TREM2 molecule and its partial neighborhood: related molecules, publications, and authors. This sample of the MoleClue heterogeneous multilayer network shows the partial neighborhood of the TREM2 protein coding gene (some nodes and edges have been removed to reduce the clutter). Two molecules are connected with an edge if they are known to occur together in some biological context (e.g., participation in the same regulatory function). The weight on an edge corresponds to the strength of the association. An edge between a molecule and a publication exists when the publication mentions the molecule (e.g., in the title, abstract, or the list of keywords). An edge between a publication and an author expresses the authorship relation. All edges are directional but since all underlying relationships are symmetrical there is a pair of opposite directed edges between any two connected nodes
