Next, we analyzed the correlation between CD24 expression level and the abundance of tumor-infiltrating lymphocytes (TILs), including activated CD8+ T cells, activated CD4+ T cells, natural killer cells, activated dendritic cells, macrophages, monocytes, and neutrophils, using the TISIDB database (http://cis.hku.hk/TISIDB/) (accessed on 1 March 2023) [31]. Here, CD8A is linked to neoplasm.
