The identification of 10 macrophage‐associated molecular features, including AHI1, BCL2A1, CD14, HSPA1B, MBNL2, MLLT6, RABEP1, SDC4, SGK1 and UFSP2, unveils a complex molecular landscape in the context of subarachnoid haemorrhage (SAH). The gene discussed is UFSP2; the disease is subarachnoid hemorrhage.
