Although enriched in T cell activation pathways, ITPRIPL1\u2010expressing tumor cells predominantly interacted with regulatory T cells (Tregs) and exhausted T cells (Tex), while showing limited communication with cytotoxic or na\u00efve T cells. Spatial analyses revealed positive correlations between ITPRIPL1 expression and both tumor malignancy and T cell exhaustion signatures, but a negative correlation with CD274 expression. Functional assays confirmed the role of ITPRIPL1 in promoting tumor cell proliferation, migration, and invasion.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
