Interaction of SARS-CoV-2 with host cells and antibodies: experiment and simulation

Chem. Soc. Rev. 2023, 52 (18), 6497-6553

SARS-CoV-2 Life Cycle and How Antibodies Bind to and Inhibit SARS-CoV-2 Entry into Human Cells

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the primary etiological agent responsible for the catastrophic global COVID-19 pandemic, as officially declared by the World Health Organization (WHO) in March 2020. This pandemic has infected more than 700 million people and claimed the lives of more than seven million people worldwide. In Poland, according to official statistics, there are about 6.5 million infected people and 120 thousand deaths. Notable scientific endeavors have yielded a suite of vaccines, pharmaceuticals, and antibodies, resulting in the preservation of countless lives (The 2023 Nobel Prize in Physiology or Medicine was awarded to Hungarian scientist Katalin Karikó and American scientist Drew Weissman for their revolutionary invention to develop an effective mRNA vaccine to prevent Covid-19). Nevertheless, the fight against COVID-19 continues as immune escape variants of concern such as Delta and Omicron emerge. To develop more effective treatments and to elucidate the side effects caused by vaccines and therapeutic agents, a deeper understanding of the molecular interactions of SARS-CoV-2 with them and human cells is required. With special interest in computational approaches, in this we will focus on the structure of SARS-CoV-2 and the interaction of its spike protein with human angiotensin-converting enzyme-2 (ACE2) as a prime entry point of the virus into host cells. In addition, other possible viral receptors will be considered. The fusion of viral and human membranes and the interaction of the spike protein with antibodies and nanobodies will be discussed, as well as the effect of SARS-CoV-2 on protein synthesis in host cells.

Laser cooling of atoms containing antimatter

Phys. Rev. Lett. 132, 083402

The cloud of exotic atoms made up of matter and antimatter was cooled by more than 200 degrees in a controlled manner. The international team of scientists from the AEgIS experiment working at CERN has made the first experimental demonstration of laser cooling of positronium atoms. This is anothe...

Temperature dependence of chromatic dispersion for hygroscopic liquids

Using a modified Abbe refractometer, the chromatic dispersion and temperature dependence of the refractive index of a range of hygroscopic liquids was measured from 390 to 1070 nm for temperatures from 1 to 45°C. To obtain an analytical formula, the Sellmeier formula was fitted to the experimenta...

Topological phase diagram of Eu-based compounds

Combined experimental, theoretical, and computational investigations have identified the origin of outstanding magnetooptical and magnetotransport properties of EuCd2As2 and provided topological and magnetic phase diagrams for various classes of Eu-based compounds.
