'Mast cells, important sensor and effector cells of the immune system, may influence bone metabolism as their number is increased in osteoporotic patients. They are also present during bone fracture healing with currently unknown functions. Using a novel c-Kit-independent mouse model of mast cell deficiency, we demonstrated that mast cells ... More
Small Heterodimer Partner Deficiency Increases Inflammatory Liver Injury Through C-X-C motif chemokine ligand 2-Driven Neutrophil Recruitment in Mice.

'Although detailed pathophysiological mechanisms of fulminant hepatitis remain elusive, immune cell recruitment with excessive cytokine production is a well-recognized hallmark of the disease. We determined the function of orphan nuclear receptor small heterodimer partner (SHP) in concanavalin A (ConA)-induced hepatitis model. Male C57BL/6 J mice were injected intravenously with either ...

'The Enteric Nervous System (ENS) is a complex network of neurons and glia, which regulates sensorimotor function throughout the gastroinestinal tract (GI). Here we investigated the role of the ENS and intestinal myofibroblasts in the maintenance of a primary intestinal epithelial barrier through regulation of monolayer permeability, cytokine production, and ...

'Bacterial colonization of epithelial surfaces and subsequent transmigration across the mucosal barrier are essential for the development of infection. We hypothesized that the methyl-accepting proteins (MCPs), known as chemoreceptors expressed on Escherichia coli (E. coli) bacterial surface, play an important role in mediating bacterial transmigration. We demonstrated a direct interaction ... More
3D Organotypic Spinal Cultures: Exploring Neuron and Neuroglia Responses Upon Prolonged Exposure to Graphene Oxide.

Graphene-based nanomaterials are increasingly engineered as components of biosensors, interfaces or drug delivery platforms in neuro-repair strategies. In these developments, the mostly used derivative of graphene is graphene oxide (GO). To tailor the safe development of GO nanosheets, we need to model ... More
