CD4 and neoplasm: To assess the expression and impact of PGLYRP1 on the PDAC immune compartment, the stroma cell populations expressing PGLYRP1 were analysed using the previously mentioned scRNA-seq dataset.21 Neutrophils, monocytes, CD4+ and CD8+ T cells were found to express Pglyrp1, although in a lower proportion compared with tumour cells (online supplemental figure S4A, B).
