An inflammatory checkpoint regulates recruitment of graft-versus-host reactive T cells to peripheral tissues

Transfer of T cells to freshly irradiated allogeneic recipients leads to their rapid recruitment to nonlymphoid tissues, where they induce graft-versus-host disease (GVHD). In contrast, when donor T cells are transferred to established mixed chimeras (MCs), GVHD is not induced despite a robust graft-versus-host (GVH) reaction that eliminates normal and malignant host hematopoietic cells. We demonstrate here that donor GVH-reactive T cells transferred to MCs or freshly irradiated mice undergo similar expansion and activation, with similar up-regulation of homing molecules required for entry to nonlymphoid tissues. Using dynamic two-photon in vivo microscopy, we show that these activated T cells do not enter GVHD target tissues in established MCs, contrary to the dogma that activated T cells inevitably traffic to nonlymphoid tissues. Instead, we show that the presence of inflammation within a nonlymphoid tissue is a prerequisite for the trafficking of activated T cells to that site. Our studies help to explain the paradox whereby GVH-reactive T cells can mediate graft-versus-leukemia responses without inducing GVHD in established MCs

Effect of Providing Conditional Economic Compensation on Uptake of Voluntary Medical Male Circumcision in Kenya: A Randomized Clinical Trial

Novel strategies are needed to increase the uptake of voluntary medical male circumcision (VMMC) in sub-Saharan Africa and enhance the effectiveness of male circumcision as an HIV prevention strategy

Ghana’s HIV epidemic and PEPFAR’s contribution towards epidemic control

Background: The aim of this review was to summarize the data on HIV/AIDS epidemiology and affected populations in Ghana and to describe the United States President’s Emergency Plan for Emergency Relief’s (PEPFAR) response to the epidemic. Design: We conducted a literature review focusing on PEPFAR’s contribution to the HIV response in Ghana. Additionally, we summarized the epidemiology of HIV. We searched both peer-reviewed and grey literature. Setting: Ghana Results: Overall, HIV prevalence in Ghana is 1.6% with regional variation. Key populations (KPs) are disproportionately affected by HIV in the country. FSW and their clients, and MSM, account for 28% of all new infections. PEPFAR provides technical assistance (TA) to Ghana to maximize the quality, coverage and impact of the national HIV/AIDS response. To ensure adequate supply of antiretrovirals (ARVs), in 2016-2017, PEPFAR invested $23.7 million as a onetime supplemental funding to support Ghana’s ARV treatment program. In addition, the National AIDS Control Programme in collaboration with PEPFAR is implementing a scale up of viral load testing. PEPFAR is also implementing a comprehensive package of prevention services in five regions to help reach MSM and FSW and to expand HIV testing services for KPs. Conclusions: Ghana is making changes at both policy and program level in the fight against HIV/AIDS and is working towards achieving the UNAIDS’ 90-90-90 targets. PEPFAR is providing TA to ensure these goals can be achieved. Funding: This manuscript has been supported by the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR) through the Centers for Disease Control and Prevention (CDC). Keywords: HIV, epidemic, Ghana, PEPFA

Gender differences in behavioral regulation in four societies: The United States, Taiwan, South Korea, and China

The current study investigates gender differences in behavioral regulation in four societies: the United States, Taiwan, South Korea, and China. Directly assessed individual behavioral regulation (Head–Toes–Knees–Shoulders, HTKS), teacher-rated classroom behavioral regulation (Child Behavior Rating Scale, CBRS) and a battery of school readiness assessments (mathematics, vocabulary, and early literacy) were used with 814 young children (ages 3–6 years). Results showed that girls in the United States had significantly higher individual behavioral regulation than boys, but there were no significant gender differences in any Asian societies. In contrast, teachers in Taiwan, South Korea, as well as the United States rated girls as significantly higher than boys on classroom behavioral regulation. In addition, for both genders, individual and classroom behavioral regulation were related to many aspects of school readiness in all societies for girls and boys. Universal and culturally specific findings and their implications are discussed

Brf1 loss and not overexpression disrupts tissues homeostasis in the intestine, liver and pancreas

