Open Access Publications

Mass Drug Administration (MDA) programs to eliminate Lymphatic Filariasis (LF) in western Africa use the anthelminthics ivermectin plus albendazole. These drugs have the potential to impact also Soil-Transmitted Helminth (STH) infections, since the drugs have a broad range of anthelminthic activity. Integration of preventive chemotherapy efforts for LF, onchocerciasis and STH is recommended by the World Health Organization (WHO) in order to avoid duplication of MDA and to reduce costs. The objective of the current study was to determine whether five semi-annual rounds of community-wide MDA to eliminate LF and onchocerciasis have a greater impact on STH than three annual …

Developmental Changes In Myocardial B Cells Mirror Changes In B Cells Associated With Different Organs, Cibele Rocha-Resende, Wei Yang, Wenjun Li, Daniel Kreisel, Luigi Adamo, Douglas L Mann

Open Access Publications

The naive heart harbors a population of intravascular B cells that make close contact with the cardiac microvasculature. However, the timing of their appearance and their organ specificity remain unknown. To address this knowledge gap, we performed a systematic analysis of B cells isolated from the myocardium and other organs, from embryonic life to adulthood. We found that the phenotype of myocardial B cells changed dynamically during development. While neonatal heart B cells were mostly CD11b+ and CD11b- CD21-CD23-, adult B cells were predominantly CD11b-CD21+CD23+. Histological analysis and intravital microscopy of lung and liver showed that organ-associated B cells in …

Testing The Impact Of A Single Nucleotide Polymorphism In A Plasmodium Berghei Apiap2 Transcription Factor On Experimental Cerebral Malaria In Mice, Munir Akkaya, Abhisheka Bansal, Patrick W Sheehan, Mirna Pena, Clare K Cimperman, Chen Feng Qi, Takele Yazew, Thomas D Otto, Oliver Billker, Louis H Miller, Susan K Pierce

Open Access Publications

Cerebral malaria (CM) is the deadliest form of severe Plasmodium infections. Currently, we have limited understanding of the mechanisms by which Plasmodium parasites induce CM. The mouse model of CM, experimental CM (ECM), induced by infection with the rodent parasite, Plasmodium berghei ANKA (PbANKA) has been extensively used to study the pathophysiology of CM. Recent genomic analyses revealed that the coding regions of PbANKA and the closely related Plasmodium berghei NK65 (PbNK65), that does not cause ECM, differ in only 21 single nucleotide polymorphysims (SNPs). Thus, the SNP-containing genes might contribute to the pathogenesis of ECM. Although the majority of …

Selective Inhibition Of Mtorc1 In Tumor Vessels Increases Antitumor Immunity, Shan Wang, Ariel Raybuck, Eileen Shiuan, Sung Hoon Cho, Qingfei Wang, Dana M Brantley-Sieders, Deanna Edwards, Margaret M Allaman, James Nathan, Keith T Wilson, David Denardo, Siyuan Zhang, Rebecca Cook, Mark Boothby, Jin Chen

A tumor blood vessel is a key regulator of tissue perfusion, immune cell trafficking, cancer metastasis, and therapeutic responsiveness. mTORC1 is a signaling node downstream of multiple angiogenic factors in the endothelium. However, mTORC1 inhibitors have limited efficacy in most solid tumors, in part due to inhibition of immune function at high doses used in oncology patients and compensatory PI3K signaling triggered by mTORC1 inhibition in tumor cells. Here we show that low-dose RAD001/everolimus, an mTORC1 inhibitor, selectively targets mTORC1 signaling in endothelial cells (ECs) without affecting tumor cells or immune cells, resulting in tumor vessel normalization and increased antitumor …

Allergic disorders, characterized by Th2 immune responses to environmental substances, are increasingly common in children in Western societies. Multiple studies indicate that breastfeeding, early complementary introduction of food allergens, and antibiotic avoidance in the first year of life reduces allergic outcomes in at-risk children. Why the benefit of these practices is restricted to early life is largely unknown. We identified a preweaning interval during which dietary antigens are assimilated by the colonic immune system. This interval is under maternal control via temporal changes in breast milk, coincides with an influx of naive T cells into the colon, and is followed …

Sarm1 Acts Downstream Of Neuroinflammatory And Necroptotic Signaling To Induce Axon Degeneration, Kwang Woo Ko, Jeffrey Milbrandt, Aaron Diantonio

