Nanoparticles (NPs) are effective and safe adjuvants for antigen delivery in modern vaccinology. Biodegradable nanomaterials with suitable properties are frequently applied for conjugation or loading with antigens; they protect the antigens from degradation in vivo. NPs are applied as effective delivery system to facilitate antigen uptake by antigen presenting cells (APCs) and especially dendri...

Liver fibrosis occurs as a wound-healing scar response following acute and chronic liver inflammation including alcoholic liver disease, non-alcoholic steatohepatitis, hepatitis B and C, and autoimmune hepatitis. Myofibroblasts, mainly transdifferentiated from hepatic stellate cells, are pivotal cell types that produce fibrillar collagen. The activation of inflammatory cells, including Kupffer ...

The hepatitis B virus (HBV) infects hepatocytes, which are the main cell type composing a human liver. However, the liver is enriched with immune cells, particularly innate cells (e.g., myeloid cells, natural killer and natural killer T-cells (NK/NKT), dendritic cells (DCs)), in resting condition. Hence, the study of the interaction between HBV and innate immune cells is instrumental to: (1) be...

background and aims: this study examined sub-chronic effects of methamphetamine (meth) on the stereological parameters in the cornu ammonis (ca) of the hippocampus in adult mice. materials and methods: fifteen adult male mice, eight weeks old, were randomly divided into three groups: receive saline (controls), or low-dose (ld) 2.5 mg/kg meth, or high-dose (hd) 25 mg/kg meth, via daily intraperi...
