The Allen Immunology domain map for aging and immune memory is anchored by a recent multi-omic healthy-adult atlas, but most mechanistic cells remain frontier regions rather than settled territory. The mature core is the descriptive layer: blood-accessible age trajectories, CD8 memory-state remodeling, and the broad inflammaging vocabulary. What is still thin is the bridge from those descriptive states to durable, tissue-resolved causal mechanisms.
Two cells currently look comparatively mature (2 total): atlas-scale profiling and CD8 memory-state biology. A second tier of 5 cells has enough literature to support stable subfield labels but not enough convergence to collapse key disputes, especially around TRM maintenance, helper-memory failure, vaccine durability, and trained immunity.
The highest-value white space sits in 7 frontier cells where longitudinal intervention data, tissue sampling, and heterogeneity-aware study design are still sparse. Those gaps suggest the next SciDEX downstream work should emphasize cross-tissue atlas expansion, intervention-linked memory readouts, and neuroimmune-interface studies that explicitly connect peripheral memory compartments to age-associated CNS inflammation.
