Care Framework & Diagram
To truly understand the immune system, you need to read its genes, proteins, metabolites, and cells simultaneously
By the Editors Care Framework & Diagram
The Five Layers
Genome
What cards you hold — fixed for life.
Transcriptome
Which cards you’re playing right now — changes hourly.
Proteome
What effect those cards produced — closest to real function.
Metabolome
The energy and environment for playing the cards.
Immune Repertoire
How many different opponents you can recognize.
HLA Variability
Thousands of gene variants at each HLA site make everyone’s antigen-recognition ‘lens’ unique — the same vaccine can trigger very different antibody and T cell responses in different people.
Proteomics Aging Waves
A 3,000-person study found the body’s protein profile shifts in three sudden waves — at ages 34, 60, and 78. The wave at 60 is dominated by immune-related proteins.
TCR Diversity
An older adult’s T cell ‘recognition library’ holds only 10–20% of a young adult’s variety — the single most quantifiable marker of immune aging.
WHAT’S PRACTICAL TODAY
- For most people: standard blood tests plus an NK cell activity test cover the actionable indicators at reasonable cost.
- Full multi-omics profiling is mainly for research participants or elite health programs.
Frequently Asked Questions
What is the relationship between immunomics and 'precision medicine'?
Immunomics is the technical implementation foundation of precision medicine at the immune system level. HLA genomics is the genetic basis for individualized vaccines and neoantigen selection; TCR repertoire omics is the basis for tumor TIL therapy and ACT cell selection; proteomics is the biomarker source for immunotherapy response prediction. The landing of precision immune medicine depends on the maturation and popularization of immunomics technologies.
Does ordinary people need to do multi-omics testing?
Currently, full multi-omics testing is extremely expensive for ordinary healthy individuals (usually tens of thousands to hundreds of thousands of yuan per session), data interpretation is complex, and lacks sufficient 'normal value reference ranges' to guide individual daily decisions. For most people, a more practical starting point is: regular standard blood tests (hs-CRP, complete blood count lymphocyte proportion, vitamin D, fasting blood glucose) plus NK cell activity testing — these cover the most core actionable immune health indicators at acceptable cost.
Can TCR library sequencing tell me which viruses I've been infected with?
To a degree, but current database coverage is limited. For pathogens with large TCR-antigen pairing databases (flu virus, EBV, CMV, SARS-CoV-2), infection history can indeed be inferred from TCR library. But for most pathogens, TCR-antigen matching databases aren't yet comprehensive enough. As databases like VDJdb and MIRA continue expanding, this capability will grow stronger.
Is immunomics data helpful for early cancer detection?
Becoming a promising direction, but not yet in clinical routine. The presence of tumor-specific T cell clones in TCR library may precede imaging findings by months; certain cancer-related protein marker changes in plasma proteomics; and sustained NK cell activity decline (already proven correlated with elevated cancer risk). These findings are currently more used in research, needing large-scale prospective validation before becoming reliable clinical screening tools.