Open Access Publications

Neuroinflammation and necroptosis are major contributors to neurodegenerative disease, and axon dysfunction and degeneration is often an initiating event. SARM1 is the central executioner of pathological axon degeneration. Here, we demonstrate functional and mechanistic links among these three pro-degenerative processes. In a neuroinflammatory model of glaucoma, TNF-α induces SARM1-dependent axon degeneration, oligodendrocyte loss, and subsequent retinal ganglion cell death. TNF-α also triggers SARM1-dependent axon degeneration in sensory neurons via a noncanonical necroptotic signaling mechanism. MLKL is the final executioner of canonical necroptosis; however, in axonal necroptosis, MLKL does not directly trigger degeneration. Instead, MLKL induces loss of the axon survival …

Dopamine D2 Receptor Signaling On Imsns Is Required For Initiation And Vigor Of Learned Actions, Shana M Augustin, Gabriel C Loewinger, Timothy J O'Neal, Alexxai V Kravitz, David M Lovinger

Open Access Publications

Striatal dopamine D2 receptors (D2Rs) are important for motor output. Selective deletion of D2Rs from indirect pathway-projecting medium spiny neurons (iMSNs) impairs locomotor activities in a task-specific manner. However, the role of D2Rs in the initiation of motor actions in reward seeking and taking is not fully understood, and there is little information about how receptors contribute under different task demands and with different outcome types. The iMSN-D2Rs modulate neuronal activity and synaptic transmission, exerting control on circuit functions that may play distinct roles in action learning and performance. Selective deletion of D2Rs on iMSNs resulted in slower action initiation …

Tlr2/6 Signaling Promotes The Expansion Of Premalignant Hematopoietic Stem And Progenitor Cells In The Nup98-Hoxd13 Mouse Model Of Mds, Darlene A Monlish, Zev J Greenberg, Sima T Bhatt, Kathryn M Leonard, Molly P Romine, Qian Dong, Lauren Bendesky, Eric J Duncavage, Jeffrey A Magee, Laura G Schuettpelz

Open Access Publications

Toll-like receptor 2 (TLR2) expression is increased on hematopoietic stem and progenitor cells (HSPCs) of patients with myelodysplastic syndromes (MDS), and enhanced TLR2 signaling is thought to contribute to MDS pathogenesis. Notably, TLR2 heterodimerizes with TLR1 or TLR6, and while high TLR2 is associated with lower-risk disease, high TLR6, but not TLR1, correlates with higher-risk disease. This raises the possibility of heterodimer-specific effects of TLR2 signaling in MDS, and in the work described here, we tested the effects of specific modulation of TLR1/2 versus TLR2/6 signaling on premalignant HSPCs. Indeed, chronic stimulation of TLR2/6, but not TLR1/2, accelerates leukemic transformation …

A Cross-Reactive Antibody Protects Against Ross River Virus Musculoskeletal Disease Despite Rapid Neutralization Escape In Mice, Julie M. Fox, Ling Huang, Stephen Tahan, Laura A. Powell, James E. Crowe, David Wang, Michael S. Diamond

Open Access Publications

Arthritogenic alphaviruses cause debilitating musculoskeletal disease and historically have circulated in distinct regions. With the global spread of chikungunya virus (CHIKV), there now is more geographic overlap, which could result in heterologous immunity affecting natural infection or vaccination. Here, we evaluated the capacity of a cross-reactive anti-CHIKV monoclonal antibody (CHK-265) to protect against disease caused by the distantly related alphavirus, Ross River virus (RRV). Although CHK-265 only moderately neutralizes RRV infection in cell culture, it limited clinical disease in mice independently of Fc effector function activity. Despite this protective phenotype, RRV escaped from CHK-265 neutralization in vivo, with resistant variants …

Women with bacterial vaginosis (BV), an imbalance of the vaginal microbiome, are more likely to be colonized by potential pathogens such as Fusobacterium nucleatum, a bacterium linked with intrauterine infection and preterm birth. However, the conditions and mechanisms supporting pathogen colonization during vaginal dysbiosis remain obscure. We demonstrate that sialidase activity, a diagnostic feature of BV, promoted F. nucleatum foraging and growth on mammalian sialoglycans, a nutrient resource that was otherwise inaccessible because of the lack of endogenous F. nucleatum sialidase. In mice with sialidase-producing vaginal microbiotas, mutant F. nucleatum unable to consume sialic acids was impaired in vaginal colonization. …

