Golgi membrane protein 1 (GOLM1) has been found to be positively correlated with infiltrating TAMs expressing high levels of PD‐L1 and CD8 T cell suppression in HCC tissues.[48] GOLM1 can regulate the exocytosis activities by promoting the cargo transportation of exosomes, which will promote the delivery of PD‐L1 to the macrophages equipped with the exosome carrier. Here, GOLM1 is linked to hepatocellular carcinoma.
