Safety Considerations When Working with Humanized Animals.

ILAR J 2018 Dec 12. Epub 2018 Dec 12.

Unit for Laboratory Animal Medicine, University of Michigan Medical School in Ann Arbor, Michigan.

Research using laboratory animals has been revolutionized by the creation of humanized animal models, which are immunodeficient animals engrafted with human cells, tissues, or organs. These animal models provide the research community a unique and promising opportunity to mimic a wide variety of disease conditions in humans, from infectious disease to cancer. A vast majority of these models are humanized mice like those injected with human CD34+ hematopoietic stem cells and patient-derived xenografts. Read More

Magnitude of Therapeutic STING Activation Determines CD8 T Cell-Mediated Anti-tumor Immunity.

Cell Rep 2018 Dec;25(11):3074-3085.e5

Aduro Biotech, Inc., Berkeley, CA 94710, USA. Electronic address:

Intratumoral (IT) STING activation results in tumor regression in preclinical models, yet factors dictating the balance between innate and adaptive anti-tumor immunity are unclear. Here, clinical candidate STING agonist ADU-S100 (S100) is used in an IT dosing regimen optimized for adaptive immunity to uncover requirements for a T cell-driven response compatible with checkpoint inhibitors (CPIs). In contrast to high-dose tumor ablative regimens that result in systemic S100 distribution, low-dose immunogenic regimens induce local activation of tumor-specific CD8 effector T cells that are responsible for durable anti-tumor immunity and can be enhanced with CPIs.

IGFBP7 Induces Differentiation and Loss of Survival of Human Acute Myeloid Leukemia Stem Cells without Affecting Normal Hematopoiesis.

Cell Rep 2018 Dec;25(11):3021-3035.e5

Department of Hematology, Cancer Center Amsterdam (CCA), Amsterdam UMC, VU Medical Center, Amsterdam, the Netherlands. Electronic address:

Leukemic stem cells (LSCs) are thought to be the major cause of the recurrence of acute myeloid leukemia (AML) due to their potential for self-renewal. To identify therapeutic strategies targeting LSCs, while sparing healthy hematopoietic stem cells (HSCs), we performed gene expression profiling of LSCs, HSCs, and leukemic progenitors all residing within the same AML bone marrow and identified insulin-like growth factor-binding protein 7 (IGFBP7) as differentially expressed. Low IGFBP7 is a feature of LSCs and is associated with reduced chemotherapy sensitivity. Read More

Heterogeneous Responses of Hematopoietic Stem Cells to Inflammatory Stimuli Are Altered with Age.

Cell Rep 2018 Dec;25(11):2992-3005.e5

Division of Biology and Biological Engineering, California Institute of Technology, Pasadena, CA 91125, USA. Electronic address:

Long-term hematopoietic stem cells (LT-HSCs) maintain hematopoietic output throughout an animal's lifespan. However, with age, the balance is disrupted, and LT-HSCs produce a myeloid-biased output, resulting in poor immune responses to infectious challenge and the development of myeloid leukemias. Here, we show that young and aged LT-HSCs respond differently to inflammatory stress, such that aged LT-HSCs produce a cell-intrinsic, myeloid-biased expression program. Read More

Improved multilineage human hematopoietic reconstitution and function in NSGS mice.

PLoS One 2018 12;13(12):e0209034. Epub 2018 Dec 12.

Division of Experimental Hematology and Cancer Biology, Cancer and Blood Disease Institute, Cincinnati Children's Hospital Medical Center, Cincinnati, Ohio, United States of America.

Genetic manipulation of NOD/SCID (NS) mice has yielded numerous sub-strains with specific traits useful for the study of human hematopoietic xenografts, each with unique characteristics. Here, we have compared the engraftment and output of umbilical cord blood (UCB) CD34+ cells in four immune-deficient strains: NS, NS with additional IL2RG knockout (NSG), NS with transgenic expression of human myeloid promoting cytokines SCF, GM-CSF, and IL-3 (NSS), and NS with both IL2RG knockout and transgenic cytokine expression (NSGS). Overall engraftment of human hematopoietic cells was highest in the IL2RG knockout strains (NSG and NSGS), while myeloid cell output was notably enhanced in the two strains with transgenic cytokine expression (NSS and NSGS).

CD47 expression is decreased in hematopoietic progenitor cells in patients with myelofibrosis.

Braz J Med Biol Res 2018 Dec 10;52(1):e7784. Epub 2018 Dec 10.

Sabin Medicina Diagnóstica, Brasília, DF, Brasil.

