Note that the HMGB1 protein belongs to the DAMPs released by transformed cells and is involved in the myeloid-derived cell chemoattraction and TREM1-activation.9 Next, we performed profiling of the human myeloid-derived cell markers in patient-derived glioblastoma xenolines (PDX) using RNA-seq technique. This evidence concerns the gene TREM1 and glioblastoma.
