Abstract Background The efficacy of immune checkpoint blockade therapy in patients with hepatocellular carcinoma (HCC) remains poor. Although serine‐ and arginine‐rich splicing factor (SRSF) family members play crucial roles tumors, their impact on tumor immunology unclear. This study aimed to elucidate the role SRSF10 HCC immunotherapy. Methods To identify key genes associated immunotherapy resistance, we conducted single‐nuclear RNA sequencing, multiplex immunofluorescence, Cancer Genome Atlas Gene Expression Omnibus database analyses. We investigated biological functions evasion using vitro co‐culture systems, flow cytometry, various tumor‐bearing mouse models, patient‐derived organotypic spheroids. Results was upregulated tumors poor prognosis. Moreover, positively regulated lactate production, SRSF10/glycolysis/ histone H3 lysine 18 lactylation (H3K18la) formed a positive feedback loop cells. Increased levels promoted M2 macrophage polarization, thereby inhibiting CD8 + T cell activity. Mechanistically, interacted 3′‐untranslated region MYB , enhancing stability, subsequently upregulating glycolysis‐related enzymes including glucose transporter 1 ( GLUT1 ), hexokinase HK1 dehydrogenase A LDHA resulting elevated intracellular extracellular levels. Lactate accumulation induced lactylation, which further expression. Additionally, produced by H3K18la site upon transport into macrophages, activating transcription pro‐tumor turn, inhibited enrichment cells proportion interferon‐γ microenvironment (TME), thus creating an immunosuppressive TME. Clinically, could serve as biomarker for assessing resistance solid tumors. Pharmacological targeting selective inhibitor 1C8 enhanced programmed death (PD‐1) monoclonal antibodies (mAbs) both murine human preclinical models. Conclusions SRSF10/MYB/glycolysis/lactate axis is critical triggering anti‐PD‐1 resistance. Inhibiting may overcome tolerance HCC.

Lactylation, a post-translational modification, has been linked to gene transcription regulation through epigenetic modulation in various pathophysiological processes. The lactylation regulatory proteins, known as writers, erasers, and readers, govern their dynamics by adding, removing, recognizing lactyl groups on proteins. Macrophages, cells of the immune system, maintain homeostasis, responding dynamically diverse internal external stimuli. Emerging researches unveil that lactylation, inducing macrophage activation polarization, affects functionality pathological conditions such inflammation, tumor microenvironment, fibrosis. Evidence progressively indicates lactate-driven alterations levels within macrophages can influence pathogenesis numerous diseases. This review aims systematically summarize research progress macrophages, explore its functions mechanisms which contributes pathology different disease phenotypes, propose future directions along with potential diagnostic therapeutic strategies.

Abstract Macrophages are immune cells belonging to the mononuclear phagocyte system. They play crucial roles in defense, surveillance, and homeostasis. This review systematically discusses types of hematopoietic progenitors that give rise macrophages, including primitive progenitors, erythro-myeloid stem cells. These have distinct genetic backgrounds developmental processes. Accordingly, macrophages exhibit complex diverse functions body, phagocytosis clearance cellular debris, antigen presentation, response, regulation inflammation cytokine production, tissue remodeling repair, multi-level regulatory signaling pathways/crosstalk involved homeostasis physiology. Besides, tumor-associated a key component TME, exhibiting both anti-tumor pro-tumor properties. Furthermore, functional status is closely linked development various diseases, cancer, autoimmune disorders, cardiovascular disease, neurodegenerative metabolic conditions, trauma. Targeting has emerged as promising therapeutic strategy these contexts. Clinical trials macrophage-based targeted drugs, immunotherapies, nanoparticle-based therapy were comprehensively summarized. Potential challenges future directions targeting also been discussed. Overall, our highlights significance this versatile cell human health which expected inform research clinical practice.
