Chemical biomarker levels reflect varying severity of COVID-19 symptoms

Varying severity of COVID-19 symptoms in patients is reflected by levels of a chemical biomarker in their body which scientists say could be used to better manage treatments and other interventions, including vaccinations.

Low K777 concentrations inhibit cathepsin L and reduce SARS-CoV-2’s ability to infect host cell lines

For a long time, James McKerrow, MD, PhD, dean of the Skaggs School of Pharmacy and Pharmaceutical Sciences at University of California San Diego, has investigated neglected tropical diseases, which are chronic, disabling parasitic infections mainly affecting the poor and underserved communities in developing nations.

B.1.1.7 variant of SARS-CoV-2 spreading quickly in the United States

The faster-spreading B.1.1.7 variant of SARS-CoV-2 first detected in the United Kingdom, the coronavirus that causes COVID-19, is quickly on its way to becoming the dominant variant of the virus in the United States, according to a study from scientists at Scripps Research and the COVID-19 test maker Helix.

Salivary gland cells could play role in SARS-CoV-2 virus transmission

Scientists have shown that SARS-CoV-2, the virus that causes COVID-19, can infect specific cells in the salivary gland in the mouth.

New label-free immune profiling assay to assess rapidly changing host immune response

Researchers from Critical Analytics for Manufacturing Personalized-Medicine (CAMP), an Interdisciplinary Research Group (IRG) at the Singapore-MIT Alliance for Research and Technology (SMART), MIT's research enterprise in Singapore, have developed a new label-free immune profiling assay that profiles the rapidly changing host immune response in case of infection, in a departure from existing methods that focus on detecting the pathogens themselves, which can often be at low levels within a host.

Study shows SARS-CoV-2 antibodies wane at different rates

Researchers from Duke-NUS Medical School, the National Centre for Infectious Diseases (NCID), and the Agency for Science, Technology and Research (A*STAR) Infectious Diseases Labs have discovered that antibodies against SARS-CoV-2 decline at different speeds, and these antibodies last for only a few days in some people but remain for many years in other individuals.

Legal wildlife trade needs monitoring to reduce emerging zoonotic diseases

With three out of four newly emerging infectious human diseases originating in animals, there is an urgent need to monitor the legal trade in wildlife, according to new research by Vincent Nijman, Professor in Anthropology at Oxford Brookes University.

Genomics study examines the impact of COVID-19 on care homes

Care homes are at high risk of experiencing outbreaks of COVID-19, the disease caused by SARS-CoV-2. Older people and those affected by heart disease, respiratory disease and type 2 diabetes - all of which increase with age - are at greatest risk of severe disease and even death, making the care home population especially vulnerable.

Researchers identify gene variant associated with childhood asthma

Researchers at Henry Ford Health System, as part of a national asthma collaborative, have identified a gene variant associated with childhood asthma that underscores the importance of including diverse patient populations in research studies.

Study: Role of natural mosquito behavior on malaria transmission

Everyone knows 2 + 2 = 4, but what about mosquitoes plus malaria? Lauren Childs, an assistant professor in the Department of Mathematics at Virginia Tech, says there's an equation for that too.

Climate change may have played a direct role in the emergence of SARS-CoV-2

Global greenhouse gas emissions over the last century have made southern China a hotspot for bat-borne coronaviruses, by driving growth of forest habitat favored by bats.

Study provides a causal link between the Alzheimer's risk gene and COVID-19

A City of Hope-led research team found that the same gene that increases the risk for Alzheimer's disease, ApoE4, can increase the susceptibility to and severity of COVID-19.

Immunity of COVID-19 patients may rely on antibodies from previous coronavirus infections

The results of a study led by Northern Arizona University and the Translational Genomics Research Institute (TGen), an affiliate of City of Hope, suggest the immune systems of people infected with COVID-19 may rely on antibodies created during infections from earlier coronaviruses to help fight the disease.

Using proteomics to determine how long a corpse has been underwater

In this interview, AZoLifeSciences speaks to Dr. Noemi Procopio about her latest research which involved using bone proteomics to determine the length of time a corpse had been left underwater.

Study may lead to new treatments for autoimmune diseases

According to a research team, headed by Decio L. Eizirik, MD, PhD, a Scientific Director from the Indiana Biosciences Research Institute Diabetes Center, new treatments for autoimmune disorders can be identified by studying both target tissues and the immune system together.
