Biosensor-Enabled Deconvolution of the Avidity-Induced Affinity Enhancement for the SARS-CoV-2 Spike Protein and ACE2 Interaction

Aspen Rene Gutgsell et al.

Summary: Avidity is a common phenomenon employed by nature to achieve high-affinity interactions, while heterogeneity introduced from multivalent binding interactions complicates result analysis. In this study, an SPR-based assay was developed to control the heterogeneity and successfully deconvolute avidity-induced affinity enhancement for the SARS-CoV-2 spike protein and ACE2 interaction.

The role of the surface ligand on the performance of electrochemical SARS-CoV-2 antigen biosensors

Sabine Szunerits et al.

Summary: Point-of-care technologies and testing programs have the potential to improve diagnosis and disease surveillance significantly. With their portable nature, rapid results, and ability to be performed near patients or treatment facilities, these tests are especially useful in situations of limited resources. In the current COVID-19 pandemic, fast, accurate, efficient, and cost-effective point-of-care testing devices are crucial for controlling the spread of the virus.

Diagnostics for COVID-19: moving from pandemic response to control

Rosanna W. Peeling et al.

Summary: Diagnostics play a crucial role in the response to the COVID-19 pandemic. Molecular tests like PCR are recommended for confirming diagnosis in symptomatic individuals, while antigen rapid detection tests have the advantage of being easier to perform with faster results and lower cost. Antibody tests can inform public policy but should not be used as proof of immunity. All three types of tests continue to be important in transitioning from pandemic response to control.

Could SARS-CoV-2 Spike Protein Be Responsible for Long-COVID Syndrome?

Theoharis C. Theoharides

Summary: SARS-CoV-2 infects cells through its spike protein binding to the surface receptor, resulting in acute symptoms known as COVID-19. Increasing evidence suggests the development of a chronic condition called long-COVID, characterized by fatigue and neuropsychiatric symptoms. Studies have found that the spike protein may have neurotoxic effects, causing perivascular inflammation and neuro-inflammation, contributing to long-COVID symptoms.

Cross-reactivity of antibodies from non-hospitalized COVID-19 positive individuals against the native, B.1.351, B.1.617.2, and P.1 SARS-CoV-2 spike proteins

Maryam Hojjat Jodaylami et al.

Summary: Despite lower response observed for variant spike proteins, we report evidence of sustained humoral response against native, B.1.351, B.1.617.2, and P.1 variant spike proteins among non-hospitalized Canadian adults. The affinity (KD) measured between spike proteins and antibodies elicited in sera of infected and vaccinated individuals was invariant. Sera from vaccinated individuals had higher antibody levels and more efficiently inhibited spike-ACE-2 interactions compared to vaccine-naive individuals, showing the effectiveness of vaccination.
