CX3CR1 and neoplasm: In silico and histological analyses revealed that samples with high CD200R1 expression contained more tumor-infiltrating immune cells, while cyto-chemokine networks (CX3CR1, CXCL9, IFNG) and immuno-receptor and adaptor proteins (DOK2, TYROBP, CD300LF) were likely to contribute to antitumor cell immunity in tumors with high CD200R1 expression.
