AI Article Synopsis

  • Researchers identified GAPDH from Edwardsiella tarda as a potential vaccine candidate due to its effectiveness against infections.
  • The study involved sequencing the gene encoding GAPDH and producing it in large amounts using E. coli.
  • Immunizing Japanese flounder with recombinant GAPDH demonstrated significant protection against E. tarda, supporting its use in vaccine development.

Article Abstract

Thirty-seven kilodalton glyceraldehyde-3-phosphate dehydrogenase (GAPDH) of Edwardsiella tarda was suggested to be an effective vaccine candidate against E. tarda infection in previous research. For developing a vaccine, obtaining GAPDH in large quantities is necessary. In this study, we determined the complete nucleotide sequence of the gene that encodes GAPDH of E. tarda, and overexpressed the GAPDH of E. tarda by using the Escherichia coli expression system. We immunized Japanese flounder with recombinant GAPDH (rGAPDH) and evaluated its vaccine efficacy. Our results showed that rGAPDH effectively protected Japanese flounder from experimental E. tarda infection, and will contribute to the development of a vaccine against E. tarda.

India's National COVID Vaccination Program recommended vaccination of children ages 6-12 years in April 2022. This study assessed vaccine acceptance among mothers to better understand potential barriers and facilitators of national acceptance of pediatric coronavirus disease 2019 (COVID-19) vaccination. Qualitative data were collected through three focus group discussions (FGDs) with mothers who had children younger than 12 years of age; FGD-1 was composed of mothers who worked at a tertiary medical center in India, whereas FGD-2 and FGD-3 were composed of mothers who sought care at urban and rural community health centers.

Objective: This review synthesizes qualitative research about the experiences of parental caregivers enhancing their children's health after making the decision to not vaccinate their preschool children. This review aims to help health care providers understand the parental work involved in caring for under-vaccinated or unvaccinated children.

Introduction: Much of the current qualitative research literature about parents who are vaccine-hesitant or who decide not to vaccinate their children focuses on parental perceptions about the safety and efficacy of vaccines and decision-making.

Department of Global and Public Health, Epidemiology, Biostatistics and Prevention Institute, WHO Collaborating Centre for Travellers' Health, Centre of Competence for Military Medicine Biology, University of Zürich, Switzerland.

Background: The rapid development and distribution of mRNA COVID-19 vaccines has been essential in containing the SARS-CoV-2 epidemic around the globe. For ongoing and future immunization campaigns globally, there is a need to evaluate the impact of population demographics such as age and sex, on vaccine efficacy and safety.

Methods: This systematic review (PROSPERO ID CRD42023328245) conducted according to PRISMA guidelines evaluates the impact of age and sex on the safety and efficacy of the mRNA COVID-19 vaccinations administrated in 15 studies that were chosen according to strict criteria.

Lipid nanoparticles deliver DNA-encoded biologics and induce potent protective immunity.

Mol Cancer

Department of Medicine, Section of Epidemiology and Population Sciences, Dan L Duncan Comprehensive Cancer Center, Baylor College of Medicine, Houston, TX, 77030, USA.

Lipid nanoparticles (LNPs) for mRNA delivery have advanced significantly, but LNP-mediated DNA delivery still faces clinical challenges. This study compared various LNP formulations for delivering DNA-encoded biologics, assessing their expression efficacy and the protective immunity generated by LNP-encapsulated DNA in different models. The LNP formulation used in Moderna's Spikevax mRNA vaccine (LNP-M) demonstrated a stable nanoparticle structure, high expression efficiency, and low toxicity.

The emerging combination of chemotherapy and radionuclide therapy has been actively investigated to overcome the limitations of monotherapy and augment therapeutic efficacy. However, it remains a challenge to design a single delivery vehicle that can incorporate chemotherapeutics and radionuclides into a compact structure. Here, a chelator DOTA- or NOTA-modified Evans blue conjugated camptothecin molecule (EB-CPT) nanoprodrug was synthesized, which could self-assemble into nanoparticles due to its inherent amphiphilicity.
