Pathogen-Associated Molecular Pattern (PAMP) Recognition

Understanding infectious diseases and autoimmune disorders as well as developing new therapeutic and diagnostic methods depend heavily on precise identification and analysis of Pathogen-Associated Molecular Patterns (PAMPs) and their interactions with Pattern Recognition Receptors (PRRs). Creative Diagnostics delivers complete PAMP identification analysis through advanced near-infrared microarray protein chip technology. We provide services aimed at supporting basic research activities and making scientific findings available for clinical application.

Our Services

1. Deciphering PAMP Recognition Mechanisms for Drug Target Identification:

• Application: Use near-infrared fluorescence labeling to achieve precise analysis of interactions between PRRs such as TLR9 and MDA5 and pathogen nucleic acids like DNA and RNA. Through this service researchers can discover potential drug targets to control these vital binding interactions.
• Benefit: By understanding the early immune activation phases in detail scientists can create specific therapies for infectious and inflammatory diseases.
• Example: Discover the key PRR-PAMP interactions crucial to bacterial infection pathogenesis as a foundation for creating innovative antibacterial treatments.
• Further Application: Utilize advanced protein microarray technology to study how PAMP-induced signaling complexes like amyloid-DNA complexes activate immune cells such as plasmacytoid dendritic cells and trigger type I interferon responses. Through this methodology researchers gain insight into autoimmune disease mechanisms and identify new therapeutic possibilities.

2. Functional Characterization of Protein-Nucleic Acid Complexes for Therapeutic and Vaccine Development:

• Application: Perform real-time kinetic analysis and stability characterization of protein-nucleic acid complexes on protein chip surfaces using high-resolution laser confocal scanning technology. This enables researchers to achieve an in-depth comprehension of how complexes form and separate.
• Benefit: Conduct assessments of both how well these complexes protect nucleic acids and their effectiveness in delivering substances to endosomes. The analysis results form a vital basis for the advancement of delivery techniques applied to nucleic acid-based therapeutics and immunizations.
• Example: Study how effectively a specific protein protects therapeutic RNA from degradation and improves its cellular absorption to boost treatment results.

3. High-Throughput Screening for Novel Biomarkers and Therapeutic Targets in Autoimmune Diseases:

• Application: Perform comprehensive, high-throughput targeted mapping of protein-nucleic acid interactions using functional silicon membrane substrates. This methodology improves detection sensitivity to enable scientists to discover both weak and fleeting interactions.
• Benefit: Discover new regulatory molecules including RNA-binding proteins that are involved in autoimmune disease processes. Medical professionals can find early diagnostic biomarkers while discovering new therapeutic targets for disease treatment through this approach.
• Example: Analyze serum samples from lupus patients to discover specific protein-nucleic acid interaction profiles which can act as diagnostic markers or uncover new disease-driving pathways.

Technical Platform Advantages

Significance in Autoimmune Disease Research

Abnormal nucleic acid complexes (such as DNA-amyloid fibrils) can activate pDC cells to produce type I interferons, breaking immune tolerance and inducing antinuclear antibodies, which are directly related to diseases like systemic lupus erythematosus (SLE). Precise detection of abnormal interactions between PRRs and self-nucleic acids can reveal disease mechanisms and screen for intervention targets. For example:

• ADAR1 RNA editing deficiency leads to endogenous dsRNA being recognized by MDA5, triggering autoinflammation
• Decreased expression of hnRNP UL1 promotes excessive activation of the NF-κB pathway, related to rheumatoid arthritis
