infection, they tried treating her with high doses of antibiotics.

CRISPR-Cas system can be used to effectively target colitis pathogen

Research at North Carolina State University shows that the CRISPR-Cas system can be used to effectively target and eliminate specific gut bacteria, in this case Clostridioides difficile, the pathogen that causes colitis - a chronic, degenerative disease of the colon.
