Cholinergic Inhibition Of Lipopolysaccharide Induced Matrix Metalloproteinase In Immune Cells., Harrison Black,

Electronic Theses and Dissertations

Background: Matrix metalloproteinase (MMPs) are proteins that have a unique role in immunity, tissue remodeling, and tumorigenesis. MMPs can break down extracellular components, release bioactive molecules, and act on pro-inflammatory cytokines, chemokines and other proteins to regulate varied aspects of inflammation and immunity. Nicotine (3-(1-methyl-2-pyrrolidinyl) pyridine), a key toxic component of tobacco, is thought to dysregulate matrix metalloproteinase secretion in immune cells. Aim: Examine the effect of nicotine on MMP9 secretion and activity in primary monocytes. Methods: Primary monocytes were stimulated with LPS (1 µg/ml) and Nicotine (100 ng/ml) and MMP9 secretion were studied. Gel zymography and ELISA techniques were …

Interleukin-6 Production And Epithelial Cell Signaling By Telomerase Immortalized Gingival Keratinocytes In Porphyromonas Gingivalis Infection., Himabindu Vuddaraju

Electronic Theses and Dissertations

P. gingivalis is a major periodontal disease causing pathogen. Gingival epithelial cells being the first line of defense, interact and internalize the bacteria evoking a cell signaling response that finally leads to the release of cytokines. IL-6 is a potent pro- inflammatory cytokine, which is one of the responsible factors for bone resorption, a clinical manifestation of periodontitis. The experimental model study hypothesizes that P. gingivalis infection increases the production of IL-6 in telomerase immortalized gingival keratinocytes (TIGKs) through up-regulation of c-Jun (AP-1 reporter). We observed the IL-6 production post-infection with P. gingivalis WT ATCC33277 and mutants ?0482, ?Ndk and …

Neurotrophic Factor Gdnf Promotes Survival Of Salivary Stem Cells, Nan (Tori) Xiao, Yuan Lin, Hongbin Cao, Davud Sirjani, Amato J. Giaccia, Albert C. Koong, Christina S. Kong, Maximilian Diehn, Quynh-Thu Le

All Dugoni School of Dentistry Faculty Articles

Stem cell-based regenerative therapy is a promising treatment for head and neck cancer patients that suffer from chronic dry mouth (xerostomia) due to salivary gland injury from radiation therapy. Current xerostomia therapies only provide temporary symptom relief, while permanent restoration of salivary function is not currently feasible. Here, we identified and characterized a stem cell population from adult murine submandibular glands. Of the different cells isolated from the submandibular gland, this specific population, Lin-CD24+c-Kit+Sca1+, possessed the highest capacity for proliferation, self renewal, and differentiation during serial passage in vitro. Serial transplantations of this stem cell population into the submandibular gland …

Tooth Loss Strongly Associates With Malnutrition In Chronic Kidney Disease, Efthimia Effie Ioannidou, Helen Swede

UCHC Articles - Research

Background

In chronic kidney disease (CKD), inadequate nutritional intake, inflammation, and increased oxidative stress have been the major contributing factors in malnutrition pathogenesis. However, there is still a paucity of evidence assessing the magnitude of the effect of tooth loss on malnutrition in CKD populations. The authors hypothesize that among patients with CKD, tooth loss may affect nutritional status, using the National Health and Nutrition Examination Survey 1988 to 1994 (NHANES III).

Methods

Glomerular filtration rate (GFR) was estimated based on cystatin C levels using the relevant equation. Urinary albumin-to-creatinine ratio (albuminuria) was calculated in milligrams per gram with a …
