The bi-directional relationship between gut microbiota and autoimmunity
<p>Humans serve as a major reservoir for a vast number of microbiota. These microbes have evolved symbiotic relationships with humans due to their close proximity with their host. As a result, the immune system adapts to the microbiota thus modulating immunological function. Autoimmunity is a state …

Effects of Acute Heat and Oxidative Stress on the Hepatic Expression of Orexin and Its Related Receptors
<p>It is widely known that orexin A and B peptides as well as their receptors are expressed in the hypothalamus and distributed throughout the central nervous system, but there have been few studies regarding its presences in other parts of the body. There is now evidence that orexin (ORX) and its …

Exploring the Physiological Role of Vibrio fischeri PepN
<p>The primary contributor to Vibrio fischeri aminopeptidase activity is aminopeptidase N, PepN. Colonization assays revealed the pepN mutant strain to be deficient at forming dense aggregates and populating the host’s light organ compared to wildtype within the first 12 hours of colonization; …

The Thioredoxin Trx-1 Regulates The Major Oxidative Stress Response Transcription Factor, Skn-1, In Caenorhabditis Elegans
… unresolved, can lead to cellular dysfunction and organismal disease. Sophisticated detoxification systems, characterized by a battery of enzymatic antioxidants, are utilized to neutralize ROS thereby reducing stress. However, ROS are also purposefully produced by designated cellular enzymes to …

Characterization of Ftsa-Ftsn Interaction During Escherichia Coli Cell Division
<p>Division of a bacterial cell into two equal daughter cells requires precise assembly and constriction of the division machinery, or divisome. The <em>Escherichia coli </em>divisome includes nearly a dozen essential cell division proteins that assemble at midcell between segregating sister …

Regulation of the Tubulin Homolog FtsZ in <i>Escherichia coli</i>
… a widely used model organism in all fields of biological sciences for cloning, protein purification, and as a model for Gram-negative bacterial species. And yet, researchers do not fully understand how this bacterium replicates and divides. Every year additional division proteins are …
