Viruses, Vol. 16, Pages 665: Exploring the Antiviral Potential of Esters of Cinnamic Acids with Quercetin
o Manzin Giuseppina Sanna Severe acute respiratory syndrome-related Coronavirus 2 (SARS-CoV-2) has infected more than 762 million people to date and has caused approximately 7 million deaths all around the world, involving more than 187 countries. Although currently available vaccines show high efficacy in preventing severe respiratory complications in infected patients, the high number of mutations in the S proteins of the current variants is responsible for the high level of immune evasion and transmissibility of the virus and the reduced effectiveness of acquired immunity. In this scenario, the development of safe...

rco Malcolm Hedgcock Cecilia T. Costiniuk Mark Hull Marianne Harris Marc G. Romney Julio S. G. Montaner Zabrina L. Brumme Mark A. Brockman People living with HIV (PLWH) can exhibit impaired immune responses to vaccines. Accumulating evidence indicates that PLWH, particularly those receiving antiretroviral therapy, mount strong antibody responses to COVID-19 vaccines, but fewer studies have examined cellular immune responses to the vaccinations. Here, we used an activation-induced marker (AIM) assay to quantify SARS-CoV-2 spike-specific CD4+ and CD8+ T cells generated by two and three doses of COVID-19 v...

Viruses, Vol. 16, Pages 659: Design and Application of Biosafe Coronavirus Engineering Systems without Virulence
ingxin Ma In the last twenty years, three deadly zoonotic coronaviruses (CoVs)—namely, severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome coronavirus (MERS-CoV), and SARS-CoV-2—have emerged. They are considered highly pathogenic for humans, particularly SARS-CoV-2, which caused the 2019 CoV disease pandemic (COVID-19), endangering the lives and health of people globally and causing unpredictable economic losses. Experiments on wild-type viruses require biosafety level 3 or 4 laboratories (BSL-3 or BSL-4), which significantly hinders basic virological r...

Determination of optimum levels of binding antibody units (BAU) of new quantitative chemiluminescent immuno-assay (CLIA) in COVID-19 vaccinated volunteer blood donors
This study was undertaken to determine optimum levels of binding antibody units (BAU/ml) in new quantitative chemiluminescent assay (CLIA) that corresponded to neutralizing potential (30% inhibition) of sVNT assay. Methods: Ninety-one blood samples were analyzed by CLIA and sVNT assays. Test samples (n=75) were collected from blood donors post-2nd vaccination dose, while control samples (n=16) were archived pre-COVID donor samples. (Source: Transfusion and Apheresis Science)

The contributions of vaccination and natural infection to the production of neutralizing antibodies against the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) prototype strain and variants
The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a novel coronavirus responsible for the coronavirus disease 2019 (COVID-19) global pandemic [1-3]. As the pandemic progressed, new, more transmissible but less virulent variants, like the Omicron variant, emerged and became more dominant, further reducing the mortality rate [4-8]. The World Health Organization (WHO) eventually declared that the COVID-19 pandemic no longer constitutes a public health emergency of international concern on May 2023 [9].

Impact of SARS-CoV-2 vaccines on Covid-19 incidence and mortality in the United States
ConclusionsAssociations between complete vaccination rates and COVID-19 incidence and mortality appeared to vary with shifts in the dominant variant, perhaps due to variations in vaccine efficacy by variant or to waning vaccine immunity over time. Vaccine boosters were associated with notable protection against Omicron disease and mortality. (Source: PLoS One)

Role of the RAAS in mediating the pathophysiology of COVID-19
Pharmacol Rep. 2024 Apr 23. doi: 10.1007/s43440-024-00596-3. Online ahead of print.ABSTRACTThe renin-angiotensin-aldosterone system (RAAS) holds a position of paramount importance as enzymatic and endocrine homeostatic regulator concerning the water-electrolyte and acid-base balance. Nevertheless, its intricacy is influenced by the presence of various complementary angiotensins and their specific receptors, thereby modifying the primary RAAS actions. Angiotensin-converting enzyme 2 (ACE2) acts as a surface receptor for SARS-CoV-2, establishing an essential connection between RAAS and COVID-19 infection. Despite the recurri...

Vaksinen øling under koronapandemien blant unge med etnisk minoritetsbakgrunn i Oslo øst – en kvalitativ studie
Tidsskr Nor Laegeforen. 2024 Apr 8;144(5). doi: 10.4045/tidsskr.23.0690. Print 2024 Apr 23.ABSTRACTBACKGROUND: Few studies have been conducted on young people's attitudes to the COVID-19 vaccine during the pandemic. We wished to examine how young people with an ethnic minority background decided whether to have the COVID-19 vaccine, based on the concept of vaccine hesitancy. Vaccine hesitancy involves uncertainty with regard to vaccination, irrespective of the decision taken.MATERIAL AND METHOD: Fourteen qualitative in-depth interviews with young people aged 16-25 years with an ethnic minority background and from the east ...

CovEpiAb: a comprehensive database and analysis resource for immune epitopes and antibodies of human coronaviruses
Brief Bioinform. 2024 Mar 27;25(3):bbae183. doi: 10.1093/bib/bbae183.ABSTRACTCoronaviruses have threatened humans repeatedly, especially COVID-19 caused by SARS-CoV-2, which has posed a substantial threat to global public health. SARS-CoV-2 continuously evolves through random mutation, resulting in a significant decrease in the efficacy of existing vaccines and neutralizing antibody drugs. It is critical to assess immune escape caused by viral mutations and develop broad-spectrum vaccines and neutralizing antibodies targeting conserved epitopes. Thus, we constructed CovEpiAb, a comprehensive database and analysis resource ...
