NF2 and neoplasm: In terms of detailed cell type of expression based on the deconvoluted data, myeloid (macrophage; p = 0.02, M2; p = 0.005, monocytes; p = 0.002, neutrophils; p = 0.03, conventional dendritic cell (CDC); p = 0.007, plasmacytoid dendritic cell (PDC); p = 0.001) and lymphoid cells (B-cells; p = 0.02, CD4+ memory T-cells; p = 0.002, gamma delta T cell (tgd cells); p = 0.04) expressed higher in the tumour in NF2 patients than sporadic NF2-altered meningiomas (Fig. 3E–G).
