Females mount stronger T-cell response to SARS-CoV-2

A new study published on the preprint server medRxiv in June 2020 shows that immune cells, antibody levels, cytokine levels, and viral loads contribute to the sex difference seen in response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Seroprevalence of IgM and IgG against SARS-CoV-2 in China

A new study published in the journal Nature Medicine in June 2020 reports the seroprevalence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) across China. This may help to understand the actual prevalence of the virus in the current pandemic.

Immuno-oncology may accelerate the development of treatments for COVID-19

Researchers at Roswell Park Comprehensive Cancer Center have been actively engaged in the effort to develop treatments or other control strategies that can help communities worldwide to address the impacts of the COVID-19 pandemic.

COVID-19 lockdowns estimated to have prevented 3 million deaths across 11 European countries

Now, a new study by researchers at Imperial College London estimates that lockdowns prevented around 3.1 million deaths in 11 European countries. The modeling study, published in the journal Nature, highlights that social distancing measures worked in reducing the spread of the virus.

Immune cell discovery could help develop new treatments for hepatitis B

For the first time, researchers at The Westmead Institute for Medical Research have identified and described a new and unique subset of human cells that are involved in the immune response against hepatitis B (HBV) infection. The discovery could help develop new treatments for HBV and inform future vaccine design.

Anti-RBD antibodies shown to neutralize active SARS-CoV-2

A new study published on the preprint server bioRxiv* in June 2020 reports the discovery of multiple severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in samples from healthy donors, collected before the pandemic. These antibodies are capable of inhibiting the binding of the spike protein of the virus to the angiotensin-converting enzyme 2 (ACE2) molecule and can neutralize active infection of cells in culture.

COVID-19 produces lung inflammation in non-human primate experiments

A new study published on the online preprint server bioRxiv in June 2020 reports the successful use of three primate species to model the infection, pathogenesis, and clinical features associated with COVID-19. The research provides useful and immediately available models to test new vaccines and treatments.

Scientists harness cancer immunotherapy tools to identify targets for COVID-19 vaccine

Cancer researchers at Children's Hospital of Philadelphia have harnessed tools used for the development of cancer immunotherapies and adapted them to identify regions of the SARS-CoV-2 virus to target with a vaccine, employing the same approach used to elicit an immune response against cancer cells to stimulate an immune response against the virus.

Reflections and expectations: Are we handling COVID-19 in the right way?

COVID-19 Reflections: Severe lockdowns and Stay-at-Home orders have been hallmark of the national and global response to this Pandemic. They have been imposed with little precedent and scant evidence of their effectiveness as opposed to less restrictive social distancing measures.

Synthetic monoclonal antibodies effectively neutralize SARS-CoV-2 in laboratory conditions

In a new study available on the preprint server bioRxiv*, a multinational research group demonstrated how monoclonal antibodies strongly inhibit severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in vitro at even sub-nanomolar concentrations. This makes them a prime candidate for the treatment of coronavirus disease (COVID-19).

Georgia State researcher receives $1.95 million NIH grant to study cause of autoimmunity

Dr. Leszek Ignatowicz, a professor in the Institute for Biomedical Sciences at Georgia State University, has received a five-year, $1.95 million federal grant to study what causes autoimmunity in the human body.

Monocytes could be critical in dysregulated immunity in COVID-19

A new study by Spanish researchers as part of the GEN-COVID Project, and published on the preprint server medRxiv* in June 2020, suggests that monocytes are primarily involved in triggering the hyperinflammatory immune response that may underlie severe COVID-19 infection.

Tocilizumab in COVID-19 patients on mechanical ventilation

Now, a new study by researchers from the University of Michigan and published on the online preprint server medRxiv* in June 2020 shows that the cytokine inhibitor tocilizumab could have a favorable effect on survival in the most severely infected patients who require mechanical ventilation. This needs to be confirmed by clinical trials.

New strategy may facilitate development of multi-epitope peptide vaccine against SARS-CoV-2

By combining T and B lymphocyte analysis with manufacturability heuristic, researchers from the US and Germany proposed a set of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine peptides to use in subsequent animal studies and clinical trials. Their paper is currently available on the bioRxiv preprint server.

T cells can counteract dangerous phenomenon of mosquito-borne viruses

Every year, more than 68,000 people end up with a clinical case of Japanese encephalitis. One in four of these patients will die. The mosquito-borne virus, which is most common in Southeast Asia, also causes severe neurological damage and psychiatric disorders.

Study offers a deeper understanding of T cell immunity in the elderly

A study by Monash Biomedicine Discovery Institute (BDI) expands the understanding of the molecular pathways that control T cell function and survival and how it relates to declining T cell immunity in the elderly.

Long-term care facilities are a major driver of total COVID-19 deaths

Long-term care facilities (LTCFs) are a major driver of total COVID-19 deaths. Reported today in the Journal of the American Geriatrics Society, Boston Medical Center (BMC) and Boston University School of Medicine (BUSM) geriatricians Rossana Lau-Ng, Lisa Caruso and Thomas Perls studied the past month's case and death data reported by the Massachusetts Department of Health's COVID-19 daily Dashboard along with data provided by the Kaiser Family Foundation and other countries.
