The Impact Of The Th17:Treg Axis On The Iga-Biome Across The Glycemic Spectrum, Heather T Essigmann, Kristi L Hoffman, Joseph F Petrosino, Goo Jun, David Aguilar, Craig L Hanis, Herbert L Dupont, Eric L Brown

Journal Articles

Secretory IgA (SIgA) is released into mucosal surfaces where its function extends beyond that of host defense to include the shaping of resident microbial communities by mediating exclusion/inclusion of respective microbes and regulating bacterial gene expression. In this capacity, SIgA acts as the fulcrum on which host immunity and the health of the microbiota are balanced. We recently completed an analysis of the gut and salivary IgA-Biomes (16S rDNA sequencing of SIgA-coated/uncoated bacteria) in Mexican-American adults that identified IgA-Biome differences across the glycemic spectrum. As Th17:Treg ratio imbalances are associated with gut microbiome dysbiosis and chronic inflammatory conditions such as …

Impact Of Diabetes On The Gut And Salivary Iga Microbiomes, Eric L Brown, Heather T Essigmann, Kristi L Hoffman, Noah W Palm, Sarah M Gunter, Joel M Sederstrom, Joseph F Petrosino, Goo Jun, David Aguilar, William B Perkison, Craig L Hanis, Herbert L Dupont

Journal Articles

Mucosal surfaces like those present in the lung, gut, and mouth interface with distinct external environments. These mucosal gateways are not only portals of entry for potential pathogens but also homes to microbial communities that impact host health. Secretory immunoglobulin A (SIgA) is the single most abundant acquired immune component secreted onto mucosal surfaces and, via the process of immune exclusion, shapes the architecture of these microbiomes. Not all microorganisms at mucosal surfaces are targeted by SIgA; therefore, a better understanding of the SIgA-coated fraction may identify the microbial constituents that stimulate host immune responses in the context of health …

Examining Measurement Reactivity In Daily Diary Data On Substance Use: Results From A Randomized Experiment., Anne Buu, Songshan Yang, Runze Li, Marc A Zimmerman, Rebecca M Cunningham, Maureen A Walton

Journal Articles

The debate about whether measurement reactivity exists in daily diary research on substance use is still unsettled due to the issues of study design and statistical methodology. This study proposes a time-varying effect model (TVEM) that characterizes the trajectory of substance use behaviors with nonparametric functions determined by the data rather than imposes presumed parametric functions. It also allows researchers to investigate the effect of measurement reactivity on not only the likelihood of using substances but also the amount of substance use. The TVEM was applied to analyze diary data on alcohol and marijuana use collected from an experiment, which …