Radiotherapy is a commonly used conditioning regimen for bone marrow transplantation (BMT). Cytotoxicity limits the use of this life-saving therapy, but the underlying mechanisms remain poorly defined. Here, we use the syngeneic mouse BMT model to test the hypothesis that lethal radiation damages tissues, thereby unleashing signals that indiscriminately activate the inflammasome pathways in host and transplanted cells. We find that a clinically relevant high dose of radiation causes severe damage to bones and the spleen through mechanisms involving the NLRP3 and AIM2 inflammasomes but not the NLRC4 inflammasome. Downstream, we demonstrate that gasdermin D (GSDMD), the common effector of …

Virus Infection Is Controlled By Hematopoietic And Stromal Cell Sensing Of Murine Cytomegalovirus Through Sting, Sytse J. Piersma, Jennifer Poursine-Laurent, Liping Yang, Glen N. Barber, Bijal A. Parikh, Wayne M. Yokoyama

Open Access Publications

Recognition of DNA viruses, such as cytomegaloviruses (CMVs), through pattern-recognition receptor (PRR) pathways involving MyD88 or STING constitute a first-line defense against infections mainly through production of type I interferon (IFN-I). However, the role of these pathways in different tissues is incompletely understood, an issue particularly relevant to the CMVs which have broad tissue tropisms. Herein, we contrasted anti-viral effects of MyD88 versus STING in distinct cell types that are infected with murine CMV (MCMV). Bone marrow chimeras revealed STING-mediated MCMV control in hematological cells, similar to MyD88. However, unlike MyD88, STING also contributed to viral control in non-hematological, stromal …

Transcriptional Profiling Reveals Altered Biological Characteristics Of Chorionic Stem Cells From Women With Gestational Diabetes, Liyun Chen, Chung-Teng Wang, Nicholas R Forsyth, Pensee Wu

Open Access Publications

BACKGROUND: Gestational diabetes (GDM) is a common complication of pregnancy. The impact of pregnancy complications on placental function suggests that extraembryonic stem cells in the placenta may also be affected during pregnancy. Neonatal tissue-derived stem cells, with the advantages of their differentiation capacity and non-invasive isolation processes, have been proposed as a promising therapeutic avenue for GDM management through potential cell therapy approaches. However, the influence of GDM on autologous stem cells remains unclear. Thus, studies that provide comprehensive understanding of stem cells isolated from women with GDM are essential to guide future clinical applications.

METHODS: Human chorionic membrane-derived stem …

Interleukin-22 Inhibits Respiratory Syncytial Virus Production By Blocking Virus-Mediated Subversion Of Cellular Autophagy, Sudipta Das, Claudette St Croix, Misty Good, Jie Chen, Jinming Zhao, Sanmei Hu, Mark Ross, Michael M Myerburg, Joseph M Pilewski, John Williams, Sally E Wenzel, Jay K Kolls, Anuradha Ray, Prabir Ray

Open Access Publications

Respiratory syncytial virus (RSV) infection can cause severe bronchiolitis in infants requiring hospitalization, whereas the elderly and immunocompromised are prone to RSV-induced pneumonia. RSV primarily infects lung epithelial cells. Given that no vaccine against RSV is currently available, we tested the ability of the epithelial-barrier protective cytokine interleukin-22 (IL-22) to control RSV production. When used in a therapeutic modality, IL-22 efficiently blunted RSV production from infected human airway and alveolar epithelial cells and IL-22 administration drastically reduced virus titer in the lungs of infected newborn mice. RSV infection resulted in increased expression of LC3B, a key component of the cellular …

Open Access Publications

BACKGROUND: Environmental enteric dysfunction (EED) is an enigmatic disorder of the small intestine that is postulated to play a role in childhood undernutrition, a pressing global health problem. Defining the incidence of this disorder, its pathophysiological features, and its contribution to impaired linear and ponderal growth has been hampered by the difficulty in directly sampling the small intestinal mucosa and microbial community (microbiota).

