“…In addition, it further revealed that the crosstalk between SPP1 + macrophages and CAFs contributed to ECM remodeling and TIB formation, which led to reducing immune infiltration in the tumor tissue. Moreover, in vivo experiments have verified that SPP1 inhibition in mice with liver cancer resulted in better immunotherapy efficacy with anti-PD-1 (111). Although the molecular mechanism of SPP1-mediated crosstalk between SPP1 + macrophages and CAFs is not completely clear and the role of the crosstalk between SPP1 + macrophages and CAFs has not been verified in clinical trials, SPP1-blockading is promising for improving the efficacy of HCC treatment with ICIs.…”

“…A lot of previous researches centered on linking various cells in TME with immunotherapy effectiveness. The latest study indicated that TME subtypes of HCC are associated to the immunotherapy efficacy by combining spatial transcriptomics with single-cell RNA sequencing (scRNA-seq) and multiplexed immunofluorescence of anti-PD-1-treated HCC patients ( 111 ). It suggested that the tumor immune barrier (TIB) structure consisting of SPP1 + macrophages and CAFs near the tumor boundary affected the therapeutic efficacy of ICIs.…”

“…Single-cell analysis in breast cancer has also shown that SPP1-positive TAMs express high levels of apolipoprotein E (APOE), CD204, CD68, and CADM1. High densities of SPP1-expressing TAMs and CAF appear associated with resistance to immunotherapy in hepatocellular carcinoma, and animal studies have revealed that SPP1 secreted from TAMs is involved in the infiltration of CAFs and suppression of CTL infiltration into tumor tissues [ 92 ]. Cancer stem cells of gastric cancer expressed high levels of CD44 [ 93 ].…”

“…Numerous studies have investigated the application of T cells in anti-tumor immunotherapies [8][9][10]. Nonetheless, the immunosuppressive tumor microenvironment (TME) in solid tumors, such as OSCC, continues to be a therapeutic barrier for current immunotherapy strategies [11,12]. In general, tumorassociated macrophages (TAMs), the most prevalent immune cells in ltrating in TEM, are a substantial component of the immune microenvironment and play an indispensable role in the body's innate immunity and acquired immunity [13,14].…”
