The baculovirus Autographa californica multiple nuclear polyhedrosis virus (AcMNPV) has been widely used in biotechnology for protein expression in insect cells. Baculoviruses use arthropods as their natural hosts and are unable to replicate in mammalian cells. However, AcMNPV is able to enter many mammalian cell types and can be used for transgene expression if engineered to contain suitable expression cassettes. In this chapter, we describe the construction and application of a recombinant baculovirus containing a bicistronic expression cassette that can be used for stable protein expression in mammalian cells. As an example, the generation of glioblastoma and hepatocellular carcinoma cell lines stably expressing green fluorescent protein after puromycin selection is shown.

Idiopathic multicentric Castleman disease (iMCD) is a rare lymphoproliferative disorder characterized by systemic inflammation and lymphadenopathy. Two major clinical subtypes, idiopathic plasmacytic lymphadenopathy (iMCD-IPL) and iMCD with thrombocytopenia, anasarca, fever, renal dysfunction/reticulin fibrosis, and organomegaly (iMCD-TAFRO), exhibit distinct pathophysiologic mechanisms. While interleukin-6 (IL-6) is known to be elevated in iMCD, the differences in IL-6 production sources between subtypes remain unclear.

Background: Despite promising preclinical results, remote limb ischemic postconditioning efficacy in human stroke treatment remains unclear, with mixed clinical trial outcomes. A potential reason for translational difficulties could be differences in circadian rhythms between nocturnal rodent models and diurnal humans.
Methods: Male C57BL/6J mice were subjected to transient focal cerebral ischemia and then exposed to remote postconditioning during their active or inactive phase and euthanized at 24 hours and 3 days.

Background: Atherosclerosis is a chronic inflammatory disease characterized by the accumulation of lipid-laden foam cells and plaques within the arterial wall. Dysfunctional vascular smooth muscle cells (VSMCs), fibroblasts, endothelial cells, and macrophages contribute to disease progression. Here, we report that macrophage-specific expression of epsins, highly conserved endocytic adaptor proteins involved in clathrin-mediated endocytosis, accelerates atherosclerosis in Western diet-fed mice.

Migraine is a complex neurological disorder involving multiple neuropeptides that modulate nociceptive and sensory pathways. The most studied peptide is calcitonin gene-related peptide (CGRP), which is a well-established migraine trigger and therapeutic target. Recently, another peptide, pituitary adenylate cyclase-activating polypeptide (PACAP), has emerged as an alternative target for migraine therapeutics.

Major depressive disorder is a prevalent and debilitating psychiatric illness that produces significant disability. Clinical data suggest that the pathophysiology of depression is due, in part, to a dysregulation of inflammation and glutamate levels in the brain. The systemic administration of lipopolysaccharide (LPS) has been shown to induce depressive-like behaviors in mice.
