MicroRNAs (miRNAs) are single-stranded noncoding RNAs with 18 to 25 nucleotides and play critical roles in a wide spectrum of biological processes. We repored that miR-185 inhibited hepatitis B surface antigen (HBsAg) expression and hepatitis B virus (HBV) replication without affecting the proliferation of HepG2 2.2.15 cells, compared with the controls. We identified that protein kinase C eta (PRKCH) is a direct target gene of miR-185 that affects HBV replication and protein expression and that the miR-185 may suppress HBV replication. Our results provide more information for gene therapy in HBV infection. Keywords: miR-185; HBV; HBV surface antigen; viral replication; PRKCH.
Macrophages are versatile myeloid leukocytes with flexible cellular states to perform diverse tissue functions beyond immunity. This plasticity is however often hijacked by diseases to promote pathology. Scanning kinetics of macrophage states by single-cell transcriptomics and flow cytometry, we observed atopic dermatitis drastically exhausted a resident subtype S1.
Objectives: This study aimed to evaluate the efficacy of low-dose interleukin (IL-2) treatment for bullous pemphigoid (BP) caused by anti-programmed cell death protein 1/ligand 1 (PD-1/PD-L1) inhibitors.
Methods: Low-dose IL-2 treatment was standardized for BP. The Bullous Pemphigoid Disease Area Index (BPDAI), 5D-Itch Scale (5D-IS), and Dermatology Life Quality Index (DLQI) were recorded before and after treatment, and hexachromatic lymphocytes, regulatory T cells (Treg cells), and cytokines were measured.
Background: Mutations commonly occur in cancer cells, arising neoantigen as potential targets for personalized immunotherapy of lung adenocarcinoma (LUAD). However, the substantial heterogeneity observed among individuals and distinct foci within the same patient presents significant challenges in formulating immunotherapy strategies. The aim of the work is to characterize the mutation pattern and identify neopeptides across different patients and diverse foci within the same patients with LUAD.

Background: Programmed death-ligand 1 (PD-L1) expression is abundant not only in malignant cells but also in infiltrating cells within the tumor microenvironment (TME) of hepatocellular carcinoma (HCC). This study explored the association between PD-L1 expression in TME and outcomes in HCC patients treated with atezolizumab plus bevacizumab (AB), emphasizing the implications of PD-L1 expression in both malignant and tumor-infiltrating cells.
Methods: This study included 72 patients with HCC who underwent percutaneous core needle liver biopsy before AB treatment between September 2020 and December 2023.
Objectives: To evaluate the manufacturability, efficacy and safety of allogeneic CD19 chimeric antigen receptor double-negative T cells (CD19-CAR-DNTs) as an off-the-shelf therapeutic cell product.
Methods: A membrane proteome array was used to assess the off-target binding of CD19-CAR. DNTs derived from healthy donors were transduced with lentiviral vectors encoding the CD19-CAR.