METHODS: In this study, among 110 young children (mean age, 18 months) with linear growth stunting who were living in an urban slum in Dhaka, Bangladesh, and had not benefited from a nutritional intervention, we performed endoscopy …

Preterm Intraventricular Hemorrhage In Vitro: Modeling The Cytopathology Of The Ventricular Zone, Leandro Castaneyra-Ruiz, James P Mcallister, Diego M Morales, Steven L Brody, Albert M Isaacs, David D Limbrick

Open Access Publications

BACKGROUND: Severe intraventricular hemorrhage (IVH) is one of the most devastating neurological complications in preterm infants, with the majority suffering long-term neurological morbidity and up to 50% developing post-hemorrhagic hydrocephalus (PHH). Despite the importance of this disease, its cytopathological mechanisms are not well known. An in vitro model of IVH is required to investigate the effects of blood and its components on the developing ventricular zone (VZ) and its stem cell niche. To address this need, we developed a protocol from our accepted in vitro model to mimic the cytopathological conditions of IVH in the preterm infant.

METHODS: Maturing neuroepithelial …

Selective Dorsal Rhizotomy For The Treatment Of Spastic Triplegic Cerebral Palsy, T. S. Park, Susan Joh, Deanna M. Walter, Matthew B. Dobbs

Open Access Publications

Background Spastic triplegia is a recognized subtype of cerebral palsy (CP). In the course of treating spastic triplegic children with selective dorsal rhizotomy (SDR), we found that some children who had "minimal or mild involvement" in the stronger arm improved strikingly after undergoing SDR. Some of them became independent ambulators, which was an outcome that is not usually achieved in spastic quadriplegic children. However, the literature currently contains no data on the natural clinical course and the effects of CP interventions on spastic triplegia. Objectives Our aim was to elucidate the clinical characteristics of spastic triplegia and the effects of …

Cross-Serotype Protection Against Group A Streptococcal Infections Induced By Immunization With Spy_2191, Pooja Sanduja, Manish Gupta, Vikas Kumar Somani, Vikas Yadav, Meenakshi Dua, Emanuel Hanski, Abhinay Sharma, Rakesh Bhatnagar, Atul Kumar Johri

Open Access Publications

Group A Streptococcus (GAS) infection causes a range of diseases, but vaccine development is hampered by the high number of serotypes. Here, using reverse vaccinology the authors identify SPy_2191 as a cross-protective vaccine candidate. From 18 initially identified surface proteins, only SPy_2191 is conserved, surface-exposed and inhibits both GAS adhesion and invasion. SPy_2191 immunization in mice generates bactericidal antibodies resulting in opsonophagocytic killing of prevalent and invasive GAS serotypes of different geographical regions, including M1 and M49 (India), M3.1 (Israel), M1 (UK) and M1 (USA). Resident splenocytes show higher interferon-γ and tumor necrosis factor-α secretion upon antigen re-stimulation, suggesting activation …

Fam20b-Catalyzed Glycosaminoglycans Control Murine Tooth Number By Restricting Fgfr2b Signaling, Jingyi Wu, Ling Li, David M Ornitz, Et Al

Open Access Publications

BACKGROUND: The formation of supernumerary teeth is an excellent model for studying the molecular mechanisms that control stem/progenitor cell homeostasis needed to generate a renewable source of replacement cells and tissues. Although multiple growth factors and transcriptional factors have been associated with supernumerary tooth formation, the regulatory inputs of extracellular matrix in this regenerative process remains poorly understood.

RESULTS: In this study, we present evidence that disrupting glycosaminoglycans (GAGs) in the dental epithelium of mice by inactivating FAM20B, a xylose kinase essential for GAG assembly, leads to supernumerary tooth formation in a pattern reminiscent of replacement teeth. The dental epithelial …

Taf15 Contributes To The Radiation-Inducible Stress Response In Cancer, Abhay Kumar Singh, Vaishali Kapoor, Dinesh Thotala, Dennis E. Hallahan

Open Access Publications

Resistance to radiation therapy is a significant problem in the treatment of non-small cell lung cancer (NSCLC). There is an unmet need to discover new molecular targets for drug development in combination with standard of care cancer therapy. We found that TAF15 was radiation-inducible using phage-displayed peptide libraries. In this study, we report that overexpression of TAF15 is correlated with worsened survival in NSCLC patients. Radiation treatment led to surface induction of TAF15

Epigenomics And Genotype-Phenotype Association Analyses Reveal Conserved Genetic Architecture Of Complex Traits In Cattle And Human, Shuli Liu, Ying Yu, Shengli Zhang, John B Cole, Albert Tenesa, Ting Wang, Tara G Mcdaneld, Li Ma, George E Liu, Lingzhao Fang

Open Access Publications

BACKGROUND: Lack of comprehensive functional annotations across a wide range of tissues and cell types severely hinders the biological interpretations of phenotypic variation, adaptive evolution, and domestication in livestock. Here we used a combination of comparative epigenomics, genome-wide association study (GWAS), and selection signature analysis, to shed light on potential adaptive evolution in cattle.

