Study shows SARS-CoV-2 prompts NLRP3 inflammasome activation through spike-ACE2 receptor interaction

New research assesses the NLR family pyrin domain containing 3 (NLRP3) inflammasome activation in response to SARS-CoV-2 and its spike protein, and the effects of this exposure in the presence of a-synuclein protein aggregate fibrils.

Exploring the systemic infection of SARS-CoV-2 in a wild leopard in India

A new study focused on the pathomorphological and virological characterization of SARS-CoV-2 in naturally infected, wild Indian Leopard.

Quantification of SARS-CoV-2 variants in wastewater samples

In a new study, a team of researchers introduced a novel method to estimate the proportion of different SARS-CoV-2 strains in wastewater samples.

Better global health equality could prevent emergence of future SARS-CoV-2 variants of concern

In a new study, researchers used a simple phenomenological model to investigate the role of immunocompromised hosts in SARS-CoV-2 antigenic development.

Study suggests vaccinated Omicron cases are unlikely to shed infectious virus 10 days after diagnosis or symptom onset

Researchers have been investigating the Omicron epidemic in Japan and have recently released an early report on the infectious period of the disease.

Dexamethasone shown to upregulate innate and adaptive immune responses in COVID-19 acute respiratory distress syndrome patients

In a new study, researchers used per protocol bronchoalveolar lavage fluid (BALF) samples after intubation to evaluate the transcriptomic profiles of the local pulmonary host responses during early-stage severe coronavirus disease 2019 (COVID-19) acute respiratory distress syndrome (CARDS), non-COVID-19 ARDS, and sepsis.

17 Jan 2022

Study demonstrates that intra-host SARS-CoV-2 variants with reduced infectivity are developed during infection

A new paper discusses the appearance of quasi-species in a single host with prolonged infection, with different rates of infectivity and sensitivity to neutralization by antibodies elicited by the Pfizer vaccine or those present in convalescent plasma.

17 Jan 2022

Study investigates whether immune responses to BNT162b2 vaccine differ in subjects with and without prior SARS-CoV-2 infection

A new paper published in the journal JCI Insight reports on the differential levels of immunity achieved in those with and without a history of prior infection with the virus following one and two doses of the earliest vaccines to be approved for emergency use.

17 Jan 2022

Study identifies cellular receptors for alphaviruses shared across mosquitoes, humans, and animals

A new study led by researchers at Harvard Medical School has identified a set of cellular receptors for at least three related alphaviruses shared across mosquitoes, humans, and animals that host the virus.

Pathogens turn off mitochondrial defense by hijacking a normal cellular response to stress

Mitochondria are known as energy suppliers for our cells, but they also play an important role in the defense against pathogens. They can initiate immune responses, and deprive pathogens of the nutrients they need to grow.
