Insights
The novel coronavirus disease 2019 (COVID-19) is a highly infectious virus with human-to-human transmission. Research is urgently needed to understand its pathogenesis and identify therapeutic targets for disease control.
Area of Science:
- Virology
- Emerging Infectious Diseases
- Public Health
Background:
- The World Health Organization announced a novel coronavirus, COVID-19, on December 31, 2019, in Wuhan.
- COVID-19 is the third highly infective coronavirus (CoV) identified, with a 2% mortality rate, lower than MERS-CoV and SARS-CoV.
- Coronaviruses are positive-stranded RNA viruses prevalent in mammals, with the 2019-nCoV utilizing the ACE2 receptor, similar to SARS-CoV.
Purpose of the Study:
- To provide an overview of the biological characteristics of coronaviruses.
- To explain the pathogenesis of COVID-19.
- To focus on therapeutic approaches and suggest potential targets for treating and monitoring this emerging zoonotic disease.
Main Methods:
- Literature review of common biological criteria of CoVs.
- Analysis of pathogenesis mechanisms, including viral entry via ACE2.
- Exploration of potential therapeutic strategies and targets.
Main Results:
- Human-to-human transmission of 2019-nCoV has been confirmed.
- Structural proteins play a key role in viral release and host cell budding.
- No licensed antiviral drugs or vaccines are currently available for COVID-19.
Conclusions:
- There is an urgent need for extensive research into CoV infections.
- Understanding transmission routes, pathogenesis, and diagnosis is crucial for disease control.
- Identifying therapeutic targets is essential for managing and monitoring emerging zoonotic diseases like COVID-19.
Abstract:
On December 31, 2019, a novel coronavirus, being the third highly infective CoV and named as coronavirus disease 2019 (COVID-19) in the city of Wuhan, was announced by the World Health Organization. COVID-19 has a 2% mortality rate, is known as the third extremely infective CoV infection, and has a mortality rate less than MERS-CoV and SARS-CoV. The CoV family comprises a chief number of positive single-stranded ss (+) RNA viruses that are recognized in mammals. The 2019-nCoV patients showed that the angiotensin-converting enzyme II (ACE2) was the same for SARS-CoV. Structural proteins have an essential role in virus released and budding to various host cells. Notably, evidence indicated human-to-human transmission, along with several exported patients of virus infection worldwide. Nowadays, no licensed antivirals drugs or vaccines for being utilized against these coronavirus infections are recognized. There is an urgent requirement for an extensive research of CoV infections to disclose the route of extension, pathogenesis, and diagnosis and then to recognize the therapeutic targets to facilitate disease control and surveillance. In this article, we present an overview of the common biological criteria of CoVs and explain pathogenesis with a focus on the therapeutic approach to suggest potential goals for treating and monitoring this emerging zoonotic disease.

Conjugated Proteins
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
