A catalytic self-assembled DNA dendritic complex was herein reported and used for siRNA-based gene silencing. This kind of one-pot DNA dendrimer can be conveniently prepared as needed, and it was demonstrated to have better silencing efficiency and lower cytotoxicity than commercial cationic lipid transfection agents.

In situ vaccine (ISV) can activate the anti-tumor immune system by inducing immunogenic cell death (ICD) at the tumor site. However, the development of tumor ISV still faces challenges due to insufficient tumor antigens released by tumor cells and the existence of tumor immunosuppressive microenvironment (TIME). Targeting the STING pathway has been reported to enhance the adjuvant effects of in situ tumor vaccines by initiating innate immunity.

In this editorial, we comment on the article by Mu , published in the recent issue of the . We pay special attention to the immune tolerance mechanism caused by hepatitis B virus (HBV) infection, the pathogenesis of hepatocellular carcinoma (HCC), and the role of antiviral therapy in treating HCC related to HBV infection. HBV infection leads to systemic innate immune tolerance by directly inhibiting pattern recognition receptor recognition and antiviral signaling pathways, as well as by inhibiting the immune functions of macrophages, natural killer cells and dendritic cells.

Dendritic cells are the most potent antigen-presenting cells in immune therapeutic approaches for chronic hepatitis B (CHB) infection. Here, we developed a clinical trial to evaluate the efficacy and safety of autologous HBV vaccine-pulsed DCs and their induced T cells (HPDCT) in CHB patients. This was a randomised, prospective, open-label, multicentre, superiority study and 309 treatment-naive CHB patients were divided into HPDCT plus nucleos(t)ide analogues (NAs) group (n = 84), NAs mono-therapy group (n = 82), HPDCT plus Peg-interferon (Peg-IFN) group (n = 69), Peg-IFN mono-therapy group (n = 74).

Background: Regulation of messenger RNA (mRNA) transport and translation in neurons is essential for dendritic plasticity and learning/memory development. The trafficking of mRNAs along the hippocampal neuron dendrites remains translationally silent until they are selectively transported into the spines upon glutamate-induced receptor activation. However, the molecular mechanism(s) behind the spine entry of dendritic mRNAs under metabotropic glutamate receptor (mGluR)-mediated neuroactivation and long-term depression (LTD) as well as the fate of these mRNAs inside the spines are still elusive.

Cell division cycle-associated (CDCA) genes are dysregulated in carcinomas. Our study aims to identify similarities and differences of the clinical roles of CDCAs in breast cancer (BRCA) and to explore their potential mechanisms. In GEPIA, compared to normal tissues, expressions of CDCAs were higher in BRCA and sub-types.
