In particular, the influence of stress on myeloid cells remains poorly explored. Here, we demonstrate that restraint stress accelerates hepatocellular carcinoma (HCC) progression through coordinated regulation of macrophages and neutrophils. Across sexes and strains, stressed mice exhibited enhanced tumor growth accompanied by marked neutrophil infiltration and elevated expression of neutrophil\u2010attracting chemokines. Integrative analyses combining single\u2010cell transcriptomics and in\u00a0vitro experiments identified macrophages as the dominant producers of these chemokines and revealed that \u03b2\n                    <jats:sub>2<\/jats:sub>\n                    \u2010adrenergic receptor signaling drives\n                    <jats:italic>Cxcl2<\/jats:italic>\n                    expression in response to stress\u2010related catecholamines. In parallel, neutrophils themselves were reprogrammed toward an immunosuppressive phenotype under stress. This phenotypic shift was already evident in bone marrow neutrophils, where activation of the hypothalamic\u2013pituitary\u2013adrenal (HPA) axis led to corticosterone\u2010driven, glucocorticoid receptor\u2013dependent induction of an immunosuppressive gene. These findings define a coordinated neuroendocrine mechanism in which psychological stress remodels myeloid cell function through sympathetic and HPA axis signaling, thereby fostering an immunosuppressive tumor microenvironment that promotes HCC progression. While pharmacologic blockade of either axis may mitigate stress\u2010driven tumor growth, our findings suggest that non\u2010pharmacological stress\u2010reduction strategies could represent a valuable complementary approach in managing HCC progression.\n