RESULTS: We cross-mapped 8 histone marks of 1300 samples from human to cattle, covering 178 unique tissues/cell types. By uniformly analyzing 723 RNA-seq and 40 whole genome bisulfite sequencing (WGBS) datasets in cattle, we validated that cross-mapped histone marks captured tissue-specific expression and methylation, reflecting tissue-relevant …

Open Access Publications

BACKGROUND: Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive soft tissue sarcomas with high metastatic rates and poor overall patient survival. There are currently no effective therapies, underscoring the pressing need to define the molecular etiologies that underlie MPNST progression. The aim of this study was to examine clonal progression and identify the molecular events critical for MPNST spread.

METHODS: In two patients with temporally and spatially distinct metastatic lesions, we employed whole exome sequencing (WES) to elucidate the genetic events of clonal progression, thus identifying the molecular events critical for MPNST spread.

RESULTS: First, we demonstrated shared clonal origins …

Histopathology And Selective Biomarker Expression In Human Meibomian Glands, Lixing W Reneker, Rebecca T Irlmeier, Ying-Bo Shui, Ying Liu, Andrew J W Huang

Open Access Publications

BACKGROUND/AIMS: Meibomian gland dysfunction (MGD) is the most common form of evaporative dry eye disease, but its pathogenesis is poorly understood. This study examined the histopathological features of meibomian gland (MG) tissue from cadaver donors to identify potential pathogenic processes that underlie MGD in humans.

METHODS: Histological analyses was performed on the MGs in the tarsal plates dissected from four cadaver donors, two young and two old adults, including a 36-year-old female (36F) and three males aged 30, 63 and 64 years (30M, 63M and 64M).

RESULTS: The MGs of 36F displayed normal anatomy and structure, whereas the MGs of …

Open Access Publications

OBJECTIVE: Distal sensory polyneuropathy (DSP) and neuropathic pain are important clinical concerns in virally suppressed people with HIV. We determined how these conditions evolved, what factors influenced their evolution, and their clinical impact.

METHODS: Ambulatory, community-dwelling HIV seropositive individuals were recruited at six research centers. Clinical evaluations at baseline and 12 years later determined neuropathy signs and distal neuropathic pain (DNP). Additional assessments measured activities of daily living and quality of life (QOL). Factors potentially associated with DSP and DNP progression included disease severity, treatment, demographics, and co-morbidities. Adjusted odds ratios were calculated for follow-up neuropathy outcomes.

RESULTS: Of 254 …

Comparative Genomics And Transcriptomics Of 4 Paragonimus Species Provide Insights Into Lung Fluke Parasitism And Pathogenesis, Bruce A. Rosa, Young-Jun Choi, Samantha N. Mcnulty, Hyeim Jung, John Martin, Takeshi Agatsuma, Hiromu Sugiyama, Thanh Hoa Le, Pham Ngoc Doanh, Wanchai Maleewong, David Blair, Paul J. Brindley, Peter U. Fischer, Makedonka Mitreva

Open Access Publications

BACKGROUND: Paragonimus spp. (lung flukes) are among the most injurious foodborne helminths, infecting ∼23 million people and subjecting ∼292 million to infection risk. Paragonimiasis is acquired from infected undercooked crustaceans and primarily affects the lungs but often causes lesions elsewhere including the brain. The disease is easily mistaken for tuberculosis owing to similar pulmonary symptoms, and accordingly, diagnostics are in demand.

RESULTS: We assembled, annotated, and compared draft genomes of 4 prevalent and distinct Paragonimus species: Paragonimus miyazakii, Paragonimus westermani, Paragonimus kellicotti, and Paragonimus heterotremus. Genomes ranged from 697 to 923 Mb, included 12,072-12,853 genes, and were 71.6-90.1% complete according …
