NK cells also act as regulatory cells that modulate dendritic cell function and promote T cell responses.170 In tumor microenvironments, NK cells produce the chemokines CCL5 and XCL1, which facilitates recruitment of cDC1 to tumor sites, where cDC1 cells take up tumor antigens and cross present the antigens to tumor-specific CD8 T cells to promote antitumor T cell responses.171. Here, CD8A is linked to neoplasm.
