NF2 and meningioma: However, Teranishi et al. (2023) also noted NF2-SWN meningioma were of a more ‘immunogenic’ subtype than sporadic meningioma, finding that NF2-SWN meningioma had greater CD45 + staining by immunohistochemistry, higher PTPRC gene expression by bulk RNA-seq, and more myeloid cells in NF2-SWN meningioma when deconvolved by xCell [47].