RNA polymerase III (Pol-III) transcribes tRNAs and other small RNAs essential for protein synthesis and cell growth. Pol-III is deregulated during carcinogenesis; however, its role in vivo has not been studied. To address this issue, we manipulated levels of Brf1, a Pol-III transcription factor that is essential for recruitment of Pol-III holoenzyme at tRNA genes in vivo. Knockout of Brf1 led to embryonic lethality at blastocyst stage. In contrast, heterozygous Brf1 mice were viable, fertile and of a normal size. Conditional deletion of Brf1 in gastrointestinal epithelial tissues, intestine, liver and pancreas, was incompatible with organ homeostasis. Deletion of Brf1 in adult intestine and liver induced apoptosis. However, Brf1 heterozygosity neither had gross effects in these epithelia nor did it modify tumorigenesis in the intestine or pancreas. Overexpression of BRF1 rescued the phenotypes of Brf1 deletion in intestine and liver but was unable to initiate tumorigenesis. Thus, Brf1 and Pol-III activity are absolutely essential for normal homeostasis during development and in adult epithelia. However, Brf1 overexpression or heterozygosity are unable to modify tumorigenesis, suggesting a permissive, but not driving role for Brf1 in the development of epithelial cancers of the pancreas and gut

Drag Queen Discourse: Social Circulation, Restorative Literacies, and Rhetorical Space

This project explores three different forms of discourse in American drag queen culture. It seeks to understand different ways that drag queen culture heals itself, is misrepresented in modern media, and how drag discourse is an opportunity to engage in public learning. By employing rhetorical methods of social circulation, restorative healing, and rhetorical space, it becomes clear that drag queen culture has much to offer the field of composition and rhetoric in that it is a largely unexplored discourse in Queer and cultural rhetorics

United States marriage, the wedding industry and neoliberalism

Within US culture marriage, has become associated with one event, a wedding. Social and economic policies implemented by the US government normalize marriage in American society. Marriage is perpetuated and institutionalized through the cultural norms associated with marriage and weddings. This has led to a continuously growing wedding industry that currently flourishes and is expanding globally. The global expansion of the US wedding industry is found in the overseas production of goods that are consumed for US weddings. Marriage, weddings and neoliberalism become bound together by American policies and institutions that stress marriage, traditional gender norms and free market capitalism. My research seeks to examine three overarching questions on the connections between US neoliberal policies and ideologies, marriage, the accompanying wedding industry and women laborers globally. First, how the domestic policies implemented by the US perpetuate the institution of marriage as normal and reinforce marriage in American culture. Secondly, how is the US wedding industry’s development and expansion tied to the proliferation of neoliberal capitalism? Finally, because the majority of goods for the American wedding industry are produced globally, how the consumption of these goods for US weddings affects women laborers globally. In the conclusion I will discuss possible policy solutions for these overarching issues. To examine these connections, I will analyze heterosexual marriage norms, public policies, neoliberal capitalism, and sweatshop labor

An Essential Role for IFN-γ in Regulation of Alloreactive CD8 T Cells Following Allogeneic Hematopoietic Cell Transplantation

AbstractWe previously found that CD8 T cells from IFN-γ gene knockout (GKO) donors induce more severe lethal GVHD compared with CD8 T cells from wild-type (WT) donors in fully MHC-mismatched strain combinations. In this study, we investigated the mechanisms by which IFN-γ inhibits GVHD in a parent → F1 (B6 → B6D2F1) allogeneic HCT (allo-HCT) model. IFN-γ was strongly protective against GVHD in this parent → F1 haplotype-mismatched allo-HCT model. Irradiated B6D2F1 mice that received GKO B6 CD4-depleted splenocytes developed lethal GVHD with severe lung and liver injury, whereas those receiving a similar cell population from WT B6 donors survived long term. Donor CD8 cells showed rapid activation, accelerated cell division, and reduced/delayed activation-induced cell death in allogeneic recipients in which donor cells were incapable of producing IFN-γ. In consequence, the numbers of activated/effector (ie, CD25+, CD62L−, and CD44high) donor CD8 T cells in the recipients of GKO allo-HCT significantly exceeded those in mice receiving WT allo-HCT. These data show that IFN-γ negatively regulates the CD8 T cell response by inhibiting cell division and promoting cell death and suggest that blockade of IFN-γ could augment the severity of GVHD in patients undergoing allo-HCT
