Impaired cytotoxic T cell response found in in elderly COVID-19 patients

Although people of any age can become infected with SARS-CoV-2, the virus that causes COVID-19, elderly patients face a higher risk of severity and death than younger patients.

Study detects key differences in immune responses of adults and children with COVID-19

The first study comparing the immune responses of adults and children with COVID-19 has detected key differences that may contribute to understanding why children usually have milder disease than adults.

Strength, duration of immunity will shape the future trajectory of COVID-19

New research suggests that the impact of natural and vaccine-induced immunity will be key factors in shaping the future trajectory of the global coronavirus pandemic, known as COVID-19.

COVID-19 mitigation efforts significantly decrease influenza activity

The mitigation strategies implemented to curb the spread of COVID-19 appears to reduce the transmission of influenza in the United States, Australia, Chile, and South Africa. These strategies may augment influenza vaccines, especially for high-risk populations during the seasonal influenza transmission.

Screening university students could reduce community COVID-19 burden

Researchers in Canada and the United States report that screening students for infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as universities re-open this fall could reduce the burden of coronavirus disease 2019 (COVID-19) in the broader community.

COVID-19 lockdown measures reduced air pollution in Southeast Asia

In an attempt to contain the spread of the disease, many countries worldwide, including Malaysia and other Southeast Asian (SEA) countries, have enforced lockdowns of varying degrees, which has inadvertently caused some positive changes to the environment.

A cost-effective scalable production of SARS-CoV-2 RBD in yeast

A new study by the Argentinian AntiCovid Consortium and published in the preprint server bioRxiv* in September 2020 reports on the successful characterization of the conformation and stability of the SARS-CoV-2 spike protein receptor-binding domain (RBD) in two different cell systems. This may help to accelerate the development of vaccines and neutralizing antibodies.

Research underlines SARS-CoV-2 N-terminal domain of Nsp1 as a potential drug target

A recent study reveals how the non-structural protein 1 (NSP1) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) plays a crucial role in inhibiting the host cell protein synthesis but simultaneously facilitating the viral protein synthesis.

Oncology nurses should be routinely tested for SARS-CoV-2, warn researchers

Researchers from the NHS Foundation Trust, University of Cambridge and Cambridge Clinical Laboratories have warned that until a vaccine for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) becomes available, antigen and antibody testing should be carried out among oncology nurses as part of routine patient care.

BU researchers find how SARS-CoV-2 infection may drive deadly lung inflammation

Responding to the COVID-19 pandemic caused by the novel coronavirus, SARS-CoV-2, requires models that can duplicate disease development in humans, identify potential targets and enable drug testing.

Flu vaccine does not increase a person's COVID-19 risk, finds study

A new Cleveland Clinic study has found that receiving the influenza vaccine does not increase a person's risk for contracting COVID-19 or worsen associated morbidity or mortality.

CDC updates coronavirus guidelines to recognize airborne spread

Early on in the pandemic, it was thought that the virus was only spread via respiratory droplets. However, scientific research soon showed it also to be an airborne virus. Now, the U.S. Centers for Disease Control and Prevention (CDC) has updated its guideline, acknowledging that the virus can hang in the air, fueling its spread.

Soluble ACE2 microbody blocks SARS-CoV-2 entry into lung cells

A new study by researchers at NYU Langone Medical Center and Weill Cornell Medical College and published on the preprint server bioRxiv* in September 2020 reports the potential of an angiotensin-converting enzyme 2 (ACE2)-antibody Fc complex in a new format that seems to offer more significant inhibition of SARS-CoV-2.

COVAM assay may help select convalescent plasma units for treatment of acute COVID-19

A recent study published on the preprint server bioRxiv* seeks to establish the pattern of antibody reactivity in COVID-19 convalescent plasma (CCP), which is widely being used as a therapy for seriously ill COVID-19 patients.

21 Sep 2020

In vitro testing suggests effective novel drug combinations for SARS-CoV-2

A recent study published on the preprint server bioRxiv* in September 2020 shows the value of drug combinations to enhance the therapeutic and preventive efficacy of such repositioned drugs in standard antiviral therapy.

Chinese workers knowledge, attitudes and practices regarding COVID-19

In new research, scientists in China have looked at the knowledge, attitudes, and practices regarding COVID-19 among Chinese workers. The research paper titled, “Knowledge, attitudes, and practices related to Coronavirus disease 2019 during the outbreak among workers in China: A large cross-sectional study,” is published in the latest issue of the journal PLOS Neglected Tropical Diseases.

SARS-CoV-2 infects monocytes and macrophages, without cytopathic effect

A team of researchers from Aix-Marseille Univ, IHU-Méditerranée Infection, Institut Paoli Calmettes and Laboratoire d’Immunologie, Marseille, France, conducted experiments to determine if SARS-CoV-2 can affect the myeloid compartment or infect monocytes and macrophages.

Scientists investigate active plasma metabolite of remdesivir in SARS-CoV-2 mouse model

Using mouse models, scientists have investigated the active plasma metabolite of remdesivir, GS-441 524, and hydroxychloroquine as possible drug candidates in COVID-19. The research shows GS-441 524 could be an effective therapeutic drug against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), while at the same time discounting hydroxychloroquine as a reliable anti-viral.

Lopinavir-ritonavir does not suppress SARS-CoV-2 activity in vitro

Among them is the combination of lopinavir and ritonavir, which have been in use in an attempt to reduce the severity of the disease. However, a new South Korean study published on the preprint server bioRxiv in September 2020 shows that this combination is ineffective against the virus.
