A recent study conducted by an international research team from the US, Germany, and The Netherlands revealed that the Alpha variant of the coronavirus demonstrated a heightened attachment to human cells compared to other variants. This increased attachment was identified as a key factor contributing to the rapid transmission of the Alpha variant. In contrast, variants such as Beta and Gamma, known for their ability to evade immune responses, did not display this elevated attachment, impacting their spread among populations differently.
The research, published in the journal Nature Nanotechnology, attributes the changes in attachment strength to mutations in these COVID-19 variants. The study suggests that future variants could potentially combine strong attachment properties with other advantageous traits, leading to accelerated transmission rates. The investigation focused on comprehending the adhesion strength of various COVID-19 variants to human cells and its impact on the virus’s spread. Molecular dynamics simulation data provided detailed insights into the roles of amino acid residues in the spike protein’s binding interface. The team also conducted experiments to assess the force stability of the virus’s interaction with human cells.
Priscila Gomes, a postdoctoral researcher at Auburn University in the US, emphasized the study’s significance in understanding how mutations structurally influence the interaction between current and future variants and human proteins. Other participating universities included Ludwig Maximilian University of Munich, Germany, and Utrecht University, The Netherlands.
