In their recent study posted to the preprint server bioRxiv*, the researchers from China have shown that tuftsin, a natural phagocytosis-stimulating peptide, can effectively impair the binding of SARS-CoV-2 spike S1 subunit to ACE2 receptor in a dose-dependent manner and therefore can be considered a potential drug against SARS-CoV-2 infection.

Scientists at The University of Texas MD Anderson Cancer Center and Northwestern Medicine have identified natural extracellular vesicles containing the ACE2 protein (evACE2) in the blood of COVID-19 patients that can block infection from broad strains of SARS-CoV-2 virus in preclinical studies. The study was published today in Nature Communications.

To gain a better understanding of the antigenic properties of Mu and A.2.5 Spikes, Canadian scientists evaluated their capacity to interact with ACE2 and performed binding and neutralization assays with plasma from vaccinated individuals.

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.

In a new study, researchers used a cell-cell fusion assay to extract potentially cleaved spike protein products from syncytia in order to explore the functional and biochemical characteristics of spike (S) protein when it engages its receptor ACE2 in living cells.

An interesting preprint research paper describes structural changes resulting from the multiple mutations found in the recent Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). SARS-CoV-2 is the causative agent behind the coronavirus disease 2019 (COVID-19) pandemic. In addition, the research describes the consequent effects of these changes on Omicron’s infectivity and immune evasion capabilities.

New study findings show that the clinical-grade soluble ACE2 effectively inhibits the SARS-CoV-2 Omicron variant, which proves the principle of an effective therapeutic approach against Omicron-driven COVID-19 infections.

Now in new research, scientists from the University of Leicester have been investigating how these mutations alter the affinities of RBDs to ACE2.

A new study highlights the potential evolutionary trade-off observed in the omicron variant, detailing the dynamics of the protein structure, its interactions, and subsequent effects.
