Dendritic cells (DCs) are professional antigen-presenting cells that act as a bridge between innate immunity and adaptive immunity. After activation, DCs differentiate into subtypes with different functions, at which point they upregulate co-stimulatory molecules and produce various cytokines and chemokines. Activated DCs also process antigens for presentation to T cells and regulate the differentiation and function of T cells to modulate the immune state of the body. Non-coding RNAs, RNA transcripts that are unable to encode proteins, not only participate in the pathological mechanisms of autoimmune-related diseases but also regulate the function of immune cells in these diseases. Accumulating evidence suggests that dysregulation of non-coding RNAs contributes to DC differentiation, functions, and so on, consequently producing effects in various autoimmune diseases. In this review, we summarize the main non-coding RNAs (miRNAs, lncRNAs, circRNAs) that regulate DCs in pathological mechanisms and have tremendous potential to give rise to novel therapeutic targets and strategies for multiple autoimmune diseases and immune tolerance-related diseases.
Abstract Gastric cancer (GC) ranks among the leading causes of cancer‐related mortality globally. Often, its initial stages manifest subtly, and the infrequency of routine screenings contributes to late diagnoses in many cases. Systemic treatments for GC include chemotherapy, targeted therapy, and immunotherapy, among which immunotherapy is the first‐line standard treatment for advanced GC. In recent years, immunotherapy has seen notable advancements, as evidenced by the Food and Drug Administration's approval of drugs such as nivolumab and pembrolizumab for GC treatment. Additionally, several other drugs are currently under rigorous preclinical and clinical investigation. This review aims to shed light on the recent advancements in immunotherapy for GC, particularly emphasizing the insights gained from phase 2/3 clinical trials that assess the efficacy, safety, and promise of various immunotherapeutic modalities, including immune checkpoint inhibitors, CAR‐T‐cell therapies, and cancer vaccines, in enhancing patient outcomes. Moreover, this review delves into the intricate immunological framework of GC, focusing on the tumor microenvironment, interactions among immune cells, and the roles of immune checkpoints such as PD‐L1. We also address the hurdles and prospective paths forward in the realm of immunotherapy for GC, offering fresh viewpoints on potential therapeutic approaches in this evolving domain.

Hepatocellular carcinoma is the fifth most common cancer and durable responses in conventional treatments are limited so researchers have been devoted to developing new anti-HCC agents.
Fibrosis is an excessive wound-healing response induced by repeated or chronic external stimuli to tissues, significantly impacting quality of life and primarily contributing to organ failure. Organ fibrosis is reported to cause 45% of all-cause mortality worldwide. Despite extensive efforts to develop new antifibrotic drugs, drug discovery has not kept pace with the clinical demand. Currently, only pirfenidone and nintedanib are approved by the FDA to treat pulmonary fibrotic illness, whereas there are currently no available antifibrotic drugs for hepatic, cardiac or renal fibrosis. The development of fibrosis is closely related to epigenetic alterations. The field of epigenetics primarily studies biological processes, including chromatin modifications, epigenetic readers, DNA transcription and RNA translation. The bromodomain and extra-terminal structural domain (BET) family, a class of epigenetic readers, specifically recognizes acetylated histone lysine residues and promotes the formation of transcriptional complexes. Bromodomain-containing protein 4 (BRD4) is one of the most well-researched proteins in the BET family. BRD4 is implicated in the expression of genes related to inflammation and pro-fibrosis during fibrosis. Inhibition of BRD4 has shown promising anti-fibrotic effects in preclinical studies; however, no BRD4 inhibitor has been approved for clinical use. This review introduces the structure and function of BET proteins, the research progress on BRD4 in organ fibrosis, and the inhibitors of BRD4 utilized in fibrosis. We emphasize the feasibility of targeting BRD4 as an anti-fibrotic strategy and discuss the therapeutic potential and challenges associated with BRD4 inhibitors in treating fibrotic diseases.
