CHI3L2 and neoplasm: To estimate the relevance of CHI3L2 and diverse immune cell markers, we used the TIMER platform to investigate correlations between CHI3L2 levels and markers of diverse immune cells, included monocytes, TAMs (tumor-associated macrophages), M1 and M2 macrophages, Tregs (regulatory T cells), exhausted T cells, CD8+ T cells, T cells (general), B cells and neutrophils in GBM and LGG (Table 4).
