SIRPA and central nervous system cancer: Bioinformatic analyses of scRNA seq datasets of eighteen glioma patients (two with low-grade glioma, eleven with newly diagnosed glioblastoma, and five with recurrent glioblastoma) demonstrate that SIRPA is expressed in myeloid cells (Figure 2b), and multiplex imaging shows P2RY12+ microglia also express SIRPα (Figure 2c) [18,19].
