Overview
This lecture summarizes the Fourth World Immunology Day 2025 International Conference, focusing on the latest research and innovations in immunology and infectious diseases, including vaccine technology, pathogen surveillance, translational science, and immunotherapy.
Conference Overview & Opening
- The conference gathered global experts to discuss immunological frontiers in infectious diseases, from molecular mechanisms to clinical applications.
- Key address topics: vaccine development, antibody engineering, bioinformatics, and the translation of research into health policy.
- A real-time PCR workshop on gene expression was highlighted as a pre-conference event.
Emerging Infectious Diseases (EIDs) & Vaccine Technology
- EIDs frequently originate from animals (zoonotic spillover), driven by global travel, climate change, and viral mutation.
- Rapid mutation and antigenic variability challenge vaccine development.
- Modern platforms (mRNA, viral vector, nanoparticle vaccines) enable faster, broader, and more targeted immune responses.
- AI, cryo-EM, and systems immunology accelerate epitope prediction and vaccine optimization.
Pathogen Studies and Antibody Development
- Leptospirosis, a major tropical threat, was explored through bacterial protein virulence factor screening using yeast models.
- Isolation and analysis of monoclonal antibodies enable identification of broadly neutralizing antibodies for influenza and other pathogens.
- Structure-based antigen design (e.g., for universal coronavirus or influenza vaccines) aims for broad-spectrum protection.
Translational Immunology & Public Health Implementation
- Gut microbiota and probiotics play a role in immune regulation and autoimmunity.
- Translational research bridges lab findings with clinical practice and public health policy.
- Hospital innovation and entrepreneurship improve pediatric immunotherapy and allergy treatment services.
Innovations in Diagnostics, Bioinformatics, and Surveillance
- Bioinformatics aids in rapid drug and vaccine discovery, especially for emerging threats like Nipah virus.
- Global surveillance systems (GISRS, AI-driven prediction) help monitor pathogen evolution and prepare for epidemics.
- BSL-4 labs are vital for high-risk pathogen research.
Oral & Poster Presentations—Selected Highlights
- Presentations covered checkpoint inhibitor biomarkers in cancer, epitope mapping for SARS-CoV-2 variants, oral microbiome and focal infection, and immunoglobulin profiles in special populations.
- Research demonstrated the link between immunological markers, disease progression, and novel therapies.
Key Terms & Definitions
- Emerging Infectious Diseases (EIDs) — new/reappearing infections often originating from animals.
- Antigenic drift/shift — minor/major genetic changes in pathogens leading to immune escape.
- mRNA Vaccine — delivers genetic code for antigens to stimulate immunity.
- Viral Vector Vaccine — uses modified viruses to deliver pathogen genes.
- Nanoparticle Vaccine — presents antigens on engineered particles to boost immune recognition.
- Cryo-EM — imaging method that reveals pathogen structure at near-atomic resolution.
- Systems Immunology — analysis of immune responses using large integrated datasets.
- Broad-spectrum Vaccine — targets conserved regions to protect against many strains.
Action Items / Next Steps
- Review assigned readings on vaccine platforms and immunological surveillance.
- Prepare for a follow-up quiz covering key concepts from the conference.
- Continue research projects and submit oral/poster abstracts for next year’s event.