Myelofibrosis (MF) is characterized by increased circulating hematopoietic progenitor cells (HPCs), abnormal cytokine levels, and the survival advantage of neoplastic progenitors over their normal counterparts, which leads to progressive disappearance of polyclonal hematopoiesis. CD47 is a surface glycoprotein with many functions, such as acting as a phagocytosis inhibitor of the expressing cell, that is increased in normal hematopoietic stem and progenitor cells mobilized into the blood and several human cancer-initiating cells, such as in acute myeloid leukemia. We compared CD47 expression in hematopoietic stem and progenitor cells of patients with MF and controls and found it to be decreased in progenitors of MF. Read More

Isolation and Identification of Murine Bone Marrow-Derived Macrophages and Osteomacs from Neonatal and Adult Mice.

Methods Mol Biol 2018 Dec 12. Epub 2018 Dec 12.

Department of Medicine, Indiana University School of Medicine, Indianapolis, IN, USA.

Hematopoietic stem cells (HSCs) are regulated by multiple components of the hematopoietic niche, including bone marrow-derived macrophages and osteomacs. However, both macrophages and osteomacs are phenotypically similar. Thus, specific phenotypic markers are required to differentially identify the effects of osteomacs and bone marrow macrophages on different physiological processes, including hematopoiesis and bone remodeling.

Donor-derived hepatocytes in human hematopoietic cell transplant recipients: evidence of fusion.

Virchows Arch 2018 Dec 12. Epub 2018 Dec 12.

Clinical Research Division, Fred Hutchinson Cancer Research Center, 1100 Fairview Ave. N, Seattle, WA, 98109, USA.

Reconstitution of hepatocytes by hematopoietic stem cells-a phenomenon which occurs in rodents under highly selective conditions-results from infrequent fusion between incoming myelomonocytes and host hepatocytes, with subsequent proliferation. Human hematopoietic stem cell transplant recipients have been little studied, with some support for transdifferentiation (direct differentiation). We studied routinely obtained autopsy liver tissue of four female hematopoietic cell transplant recipients with male donors, using a highly specific conjoint immunohistochemistry in situ hybridization light microscopic technique.

Drugs Today (Barc) 2018 Nov;54(11):679-693

Tech Micro Services, Bethesda, Maryland, USA.

The potential use by terrorists of an improvised nuclear device, a radiological dispersal device, or an unintended nuclear/radiological accident in heavily populated areas is a national security threat of major consequences. Although this type of security threat is considered to be low-risk, it would have a devastating impact. Health issues would be a major concern; medical care would be necessary for all those who received considerable radiation exposure (> 1 Gy) leading to hematopoietic acute radiation syndrome (ARS).

The IL-15-AKT-XBP1s signaling pathway contributes to effector functions and survival in human NK cells.

Nat Immunol 2019 Jan 10;20(1):10-17. Epub 2018 Dec 10.

The Ohio State University Comprehensive Cancer Center, Columbus, OH, USA.

Interleukin 15 (IL-15) is one of the most important cytokines that regulate the biology of natural killer (NK) cells. Here we identified a signaling pathway-involving the serine-threonine kinase AKT and the transcription factor XBP1s, which regulates unfolded protein response genes-that was activated in response to IL-15 in human NK cells. IL-15 induced the phosphorylation of AKT, which led to the deubiquitination, increased stability and nuclear accumulation of XBP1s protein. Read More

CSF1R regulates the dendritic cell pool size in adult mice via embryo-derived tissue-resident macrophages.

Nat Commun 2018 12 11;9(1):5279. Epub 2018 Dec 11.

Regeneration in Hematopoiesis and Animal Models in Hematopoiesis, Institute for Immunology, Fetscherstr. 74, 01307, Dresden, Germany.

Regulatory mechanisms controlling the pool size of spleen dendritic cells (DC) remain incompletely understood. DCs are continuously replenished from hematopoietic stem cells, and FLT3-mediated signals cell-intrinsically regulate homeostatic expansion of spleen DCs. Here we show that combining FLT3 and CSF1R-deficiencies results in specific and complete abrogation of spleen DCs in vivo. Read More

GATA2 deficiency and human hematopoietic development modeled using induced pluripotent stem cells.

Blood Adv 2018 Dec;2(23):3553-3565

Hematology Branch, National Heart, Lung, and Blood Institute, National Institutes of Health (NIH), Bethesda, MD.

