About 15% of COVID-19-related deaths linked to long-term exposure to air pollution

Long-term exposure to air pollution has been linked to an increased risk of dying from COVID-19 and, for the first time, a study has estimated the proportion of deaths from the coronavirus that could be attributed to the exacerbating effects of air pollution for every country in the world.

Study better reveals the function and behavior of macrophages in cancer growth

Macrophages, cells that help engulf and destroy harmful organisms in the body, tend to be characterized as the Jekyll and Hyde of the immune system.

Phase 1 trial results of gorilla adenovirus vaccine for COVID-19

A recent study published on the preprint server bioRxiv* in October 2020 reports the development of a novel vaccine based on a simian adenoviral vector obtained from a group C gorilla isolate called GRAd32. This could help speed up vaccine development.

Startling high SARS-CoV-2 seroprevalence in Veracruz, Mexico

A surprising new study published on the preprint server medRxiv in October 2020 reports a very high seroprevalence of IgG antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the city of Vera Cruz, Mexico. They are among the highest to be reported anywhere in the world.

Mathematical modeling study offers new insights into optimal timing of antiviral therapies against COVID-19

A new mathematical modeling study by Ashish Goyal and colleagues, informed by data collected from 25 patients hospitalized with COVID-19 in 4 different countries, offers some important new insights into the optimal timing of 4 different antiviral therapies to combat the disease.

Neutrophils have more functions in the body than previously thought

Scientists at the Centro Nacional de Investigaciones Cardiovasculares have discovered that neutrophils, the most abundant cells of the innate immune system, have many more functions in the body than previously thought.

Study: 90% of patients have detectable antibodies up to 7 months post contracting COVID-19

A new study led by Marc Veldhoen, principal investigator at Instituto de Medicina Molecular João Lobo Antunes (iMM; Portugal) with an interdisciplinary team of clinicians and researchers from Faculdade de Medicina da Universidade de Lisboa (FMUL) and Centro Hospitalar Lisboa Norte (CHLN) and collaborators at Instituto Português do Sangue e Transplantação (IPST), shows that 90% of subjects have detectable antibodies 40 days up to 7 months post contracting COVID-19.

Nigeria safely relaunches accelerated yellow fever vaccination campaigns

While combatting multiple public health challenges, including the COVID-19 pandemic, the Government of Nigeria, with support of the World Health Organization (WHO) and Gavi, the Vaccine Alliance will safely relaunch an accelerated series of mass preventive vaccination campaigns to protect Nigerians against yellow fever (YF).

Intestinal microbiota offers new prospects for treating celiac disease

Celiac disease is an immune disease of the intestine that affects more than 1% of the population. It is characterised by gluten intolerance that causes inflammation of the gut, abdominal pain and diarrhoea, and can lead to weight loss and deficiencies among patients.

New research may shed light on challenges of developing universal flu vaccine

New research from an immunology team at the University of Chicago may shed light on the challenges of developing a universal flu vaccine that would provide long-lasting and broad protection against influenza viruses.

Researchers develop a novel method to test for COVID-19 antibodies

When Dr. Stephen Smith of Seattle Children's Research Institute came down with muscle aches, gastrointestinal distress and a sudden loss of smell in late February, he suspected he had COVID-19.

Researchers show a simple way to protect transplanted islets from rejection

Type 1 diabetes, or T1D, results from the autoimmune destruction of the insulin-producing cells of the pancreas. People with T1D require exogenous insulin and suffer swings in the levels of glucose in the blood that impact life expectancy and increase risks of cardiovascular disease, neuropathies and kidney failure.

Initial lockdown in France substantially curbed COVID-19, but many remain susceptible to the virus

Now, a new study by researchers at the Santé Publique France conducted seroprevalence estimates in France, one of the countries with high COVID-19 cases in Europe.

Study reveals developmental changes of the immune system during first week of life

Within the womb, a human fetus benefits from the protection of the placenta, limiting their contact with pathogens.

Researchers assess molecular basis of SARS-CoV-2 severity and poor outcomes in lung disease

A recent study published on the preprint server bioRxiv in October 2020 shows that in patients with chronic lung disease, the pattern of gene expression in the different types of cell changes such that the lung epithelium is prepared to tackle SARS-CoV-2 infection. Also, the altered gene programs have an impact on the immune response.

COVID-19 containment measures affecting other seasonal respiratory viruses

A recent study published on the preprint server medRxiv* in October 2020 indicates that so far, the containment measures put in place to prevent the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have effectively prevented the transmission of many other respiratory viruses.
