Toll-like receptor 2 (TLR2) detects the SARS-CoV-2 envelope protein and generates inflammatory cytokines

Researchers at St Jude Children’s Research Hospital found that toll-like receptor 2 detects the SARS-CoV-2 envelope protein-producing inflammatory cytokines.

The spike proteins of SARS-CoV-2 B.1.617 and B.1.618 variants identified in India provide partial resistance to vaccine-elicited and therapeutic monoclonal antibodies

India’s surge in SARS-CoV-2 infections are linked to the new variants B.1.617 and B.1.618, with mutated spike proteins.

Presence of Anti-SARS-CoV-2 antibodies after 13 months of infection

A new study has been published on the medRxiv* preprint server which focuses on validating the serological assays using a large cohort of healthcare workers.

Glucosidase inhibitors hold promise as novel therapeutic agents against SARS-CoV-2

In a new study posted to the bioRxiv* preprint server, researchers from the United States report that two iminosugar glucosidase inhibitors have the ability to suppress the replication of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in tissue culture – at concentrations of at least 100 times lower than required for cytotoxic effects.

How SARS-CoV-2 evolved from a bat-to a human-adapted virus

New research published on the preprint server bioRxiv* performed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genomic simulations to understand the evolutionary transition from a bat-adapted SARS-CoV-2 to a human-adapted virus.

Study identifies mechanism behind SARS-CoV-2 fusion of host cells

The spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is mediated by the fusion of the spike protein to nearby healthy cells. New research by German researchers sheds light on how this happens.

Animal and insect invasions could shed light on COVID-19 transmission

Invasions by alien insect and animal species have much in common with outbreaks of infectious diseases and could tell us a great deal about how pandemics spread, according to a research paper published today.

Latest round of REACT-1 finds SARS-CoV-2 prevalence has halved since previous round

Researchers in the UK say the latest round of the REal-time Assessment of Community Transmission-1 (REACT-1) study has found that the prevalence of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – has fallen by 50%, compared with the previous round conducted in March of this year (2021).

Study investigates mental health consequences of COVID-19 geriatric care in nursing homes

No matter one's age, race, gender, socioeconomic status or political party, COVID-19 has impacted everyone at some level. That impact has been especially palpable for the approximately 1.3 million elderly Americans who reside in the country's 15,600 nursing homes.

Pandemic protocols in workplace resulted in less "sickness presenteeism"

Employer COVID-19 safety measures influenced worker precautions even when they were not on the clock, according to a new study out of Washington State University.

Researchers found disparities for COVID-19 testing and positivity rates in West Virginia

In studying COVID-19 testing and positivity rates in West Virginia between March and September 2020, West Virginia University researchers found disparities among Black residents and residents experiencing food insecurity.

New study will help investigate innate immune responses to viral infections

Researchers from Boston University School of Medicine (BUSM) report the formation of human cells containing a green fluorescent protein or GFP (one of the most important proteins in biology and fluorescence imaging) genetically fused with two interferon stimulated genes (ISGs), namely Viperin and ISG15.

Scientists provide a new approach to model infectious diseases

In the midst of a devastating global pandemic of wildlife origin and with future spillovers imminent as humans continue to come into closer contact with wildlife, infectious-disease models that consider the full ecological and anthropological contexts of disease transmission are critical to the health of all life.

Researchers propose new way to treat chronic lung condition

Traditionally, an infection is thought to happen when microbes - bacteria, fungi, or viruses - enter and multiply in the body, and its severity is associated with how prevalent the microbes are in the body.

People with venom allergies are more likely to have bone marrow disorder

Researchers at Michigan Medicine found that people with venom allergies are much more likely to suffer mastocytosis, a bone marrow disorder that causes higher risk of fatal reactions.

19 May 2021

Antibody response following SARS-CoV-2 mRNA vaccine is greater than natural infection

Researchers in the United States have provided the first evidence that messenger RNA (mRNA)-based vaccines against severe acute respiratory coronavirus 2 (SARS-CoV-2) induce a broader array of antibody subtypes against the viral spike protein than natural infection does.

Methotrexate impairs immunogenicity of BNT162b2 SARS-CoV-2 vaccine in patients with immune-mediated inflammatory diseases

Researchers from Germany and the USA recently investigated the cellular and humoral immune responses of patients with IMIDs on immunomodulatory treatment to mRNA COVID-19 vaccines. The research is published on the medRxiv* preprint server.
