Perfusability And Immunogenicity Of Implantable Pre-Vascularized Tissues Recapitulating Features Of Native Capillary Network, Dhavan Sharma, Archita Sharma, Linghao Hu, Te An Chen, Sarah Voon, Kayla J. Bayless, Jeremy Goldman, Alex J. Walsh, Feng Zhao

Michigan Tech Publications

Vascularization is a key pre-requisite to engineered anatomical scale three dimensional (3-D) constructs to ensure their nutrient and oxygen supply upon implantation. Presently, engineered pre-vascularized 3-D tissues are limited to only micro-scale hydrogels, which meet neither the anatomical scale needs nor the complexity of natural extracellular matrix (ECM) environments. Anatomical scale perfusable constructs are critically needed for translational applications. To overcome this challenge, we previously developed pre-vascularized ECM sheets with long and oriented dense microvascular networks. The present study further evaluated the patency, perfusability and innate immune response toward these pre-vascularized constructs. Macrophage-co-cultured pre-vascularized constructs were evaluated in vitro to …

+Protective Roles For Interferon-Gamma In Astrocytes During Chronic Autoimmunity, Brandon C. Smith

ETD Archive

Multiple sclerosis (MS) is an inflammatory and neurodegenerative disease of the central nervous system (CNS). Infiltrating inflammatory immune cells perpetuate demyelination and axonal damage in the CNS and significantly contribute to pathology and clinical deficits. Interferon (IFN)γ is classically described as deleterious in acute CNS autoimmunity, we and others have shown astrocytic IFNγ signaling also has a neuroprotective role. We found IFNγ signaling on astrocytes upregulates subunits of the immunoproteasome (iP) and programmed death ligand 1 (PD-L1), both of which serve protective roles during autoimmunity. Astrocyte-specific knockouts of Ifngr1 resulted in increased clinical severity in the MS murine model, experimental …

Exploration Of Secondary Structure Directing Agents On The Formation Of Hierarchical And 2d Zeolites, Suleiman Yahaya

ETD Archive

Hierarchical and 2D zeolites address the diffusion limitation of conventional zeolites by enhancing diffusion in the mesopores. So far, the surfactant compounds, which successfully produce hierarchical zeolites, have complex molecular structures making the zeolite synthesis expensive and uncompetitive for commercialization, making cost-effective synthesis of hierarchical and 2D zeolite highly desirable. However, the development of effective synthesis protocols relies on a good understanding of the SDA's influence on crystal morphology development, which is largely unknown. Here, we explore inexpensive and readily available compounds via a dual-SDA strategy and use MFI zeolite as the model system for the research. TPAOH served as …

Protective Responses Of The Intestinal Epithelial Cell Line Ht-29 Cells Exposed To Dephosphorylated Salmonella Flagellin [Research Note], Heyeon Baik, Jaiesoon Cho

The Philippine Agricultural Scientist

This study aimed to describe the effects of Salmonella Typhimurium flagellin (SFL) dephosphorylated by sweet potato purple acid phosphatase (PAP) on the protective responses of the intestinal epithelial cell line HT-29 cells. The enzyme was reported to display a broad substrate specificity for various organic phosphorylated conjugates and phosphoproteins. Dephosphorylation of SFL by sweet potato PAP decreased to 35% in the presence of 0.05 mM vanadate as compared with the negative control (p < 0.05). Intact SFL and the SFL treated with sweet potato PAP did not remarkably induce the activation of caspase-3 in HT-29 cells at all the tested levels of the substrate. Intact SFL maximally induced the release of IL (interleukin)-8 in HT-29 cells at 1000 ng/mL (p < 0.05). However, the SFL treated with the enzyme inhibited the release of IL-8 at over 100 ng/mL of the substrate as compared with intact SFL, resulting in an approximately 8-fold decrease even at 1000 ng/mL (p < 0.05). The SFL treated with the enzyme decreased the activation of the total ERK1/2 in the cells to 1.9 and 1.7–fold at 10 and 1000 ng/mL of the substrate, respectively, as compared with intact SFL (p < 0.05). In conclusion, sweet potato PAP could be a promising tool for controlling excessive inflammation during Salmonella infection in animal husbandry, and the enzyme could be a safe alternative that can overcome the drawbacks of chemotherapy.

Biology Faculty Works

The dissolution of anthropogenic carbon dioxide (CO2) in seawater has altered its carbonate chemistry in the process of ocean acidification (OA). OA affects the viability of marine species. In particular, calcifying organisms and their early planktonic larval stages are considered vulnerable. These organisms often utilize energy reserves for metabolism rather than growth and calcification as supported by bulk RNA-sequencing (RNA-seq) experiments. Yet, transcriptomic profiling of a bulk sample reflects the average gene expression of the population, neglecting the variations between individuals, which forms the basis for natural selection. Here, we used single-embryo RNA-seq on larval sea urchin Heliocidaris crassispina, which …
