SARS-CoV-2 immunity in the U.S. remains low

Seroprevalence studies indicate that less than 10% of people in the U. S. have detectable antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from July to September 2020.

Virus induced lymphocytes show promise for COVID-19 and future pandemics

Researchers in the United States have conducted a study demonstrating the potential of a novel therapeutic approach to treating coronavirus disease 2019 (COVID-19). The therapy augments the body’s T cell response to the causative agent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by providing a boost of rapidly expanded virus-specific T cells.

Highly functional immune response in asymptomatic SARS-CoV-2 infection

Researchers in Singapore have conducted a study showing that asymptomatic individuals infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – mount an efficient, balanced and coordinated cellular immune response that protects the host without appearing to trigger any pathological processes.

Combination therapy found to be effective against treatment-resistant hepatocellular carcinoma

A combination cancer therapy that is effective against treatment-resistant hepatocellular carcinoma (HCC) by inhibiting tumor growth and increasing survival has been identified by researchers at Massachusetts General Hospital.

Severe COVID-19 can produce high long-term neutralizing antibodies, study finds

A new study published by a team of scientists in Spain indicates that neutralizing immunity can last for up to 8 months, despite a steep drop in antibody titer over this time.

Could the keto diet help prevent or mitigate severe COVID-19?

A new study published in the journal of Translational Medicine reports that the ketogenic diet (KD) may be useful in this area, with its track history of effectual reduction of fat mass, anti-inflammatory and immunomodulatory effects, and consequent improvement of cardiovascular health.

SARS-CoV-2 launches multipronged attack against host cell protein synthesis, study finds

An interesting new study throws a flood of light on how SARS-CoV-2 accomplishes its mission to infect and replicate within host cells while evading the host immune response.

Could beta-blockers be a potential treatment for COVID-19?

News-Medical spoke to researchers about their latest research into beta-blockers, and how they could potentially be used to treat COVID-19.

COVID-19 studies have neglected to focus on mucosal immunity, researchers argue

Researchers suggest that COVID-19 studies should focus on how mucous membranes in the mouth and nose develop immunity to the SARS-CoV-2 virus.

Immunonutrition may improve COVID-19 patients' recovery

Researchers duo Emma Derbyshire and Joanne Delange from the Nutritional Insight, Surrey, United Kingdom, explore the role of immunonutrition – nutrition that boosts or influences the immune system for those over 65 years of age in COVID-19. Their study titled, “COVID-19: is there a role for immunonutrition, particularly in the over 65s?,” was released in the latest issue of the BMJ Nutrition, Prevention and Health.

HIV alters SARS-CoV-2 immune response without affecting COVID-19 symptoms or outcomes

In a preprint paper published on the medRxiv server, a team of researchers from various institutions in South Africa, the UK, and Europe discuss how they determined the impact of HIV on the COVID-19 immune response in KwaZulu-Natal, South Africa, which is an area with very high HIV prevalence.
