The ALTER-L038 study aimed to evaluate efficacy and safety of a chemotherapy-free combination of benmelstobart, an anti-programmed cell death ligand 1 antibody, and anlotinib, a small-molecule multi-target anti-angiogenic TKI, in EGFR-positive advanced NSCLC patients who progressed after EGFR TKI therapy. Patients were enrolled in a phase I/II study. In phase I (dose-escalation), patients received anlotinib (8, 10, 12 mg) plus benmelstobart (1200 mg). Recommended phase II dose, determined during phase I, was used in phase II dose-expansion cohort. Primary endpoints were maximum tolerable dose in phase I and progression-free survival (PFS) in phase II. At the data cutoff date (March 10, 2024), 55 patients were enrolled in phase II dose-expansion cohort. Median PFS of patients included in phase II cohort was 9.0 months, median overall survival was 28.9 months, objective response rate was 25.5%, disease control rate was 87.3%, and median duration of response was 19.8 months. Incidence of grade ≥3 treatment-related adverse events in study population was 25.5% (14/55), whereas grade ≥3 immune-related adverse events occurred in 10.9% (6/55) of patients. Benmelstobart plus anlotinib showed promising anti-tumor efficacy with tolerable safety profile, supporting the value of further development of this convenient chemotherapy-free regimen for patients with EGFR-positive advanced NSCLC who progressed after EGFR TKI therapy.

Conversely, their pivotal role in immune regulation implicates them in the pathophysiology of various diseases, such as infectious diseases, autoimmune disorders, metabolic diseases, and cancers. In this context, IRFs display a dichotomous nature, functioning as both tumor suppressors and promoters, contingent upon the specific disease milieu. Post-translational modifications of IRFs, including phosphorylation and ubiquitination, play a crucial role in modulating their function, stability, and activation.

However, its impact on the antiviral innate immune response remains largely unknown. Here, we identify that AXIN1 acts as an effective regulator of antiviral innate immunity against both DNA and RNA virus infections. In the resting state, AXIN1 maintains the stability of the transcription factor interferon regulatory factor 3 (IRF3) by preventing p62-mediated autophagic degradation of IRF3. This is achieved by recruiting ubiquitin-specific peptidase 35 (USP35), which removes lysine (K) 48-linked ubiquitination at IRF3 K366. Upon virus infection, AXIN1 undergoes a phase separation triggered by phosphorylated TANK-binding kinase 1 (TBK1). This leads to increased phosphorylation of IRF3 and a boost in IFN-I production. Moreover, KYA1797K, a small molecule that binds to the AXIN1 RGS domain, enhances the AXIN1-IRF3 interaction and promotes the elimination of various highly pathogenic viruses. Clinically, patients with HBV-associated hepatocellular carcinoma (HCC) who show reduced AXIN1 expression in pericarcinoma tissues have low overall and disease-free survival rates, as well as higher HBV levels in their blood.

The metabolic regulation of the immune system is important in the pathogenesis and progression of numerous diseases, such as cancers, autoimmune diseases and metabolic diseases. The concept of immunometabolism was introduced over a decade ago to elucidate the intricate interplay between metabolism and immunity. The definition of immunometabolism has expanded from chronic low-grade inflammation in metabolic diseases to metabolic reprogramming of immune cells in various diseases. With immunometabolism being proposed and developed, the metabolic regulation of the immune system can be gradually summarized and becomes more and more clearer. In the context of many diseases including cancer, autoimmune diseases, metabolic diseases, and many other disease, metabolic reprogramming occurs in immune cells inducing proinflammatory or anti-inflammatory effects. The phenotypic and functional changes of immune cells caused by metabolic regulation further affect and development of diseases. Based on experimental results, targeting cellular metabolism of immune cells becomes a promising therapy. In this review, we focus on immune cells to introduce their metabolic pathways and metabolic reprogramming, and summarize how these metabolic pathways affect immune effects in the context of diseases. We thoroughly explore targets and treatments based on immunometabolism in existing studies. The challenges of translating experimental results into clinical applications in the field of immunometabolism are also summarized.

Small molecule metabolites such as ADP-heptose are synthesized by HBEs exhibiting isomerase, kinase, phosphatase, and nucleotidyltransferase activities. Of note, three subgroups of HBEs with nucleotidyltransferase activity (HENases) exist, exhibiting solely this activity or combined with kinase, or isomerase/kinase activities. In bacteria, where HBEs were first reported, they catalyzed the four-step biosynthesis of ADP-heptose starting from D-sedoheptulose 7-phosphate. Functional HBEs are prevalent in bacteria, archaea, viruses, and some eukaryotes. The authors discovered the presence of a widely conserved arginine residue at the fifth N-terminal position of the (F/L)XXGXSTT motif (STT_R5) in HENases that enable them to synthesize also CDP- and UDP-heptoses. A striking feature of the NDP-heptoses is their ability to act as immunostimulants. Pathogenic organisms deliver NDP-heptoses into mammalian cells, where they are detected by ALPK1, triggering its kinase activity. The ensuing TIFA phosphorylation initiates a signaling cascade to activate NF-κB, leading to the release of cytokines and chemokines that result in the recruitment of immune cells. In addition, NDP-heptoses could also serve as building blocks for protein glycosylation, or the production of LPS or antibiotics.
