Background of Influenza
Caused by specific viruses, influenza (or the flu) is a very contagious condition that mainly affects the respiratory system and comes on suddenly. Influenza viruses are notorious for their significant genetic variability, which allows them to constantly evade host immunity, leading to annual epidemics and unpredictable pandemics. Common signs are a quick start of fever, cough, a sore throat, body aches, headaches, and feeling tired. Complications can range from bacterial pneumonia and acute respiratory distress syndrome (ARDS) to exacerbation of chronic medical conditions, especially in high-risk populations like the elderly, young children, pregnant individuals, and those with compromised immune systems.
Influenza viruses belong to the Orthomyxoviridae family, mainly categorized into A, B, C, and D types according to the antigenic characteristics of their nucleoprotein and matrix protein. For influenza A virus (IAV), subtypes are distinguished by surface components, hemagglutinin (H) and neuraminidase (N), which are essential for viral entry and release. This classification system reflects their genetic variability and distinct epidemiological patterns.

Challenges in Influenza Treatment
Current influenza treatment strategies primarily focus on vaccination for prevention and anti-influenza drugs for therapeutic intervention, alongside symptomatic relief. Despite existing strategies, significant challenges persist in influenza treatment:
-
Antiviral Resistance: The rapid evolution of influenza viruses can lead to the emergence of drug-resistant strains, limiting the effectiveness of current antiviral therapies.
-
Narrow Therapeutic Window: Antivirals are most effective when administered very early in the infection, often before diagnosis is confirmed.
-
Systemic Side Effects: Some antiviral drugs can have undesirable side effects, impacting patient compliance and suitability for certain populations.
-
Delivery Limitations: Conventional drug delivery methods may face challenges in achieving optimal drug concentrations at the site of infection (e.g., lungs) while minimizing systemic exposure.
-
Vaccine Efficacy Fluctuations: The need for annual vaccine reformulation due to antigenic drift and shift can lead to varying levels of effectiveness each season.
Creative Biolabs addresses these critical challenges by developing innovative lipid-based drug delivery systems. Our advanced formulations offer solutions for enhanced drug encapsulation, targeted delivery to respiratory cells, improved stability, and the potential to bypass resistance mechanisms, paving the way for more effective and safer influenza treatments.
How Creative Biolabs' Lipid-Based Drug Delivery Systems Can Assist Your Project

Creative Biolabs' lipid-based drug delivery systems provide transformative solutions for overcoming the inherent challenges in influenza therapeutics and vaccine development. Our expertise in designing and optimizing liposomes and lipid nanoparticles (LNPs) enables enhanced project outcomes through the precise execution of various influenza virus suppression strategies:
-
Advanced Vaccination Strategies: Our lipid-based drug delivery systems are integral to developing next-generation influenza vaccines.
Viral Antigen Vaccination Strategies
We utilize LNPs to encapsulate and deliver viral antigens, enhancing their stability and immunogenicity. This approach ensures more effective presentation of antigens to the immune system.
Inactivated Influenza Virus Strategies
LNPs can serve as sophisticated carriers for inactivated influenza viruses, improving their stability and allowing for controlled release. This enhances the vaccine's ability to elicit a robust immune response while maintaining the safety profile of inactivated vaccines.
mRNA Vaccines Strategies
Our cutting-edge LNP technology is optimized for the stable and efficient delivery of mRNA encoding influenza viral proteins. By allowing in-vivo antigen production that mimics natural infection, this method strongly stimulates both antibody and cellular immunity, marking a significant improvement in vaccine technology.

Potent Gene Silencing Strategies: Creative Biolabs leverages lipid-based delivery to enable targeted gene silencing, offering novel anti-influenza approaches. The group of silencers includes:
-
Antisense oligonucleotides (ASO)
-
Ribozymes
-
DNAzymes
-
Short interfering RNAs (siRNA)
-
MicroRNAs (miRNAs)
-
Short hairpin RNA (shRNAs)
-
Peptide nucleic acids (PNAs)
ASO Strategy
Our LNPs can effectively deliver ASOs, which are designed to bind to specific viral mRNA sequences, inhibiting viral protein synthesis. This allows for highly specific and targeted suppression of viral replication within infected cells.
siRNA Strategy
We facilitate the delivery of small interfering RNA (siRNA) molecules encapsulated within LNPs. Once delivered to cells, siRNA is incorporated into the RNA-induced silencing complex (RISC), targeting viral mRNAs in a sequence-specific manner. This triggers mRNA degradation, blocks the expression of essential viral proteins, and effectively halts viral spread.
DNAzymes Strategy
Our lipid delivery platforms can be engineered to transport DNAzymes, catalytic nucleic acid molecules that can cleave specific viral RNA targets. This provides another powerful mechanism for disrupting the viral life cycle by directly destroying viral genetic material.

Workflow for Lipid-Based Drug Delivery Systems Development for Influenza
Published Data
Recent research in Frontiers in Immunology provides compelling evidence for LNP effectiveness against influenza. The study showed LNPs loaded with an RNA adjuvant significantly reduced lung viral replication in mice infected with a matched flu strain, achieving very low viral levels by day 5 post-infection. This protection was linked to robust antibody and T-cell responses. Notably, the specific LNP ionizable lipid composition influenced the type of immune response and lung inflammation, highlighting its critical role in vaccine formulation.
