SARS-CoV-2 ORF8 and the expression of cytokine in human macrophages

A new study has determined the production of the SARS-CoV-2 SP-dependent ORF8.

Research suggests toll-like receptor 4 appears to play role in severe COVID

A group of researchers re-evaluated their previously proposed hypothesis, which stated that the TLR4 activated by the spike glycoprotein S1 domain increases ACE2 expression and, thereby, aids in COVID-19 infection.

The role of natural killer cells in the fight against coronavirus infection

This study proposes a mathematical framework to analyze the effect of the viruses on type I interferon (IFN-I) signaling, which is part of the innate immune response. IFN-I brings about natural killer cell activation, which in turn causes the activation of macrophages.

Spike-containing virus-like particles induce robust sterilizing immunity against SARS-CoV-2 in macaques

A team of international scientists has recently developed virus-like particles (VLPs) by coating liposomes with the synthetic spike glycoprotein of SARS-CoV-2.

Cell-analysis method could pave the way for new vaccine strategies against tuberculosis

A new method that analyzes how individual immune cells react to the bacteria that cause tuberculosis could pave the way for new vaccine strategies against this deadly disease, and provide insights into fighting other infectious diseases around the world.

RUDN University biologists discover the way how macrophages respond to inflammation

RUDN University biologists discovered the way how macrophages (the cells of the "first line" immune response) respond to inflammation and identified how the immune response depends on their origin.

Study sheds light on immune processes involved in long COVID

Researchers in the United States have provided important insights into the immune processes that may be associated with post-acute sequelae of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection – also referred to as long COVID (coronavirus disease 2019).

Researchers unravel mechanisms that produce individualized metabolism in leukemia

A research collaboration based in Kumamoto University (Japan) has shown that lysine-specific demethylase 1 (LSD1), an enzyme involved in gene expression, produces individualized metabolism depending on the type of acute myeloid leukemia cells.

Is there a link between circadian rhythms and COVID-19 severity?

This study showed that the time of day of SARS-CoV-2 infection could impact the severity of the viral infection and the host immune response.

Differences in monocyte subsets between severe COVID-19 and long COVID

Researchers in the United States and Costa Rica have identified differences in the proportions of monocyte subsets that occur in severe cases of coronavirus disease 2019 (COVID-19) following infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and post-acute sequelae of COVID-19 (PASC), often referred to as “Long COVID”.

Could the activation of FcγRIII/CD16 by anti-spike SARS-CoV-2 antibodies independently determine COVID-19 severity?

A team of scientists from Germany recently investigated whether hyperactivation of immune receptors that recognize the Fc part of an IgG molecule (FcγR) can lead to immunopathologic changes in coronavirus disease 2019 (COVID-19) patients. They have observed that hyperactivation of FcγRIII (CD16) by proinflammatory IgG antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can significantly contribute to COVID-19 related immunopathology.

CD39+ monocyte count higher in pregnant than non-pregnant COVID-19 patients

A new study published on the bioRxiv* server describes the changes in the representation of a subset of activated monocytes in this group of patients.

Increased severity of COVID-19 in pregnancy

A new preprint on the medRxiv* server provides more evidence that COVID-19 likely causes a more serious phenotype to arise in pregnant women.

Could a fungus-derived compound reduce hyperinflammation in severe COVID-19?

New research from scientists at the University of Pennsylvania, USA, demonstrates that cyclosporine A (CSA), a calcineurin inhibitor that modulates cytokine production, may have potential antiviral properties against coronaviruses.

RIG-1 agonist shows potent antiviral efficacy against SARS-CoV-2 infection

A team of scientists from the United States has recently revealed the antiviral efficacy of stem-loop RNA 14, a RIG-1 agonist, in controlling severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in mice. The compound reduces the risk of severe coronavirus disease 2019 (COVID-19) by inhibiting viral replication in the lower respiratory tract. The study is currently available on the bioRxiv* preprint server.

Forkhead box O's potential therapeutic use in the treatment of COVID-19

In a recent study, Indian researchers from the Department of Biochemistry, University of Delhi, reviewed a possible vital coalition of FoxOs - the Forkhead Box O subfamily of protein transcription factors, with SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), the etiological agent of COVID-19 (coronavirus disease).

Metformin potently inhibits SARS-CoV-2-induced cytokine release in monocytes

An interesting new bioRxiv* preprint reports the suppression of monocyte glycolysis and cytokine production when exposed to the virus, following pretreatment with the commonly used drug, metformin.

Study finds molecular pathway that can explain how chronic kidney disease induces heart failure

According to the Global Burden of Disease Study 2017, close to nine percent of the global population lives with some form of chronic kidney disease, or CKD. Not only does the condition affect renal function, CKD has long been associated with increased risk of cardiovascular disease.

Function and regeneration of dendritic cells impaired in COVID-19

A group of researchers from Germany has investigated and analyzed circulating dendritic cells and monocyte subsets in 65 hospitalized COVID-19 patients with mild to severe presentations of the infection. A variety of patients were included in their study, from those who exhibited minor signs of acute disease to convalescents, as well as healthy controls
