Cancer treatments in veterinary medicine continue to evolve beyond the established standard therapies of surgery, chemotherapy and radiation therapy. New technologies in cancer therapy include a targeted mechanism to open the cell membrane based on electroporation, driving therapeutic agents, such as chemotherapy (electro-chemotherapy), for local control of cancer, or delivery of gene-based products (electro-gene therapy), directly into the cancer cell to achieve systemic control. This review examines electrochemotherapy and electro-gene therapy in veterinary medicine and considers future directions and applications.

The food safety risks posed by exposure to polystyrene microplastics (PS-MPs) and bisphenol A (BPA) have become an issue worldwide. However, the toxic effects of PS-MPs and BPA coexposure on the mammalian liver remain elusive. In this study, we found that PS-MPs and BPA coexposure have synergistic toxic effects on AML12 cells and the mouse liver.

Interleukin 33 (IL-33) is a pleiotropic cytokine released from diverse cell types that regulate both pro- and anti-inflammatory responses during pathogen infection. However, it remains unclear whether IL-33 controls key aspects of cutaneous immunity against skin-penetrating parasites. In this study, mice percutaneously infected with the parasitic helminth Strongyloides ratti were investigated to understand mechanisms of anamnestic immunity at the skin barrier.

The humoral immune system influences the development of atherosclerosis, but the contributions of specific memory B cell subsets and IgG isotypes are poorly understood. We assessed the relationship between atherosclerosis and age-associated B cells (ABCs), a T-bet-expressing memory B cell subset that is enriched for IgG2c production and implicated in humoral autoimmunity. We found increased numbers of splenic CD11c+ ABCs in 6-mo-old, chow-fed Apoe-/- mice versus C57BL/6 control mice, which were exacerbated by high-fat diet.

6-methyladnosine (mA) modification is present in both positive- and negative-strand RNA of influenza A virus (IAV) and affects the replication and pathogenicity of IAV. However, little is known about the regulatory mechanism of mA in IAV RNA. In the present study, we identified the mA methylation of the viral RNA of different IAV subtypes and confirmed that mA modification promotes the polymerase activity and replication of IAV.

Chronic infections with hepatitis E virus (HEV), especially those of genotype 3 (G3), frequently lead to liver fibrosis and cirrhosis in patients. However, the causation and mechanism of liver fibrosis triggered by chronic HEV infection remain poorly understood. Here, we found that the viral multiple-domain replicase (ORF1) undergoes unique ubiquitin-proteasomal processing leading to formation of the EV-erived MAD ctivator (HDSA), a viral polypeptide lacking putative helicase and RNA polymerase domains.
