static reviewed map

Curated external IDs add pathway and protein context around Atlas content. They do not update the graph automatically and they are not patient-specific interpretation.

Inflammatory Role

Raises systemic inflammatory tone and supports acute phase proteins and TH17 conditions.

Regulatory Role

Can support tissue repair and B cell maturation when tightly time-limited.
