The Role of Traf6 Phosphorylation In Src/Traf6-Mediated Ikk, Jnk, Akt Activation and Tumorigenesis
<p>TRAF6 E3 ligase regulates numerous essential biological processes such as innate immune response, cell survival and osteoclast differentiation. Upon activation, it mediates activation of IKK/NF-κB and JNK signaling in response to engagement of toll-like receptor 4 (TLR4), interleukin-1 receptor …

Determining the Roles of Q-SNAREs in Mast Cell Tumor Necrosis Factor Exocytosis
… accumulates on the contributions of mast cell function to the development of allergic disorders, cardiovascular and neurological pathologies, and cancers, there is a growing recognition of the importance of mast cell-derived TNF to mast cell-mediated pathophysiology. However, our …

Gliotoxin Production in Aspergillus fumigatus
… of patients undergoing immunosuppressive therapy and receiving organ transplants (Bok et al. 2006). Although there is still disagreement as to the causative agent of the symptoms accompanying aspergillosis, many scientists suspect that the compound, gliotoxin, plays a major role, hi this study, we …

Bhlhe40: Required For Tumor Microenvironment Remodeling and Immune Checkpoint Therapy Efficacy
… immune checkpoints to control effector T cell functions(Pardoll, 2012). This therapy allows for the modulation of anti-tumor responses through the use of monoclonal antibodies, such as anti-CTLA-4 or anti-PD-1 that block the receptors from binding with their ligands, thus allowing for …

Defining The Role of Il-15 Trans-Presentation By Distinct Cell-Types During The Development and Homeostasis of Natural Killer and Invariant Natural Killer T Cells
The immuno-regulatory functions displayed by NK and iNKT cells have highlighted their importance as key lymphocytes involved in innate and adaptive immunity. Therefore, understanding the dynamics influencing the generation of NK and iNKT cells is extremely important. IL-15 has been shown to provide …

Prelamin A Influences a Program of Gene Expression In Regulation of Cell Cycle Control
… of the inner nuclear membrane, providing shape and structural integrity to the nucleus. Lamin A (LA) filaments also permeate the nucleoplasm, providing additional structural support, but also scaffolding numerous tethered molecules to stabilize, organize, and facilitate molecular interactions to …

Endosomal Trafficking as a Determinant of Antifungal Tolerance in the Pathogenic Fungus Candida albicans
… a lipid that modulates the thickness, fluidity and permeability of fungal cell membranes. These include the azole antifungals, which block ergosterol biosynthesis by inhibiting lanosterol demethylase (Erg11p). The resulting depletion of cellular ergosterol and the accumulation of ‘toxic’ sterol …

The Effect of Diet on Neutrophilic Phagocytosis
… from 6 to 8 subjects were drawn at fasting, and at various time periods following ingestion of 12.5, 25, 50, 75, and 100 grams of glucose. In the second series of experiments, blood samples were taken from 11 subjects after an overnight fast and 2 hours following ingestion of one of 4 …

Endogenous Mechanisms Regulating Myeloid Cell Mediated Inflammation During Acute Lung Injuries
… for patients are limited to supportive care and novel approaches are urgently needed. Appreciating the role of excessive inflammation that underlies the pathophysiology of ALI, we sought to identify endogenous mechanisms that dampen inflammation. Here we investigated two pathways that worked …

IL-1β Amplification of Nitric Oxide Production and Its Inhibitory Effects on Glucose Induced Early Growth Response-1 Expression in INS-1 Cells
… cytokines released by infiltrating white blood cells upon pancreatic beta cells is not fully understood. Early growth response gene-1 (Egr-1) expression is specifically and transiently up regulated in pancreatic beta cells in response to glucose. We hypothesized that interleukin-1 beta (IL-1▀) …

The Effect of Endothelin-1 on the expression of CDK Inhibitors p21 & p27 in Bovine Corneal Endothelial Cells
Mammalian corneal endothelial cells are considered to be non-proliferative due to the arrest of cells at the G1 phase of the cell cycle. The purpose of this study was to determine whether the down regulation of cyclin dependant kinase inhibitors (p21cip1 and p27kip1) levels by Endothelin-1 (ET-1), …
