Our study provides novel evidence that young adult women with moderate-to-severe adverse childhood experience (ACE) exposure present impaired endothelial function and lower circulating sirtuin 1 (SIRT1) concentrations than age-matched controls. However, an 8-wk exercise intervention was unable to augment or SIRT1 in a subset of those ACEs. data suggest ACEs-related impairments may be secondary decreased NO bioavailability via and/or oxidative stress-related mechanisms.

CD27 and CD28 have emerged as indicators demarcating the transition of thymocytes through β-selection. We found that exhibits a greater dynamic range expression during this phase, thus it was employed to further parse DN/CD44− compartment in order assess IL-7 signaling β-selection process. Plotting versus CD25 revealed six populations. OP9-DL1 stromal cell co-culture used demonstrate developmental linkage from DN3a (CD25+CD28−/lo) DN3b (CD25+CD28+) DN3c (CD25intCD28+) DN4a (CD25−CD28+)...

This randomized controlled pilot trial shows, for the first time, that 8 wk of structured, progressive exercise training lowers serum endothelin-1 (ET-1) and improves positive psychological coping in young women with significant early-life psychosocial stress. Furthermore, observed associations among changes attributes, ET-1, systolic blood pressure signify a potential interplay between psychology cardiovascular disease risk adverse childhood experiences.

Although IL-18 has not previously been shown to promote T lymphopoiesis, results obtained via a novel data mining algorithm (global microarray meta-analysis) led us explore predicted role for this cytokine in cell development. is member of the IL-1 family that extensively characterized as mediator inflammatory immune responses. To assess potential development, we sort-purified mouse bone marrow-derived common lymphoid progenitor cells, early thymic progenitors (ETPs), and double-negative 2...

Thymocyte development is accompanied by sequential changes in cell surface glycosylation. For example, medullary thymocytes have increased levels of alpha2,3-linked sialic acid and a loss asialo core 1 O-glycans as compared to cortical thymocytes. Some these been linked fine tuning the T receptor avidity. We analyzed ST6Gal I transcript abundance alpha2,6-linked across thymocyte subsets. found that following beta-selection suggesting this sialyltransferase may influence early populations....

We have developed a 12-parameter/10-color flow cytometric staining method for the simultaneous detection and characterization of 21 mouse thymocyte subpopulations that represent discreet stages T cell development. To demonstrate utility this method, we assessed cytokine receptor expression on subsets. These experiments revealed distinct patterns surface receptors cytokines IL-4 IL-6.The α chain (CD124) was highly expressed earliest subsets, then downregulated prior to β-selection finally...

This study utilized suppressive subtractive hybridization between the clinical isolate Burkholderia cenocepacia J2315 and closely related environmental cepacia ATCC 25416 T to DNA fragments specific B. J2315. Analysis of resulting pools -specific DNAs identified several that may be part putative virulence factors. Further in silico analysis a single fragment indicated it was internal gene which predicted product had characteristics repeat toxin (RTX)-like proteins high similarity other human...

Introduction: Early life psychosocial stress and adversity - referred to as adverse childhood experiences (ACEs) are highly prevalent, with ~60% of American adults reporting exposure at least one ACE. ACEs occur during critical developmental periods related cardiovascular morbidity mortality in a graded, dose-dependent manner. Sleep is an emerging lifestyle behavior that has been associated cardiometabolic mortality, poor sleep ACEs. Hypothesis: We hypothesized would be disrupted altered...

Introduction: Adverse Childhood Experiences (ACEs), in the forms of abuse, neglect, and violence, are associated with augmented blood pressures young adulthood CVD risk later life. These effects independent negative health behaviors, suggesting that ACEs biologically embedded. Sirtuin 1 (SIRT1) is a highly conserved nicotinamide-adenine dinucleotide-dependent deacetylase plays an important role regulation vascular function aerobic organisms, while endothelial dysfunction antecedent overt...

Abstract Determining the most effective parameters for in vitro propagation of T cell precursors is critical realizing promise many envisioned cell-based immunotherapies. To this end, consequences culturing ETP and DN2 thymocytes with IL-18 IL-1β context OP9-DL4 co-culture model were evaluated after inference a hypothesized role these molecules thymopoiesis based on results obtained via novel microarray/literature mining algorithm. Sort-purified mouse ETPs cultured stromal layers ±IL-18,...

Abstract We have developed a 10 color flow cytometric staining protocol for the simultaneous detection and characterization of 21 thymocyte subpopulations. These subpopulations include 17 previously described subsets 4 new subsets. Importantly, this methodology uses only commercially available monoclonal antibodies therefore could be easily employed by any investigator with access to standard laser cytometer. Using novel scheme we analyzed mouse thymocytes at discreet stages development...

Abstract Common lymphoid progenitors derived from murine bone marrow have previously been demonstrated to be capable of long-term propagation in OP9-DL1 co-cultures. Cultures this type initially display a wave differentiation the double positive stage T cell development that is observable at three four weeks post-culture initiation. Continued eventually produces heterogeneous population cells collectively resemble thymocytes animals incapable β-selection. As TCRβ gene rearrangement occurs...

CD27 and CD28 have been used within the traditional thymic DN3 compartment to distinguish β-selected cells. The CD27hi CD28hi cells represent same population we find that use of expression status in thymocyte development scheme provides a means clearly subdivide contemporary into three developmentally ordered populations. DN3a DN3b thymocytes pre-β-selected immediately post-β-selected thymocytes, respectively, differentiated on basis (DN3aCD28–/lo DN3bCD28hi) while DN3c (discriminated based...

Adverse childhood experiences (ACEs) represent psychosocial stressors that occur during critical developmental periods and are associated in a dose-dependent manner with adverse cardiovascular outcomes emerging adults, including greater age-related increases blood pressure (BP) increased circulating endothelin-1 (ET-1), stress-responsive, endothelium-derived peptide potent vasoconstrictor. ACEs have also been linked to lower resilience hope, which is motivational state based on goal-directed...
