Functional Genomics Service for Immune System

Combining large-scale analyses of immune variability with accompanying functional information can advance future research into immune-mediated diseases and understand how variation among individuals underlies disease mechanisms. CD Genomics provides specialized functional genome sequencing and analysis services to advance basic immunology research and potential applications.

Introduction to Functional Genomics

Functional genomics deals with genes, functions, and their interactions. High-throughput technologies are often used to conduct research in this area, generating a wealth of data. Disease susceptibility variants revealed through genome-wide association studies (GWAS) are quantitative trait loci (QTL), which provide causal information on intermediate traits between the genome and disease. A comprehensive understanding of these traits will facilitate the development of genomic function studies.

Understanding Immune Function by HFGP

The Human Functional Genomics Project (HFGP) aims to identify genetic and non-genetic host factors that determine inter-individual variability in immune responses. Many studies based on immune functional genomics have been carried out to unravel the molecular basis of immune diversity.

  • Functional Genomics of Type 1 Diabetes
    Type 1 diabetes (T1D) is a common chronic autoimmune disease characterized by the destruction of insulin-producing beta cells in the pancreas. Peripheral blood samples from T1D patients and healthy human cohorts are deeply immunophenotyped using cell subpopulation composition and post-stimulation cytokine production as a proxy for immune function. It is found that CCR5+ regulatory T cells are associated with T1D through the CCR region, suggesting common genetic regulation and 15 loci are identified that affect the immune response of patients.

  • Functional Genomics of Cytokines
    Cytokines are key modulators of the immune response to invading pathogens. Changes in cytokine responses determine susceptibility to infectious diseases as well as autoimmune and inflammatory diseases. By comparing cytokine and genetic data and genome-wide cytokine quantitative trait locus (cQTL) mapping in healthy adults of East African ancestry and Western European ancestry, 80 independent suggestive loci and one genome-wide significant locus (TBC1D22A) on chromosome 22 are identified to be associated with immune responses against microorganisms. In addition, SNP rs12169244 is found to be associated with the release of IL-1b following Salmonella enteritidis stimulation.

Our Services

Functional genomics is the study of how genes and intergenomic regions contribute to different biological processes. Functional genomics for immune system is useful for identifying the mechanisms of action of disease-associated variants and the underlying mechanisms of complex diseases, leading to advances in translating genetic discoveries into the clinic.

CD Genomics has been engaged in immunomics research for many years and has a professional sequencing and related genotyping platform to provide professional, efficient, and large-scale functional genomics services and GWAS services to analyze the pathogenesis of a variety of diseases and develop potential therapies, including but not limited to the following fields.

  • Infectious Diseases
  • Tumor
  • Autoimmune Diseases
  • Transplantation

In addition, CD Genomics has a professional data analysis team that can help clients analyze genomic data to process large-scale data and to identify potential disease-causing variants and disease-causing genes in autoimmunity.
