Attenuated Subcomponent Vaccine Design Targeting the SARS-CoV-2 Nucleocapsid Phosphoprotein RNA Binding Domain: In Silico Analysis.

Attenuated Subcomponent Vaccine Design Targeting the SARS-CoV-2 Nucleocapsid Phosphoprotein RNA Binding Domain: In Silico Analysis. J Immunol Res. 2020;2020:2837670 Authors: Chukwudozie OS, Chukwuanukwu RC, Iroanya OO, Eze DM, Duru VC, Dele-Alimi TO, Kehinde BD, Bankole TT, Obi PC, Okinedo EU Abstract The novel coronavirus disease (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has previously never been identified with humans, thereby creating devastation in public health. The need for an effective vaccine to curb this pandemic cannot be overemphasized. In view of this, we designed a subcomponent antigenic peptide vaccine targeting the N-terminal (NT) and C-terminal (CT) RNA binding domains of the nucleocapsid protein that aid in viral replication. Promising antigenic B cell and T cell epitopes were predicted using computational pipelines. The peptides "RIRGGDGKMKDL" and "AFGRRGPEQTQGNFG" were the B cell linear epitopes with good antigenic index and nonallergenic property. Two CD8+ and Three CD4+ T cell epitopes were also selected considering their safe immunogenic profiling such as allergenicity, antigen level conservancy, antigenicity, peptide toxicity, and putative restrictions to a number of MHC-I and MHC-II alleles. With these selected epitopes, a nonallergenic chimeric peptide vaccine incapable of inducing a type II hypersensitivity reaction was constructed. The molecular interaction between the ...

Pathology Autopsy and Mortuary Services have been front and center in the severe acute respiratory syndrome coronavirus 2 (SARS-Co-V-2) pandemic. The sheer number of fatalities from the pandemic have been unlike any other in recent memory and needed the rapid creation of new protocols and paradigms to manage the situation. This required rapidly escalating mortuary capacity to manage the increased fatalities from the pandemic with the establishment of lines of communication and networking with governmental entities, institution of new policies for patient flow, and implementation of worker infection control and well-being p...

The global pandemic of COVID-19 disease caused by infection with the SARS-CoV-2 coronavirus, has produced an urgent requirement and search for improved treatments while effective vaccines are developed. A strategy for improved drug therapy is to increase levels of endogenous reactive metabolites for selective toxicity to SARS-CoV-2 by preferential damage to the viral proteome. Key reactive metabolites producing major quantitative damage to the proteome in physiological systems are: reactive oxygen species (ROS) and the reactive glycating agent methylglyoxal (MG); cysteine residues and arginine residues are their most susce...

Purpose of review The Coronavirus Disease 2019 (COVID-19) pandemic caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a global health threat associated with major socioeconomic disruptions. Understanding on the transmission characteristics of SARS-CoV-2 is crucial for optimizing preventive strategies. Recent findings SARS-CoV-2 can be transmitted efficiently between persons through respiratory droplets and direct and indirect contact. The significance of airborne droplet nuclei in SARS-CoV-2 transmission in the community setting is less clear. SARS-CoV-2 RNA and live viral particles ma...

Since December 2019, the coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 has spread worldwide, affecting millions of people and leaving hundreds of thousands dead, mostly older adults. Recently, the five main geriatric journals in the United States have joined together to produce a common text denouncing the ageism that manifested itself during the first wave of the pandemic. This text proposes four recommendations: 1) to make clinical research more inclusive for all ages, 2) to involve geriatricians and gerontologists in institutional decisions, 3) to inform policy and funding by taking into account the specific ...

Abstract The novel human coronavirus-2 (HCoV-2), called SARS-CoV-2, is the causative agent of Coronavirus Induced Disease (COVID-19) and has spread causing a global pandemic. Currently, there is no vaccine to prevent infection nor any approved drug for the treatment. The development of a new drug is time-consuming and cannot be relied on as a solution in combatting the immediate global challenge. In such a situation, the drug repurposing becomes an attractive solution to identify the potential of COVID-19 treatment by existing drugs, which are approved for other indications. Here, we review the potential use of ra...
