While transcatheter arterial embolization (TAE) is the accepted locoregional therapy, embolization inevitably induces severe intratumoral hypoxia, leading to excessive lactate accumulation, metabolic reprogramming and the formation of an immunosuppressive tumor microenvironment (TME), factors that collectively limit durable therapeutic efficacy and promote tumor recurrence. Although immunotherapy has shown promise in HCC, the efficacy of combining TAE with immune-based strategies remains suboptimal, largely due to metabolic constraints and T cell dysfunction within the post-embolization TME. Interleukin-2 (IL-2) therapy can stimulate effector T cells but suffers from the drawbacks of systemic toxicity, a short half-life and TME-induced dysfunction. Recent evidence indicates that lactate-rich, acidic TMEs impair IL-2 stability and signaling, suppress CD8⁺ T cell function, and promote Treg cell activity, thereby further compromising IL-2-based immunotherapy following TAE. Here, we developed a nano-immunotherapy platform (Syr/IL-2@MPDA) using mesoporous polydopamine (MPDA) nanoparticles co-loaded with His-tagged IL-2 and the monocarboxylate transporter inhibitor Syrosingopine (Syr). Syr-mediated lactate regulation alleviates TME acidity and restores IL-2 activity, while MPDA enables mild photothermal therapy (mPTT) to transform immunologically “cold” tumors into “hot” phenotypes, thereby enhancing the immune response. This integrated strategy significantly enhanced antitumor immunity, achieving a tumor growth inhibition rate of 70.87% in a murine subcutaneous tumor model. In an orthotopic N1S1 HCC rat model, the treatment demonstrated strong therapeutic efficacy in combination with αPD-L1 and TAE, overcoming the hazards of TAE-induced lactate accumulation and immune suppression.

Non-selective targeting of collagen I through CAF inhibition may inadvertently promote tumor cell detachment and metastasis by triggering anoikis resistance. To address this, a “wandering tumor cells” strategy is proposed, combining the induction of tumor cell deadhesion with the reversal of anoikis resistance. For heterologous targeted drug delivery, thermosensitive lipids and a photosensitizer are incorporated into M1-type macrophage membranes (TMs) to enable laser-responsive activation. Based on this approach, we designed a photothermally triggered, functional macrophage membrane-camouflaged nano-cracker (TM@cP/siF-ErN) with a particle size of 162.20 ± 0.54 nm for the co-delivery of erianin (Er) and focal adhesion kinase small interfering RNA (siFAK). Er is encapsulated in anisamide (AA)-modified nanodiscs (ErN) with hydrodynamic diameter of 15.07 ± 7.24 nm to selectively inhibit collagen I synthesis in CAFs by targeting pyruvate carboxylase, thereby inducing tumor cell deadhesion. siFAK is delivered to tumor cells using cinnamaldehyde-modified polyethyleneimine (cP/siF) to formed complexes with a particle size of 98.57 ± 1.47 nm and enhance transfection efficiency, enabling effective FAK knockdown and reversal of tumor anoikis resistance. Furthermore, TMs are fragmented into debris to amplify M2-type macrophage repolarization. Experimental results show that the nano-cracker efficiently targets orthotopic 4T1 breast tumors and, upon laser-triggered detonation, releases ErN, cP/siF and M1-type macrophage membrane fragments, which collectively promote tumor anoikis by suppressing collagen I synthesis in CAFs and reversing tumor cell anoikis resistance. Moreover, it promotes the repolarization of M2-type macrophages, which synergizes with collagen I downregulation-induced infiltration of CD8⁺ T lymphocytes to enhance the antitumor immune response, collectively resulting in pronounced breast cancer suppression.

This review provides a comprehensive analysis of the molecular mechanisms underlying ERS and discusses how engineered nanotherapeutics can selectively target the endoplasmic reticulum through approaches such as ligand conjugation, peptide modification or membrane fusion to induce sustained ERS. These nanotherapeutics initiate ERS by mechanisms including calcium ion dysregulation, overproduction of reactive oxygen species and direct activation of unfolded protein response signaling pathways. Persistent ERS subsequently facilitates immunogenic cell death by promoting the release of damage-associated molecular patterns, which enhance the maturation of dendritic cell and promote the activation of cytotoxic T lymphocytes. Moreover, combining ER-targeted nanotherapeutics with established therapeutic modalities, such as photodynamic therapy, photothermal therapy and chemodynamic therapy, has demonstrated synergistic antitumor efficacy and improved immune responses. Despite these advances, several critical challenges remain, particularly in terms of delivery efficiency, targeting specificity and systemic biocompatibility. Future research should emphasize the integration of nanotechnology with systems immunology and cancer metabolism, as well as the incorporation of artificial intelligence and single-cell omics to optimize the design and translational potential of ER-targeted nanotherapeutics.
