The newly discovered SARS-CoV-2 Omicron variant B.1.1.529 is a Variant of Concern (VOC) announced by the World Health Organization (WHO). It's becoming increasingly difficult to keep these variants from spreading over the planet. The fifth wave has begun in several countries because of Omicron variant, and it is posing a threat to human civilizatio...

The spike protein comprises one of the main structural components of SARS-CoV-2 because it is directly involved in the infection process and viral transmission, and also because of its immunogenic properties, as an inducer of the protective antibodies production and as a vaccine component. The occurrence of mutations in this region or in other the ...

The world health organization has announced that SARS-CoV-2 Omicron variant (B.1.1.529), including the three versions; 21K (BA.1), 21L (BA.2) and 21M (BA.3) as a variant of concern (VOC) on November 2022. In this study, we used the specialized computational platforms to predict the stability and flexibility of the spike protein of Omicron. The aim ...

Coronavirus disease 2019 caused by the novel human severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is currently a major threat to public health worldwide. To deal with the needs of vaccine, we developed four DNA vaccine candidates against SARS-CoV-2, based on the full-length spike (S) or truncated S protein. Following mice vaccination,...

Recurrent waves of COVID19 remain a major global health concern. Repurposing either FDA-approved or clinically advanced drug candidates can save time and effort required for validating the safety profile and FDA approval. However, the selection of appropriate screening approaches is key to identifying novel candidate drugs with a higher probability...

The challenge continues globally triggered by the absence of an approved antiviral drug against COVID-19 virus infection necessitating global concerted efforts of scientists. Nature still provides a renewable source for drugs used to solve many health problems. The aim of this work is to provide new candidates from natural origin to overcome COVID-...

Enveloped viruses such as Coronaviridae (CoV) enter the host cell by fusing the viral envelope directly with the plasma membrane (PM) or with the membrane of the endosome. Replication of the CoV genome takes place in membrane compartments formed by rearrangement of the endoplasmic reticulum (ER) membrane network. Budding of these viruses occurs fro...

Since December 2019, the deadly novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused the current COVID-19 pandemic. To date, vaccines are available in the developed countries to prevent the infection of this virus; however, medicines are necessary to help control COVID-19. Human coronavirus 229E (HCoV-229E) causes the commo...

Rice black-streaked dwarf virus (RBSDV) is an important reovirus that infects both plants and its transmission vector small brown planthopper, causing severe crop loss. High affinity binding between RBSDV P10 and PI(3,5)P2 lipid layer was measured using biolayer interferometry (BLI). Subcellular co-localization of PI(3,5)P2 and RBSDV P10 was observ...