GATA2 deficiency is an inherited or sporadic genetic disorder characterized by distinct cellular deficiency, bone marrow failure, various infections, lymphedema, pulmonary alveolar proteinosis, and predisposition to myeloid malignancies resulting from heterozygous loss-of-function mutations in the gene. How heterozygous mutations affect human hematopoietic development or cause characteristic cellular deficiency and eventual hypoplastic myelodysplastic syndrome or leukemia is not fully understood. We used induced pluripotent stem cells (iPSCs) to study hematopoietic development in the setting of GATA2 deficiency. Read More

Engrafted parenchymal brain macrophages differ from microglia in transcriptome, chromatin landscape and response to challenge.

Nat Commun 2018 12 6;9(1):5206. Epub 2018 Dec 6.

Department of Immunology, Weizmann Institute of Science, Rehovot, 76100, Israel.

Microglia are yolk sac-derived macrophages residing in the parenchyma of brain and spinal cord, where they interact with neurons and other glial. After different conditioning paradigms and bone marrow (BM) or hematopoietic stem cell (HSC) transplantation, graft-derived cells seed the brain and persistently contribute to the parenchymal brain macrophage compartment. Here we establish that graft-derived macrophages acquire, over time, microglia characteristics, including ramified morphology, longevity, radio-resistance and clonal expansion. Read More

The Role of Salvage Second Autologous Hematopoietic Cell Transplantation in Relapsed Multiple Myeloma.

Biol Blood Marrow Transplant 2018 Dec 8. Epub 2018 Dec 8.

Loyola University Medical Center, Internal Medicine, 2160 S 1(st) Ave, IL, Maywood, Illinois 60153, United States.

Multiple myeloma (MM) is a malignant disorder of plasma cells primarily affecting elderly patients and is the second most commonly diagnosed hematological neoplasm. With the recent influx of effective new agents available including proteasome inhibitors, immunomodulators, targeted monoclonal antibodies, and now chimeric antigen receptor t-cell therapy (CAR-T), the treatment landscape is evolving rapidly. While the role of consolidative autologous stem cell transplantation (ASCT) in first remission is well established, in the relapsed setting following up front ASCT, the role of a second ASCT (SAT) following reinduction is less clear and understudied.

Direct HLA Genetic Comparisons Identify Highly Matched Unrelated Donor/Recipient Pairs with Improved Transplant Outcome.

Biol Blood Marrow Transplant 2018 Dec 8. Epub 2018 Dec 8.

Diagnostic Laboratories and Blood Research Institute, BloodCenter of Wisconsin, part of Versiti, Milwaukee, WI. Electronic address:

HLA matching by allele-level genotyping is largely based on genetic similarity between a few exons which encode the antigen recognition domain (ARD) of the HLA protein. Next-generation sequencing (NGS) can identify HLA genetic polymorphisms in non-ARD encoding exons, introns, and untranslated regions, but the impact of these polymorphisms on hematopoietic cell transplant (HCT) outcomes is unclear. We performed NGS-based sequencing of eleven HLA loci on a well-characterized retrospective cohort of 166 unrelated donor/recipient HCT pairs. Read More

Cell Therapy Laboratory, San Diego Blood Bank, San Diego, California.

Background: Umbilical cord blood (UCB) has become an important source of transplantable CD34 hematopoietic progenitor cells. Cord blood banks (CBBs) can increase their efficiency by minimizing the processing of UCB units with low CD34 content, which have a lower likelihood of transplant utilization. We sought to identify a readily available preprocessing metric that would correlate with CD34 cell counts, without the cost of additional analysis. Read More

Department of Clinical and Experimental Medicine, Division of Cell Biology, Linköping University, Linköping, Sweden.

Mechanical instability of bone implants stimulate osteoclast differentiation and peri-implant bone loss, leading to prosthetic loosening. It is unclear which cells at the periprosthetic interface transduce mechanical signals into a biochemical response, and subsequently facilitate bone loss. We hypothesized that mechanical overloading of hematopoietic bone marrow progenitor cells, which are located near to the inserted bone implants, stimulates the release of osteoclast-inducing soluble factors.

Pre-clinical Development of a Lentiviral Vector Expressing the Anti-sickling βAS3 Globin for Gene Therapy for Sickle Cell Disease.

Mol Ther Methods Clin Dev 2018 Dec 1;11:167-179. Epub 2018 Nov 1.

Department of Life Sciences, University of Modena and Reggio Emilia, Modena, Italy.

Sickle cell disease (SCD) is caused by a mutation (E6V) in the hemoglobin (Hb) β-chain that induces polymerization of Hb tetramers, red blood cell deformation, ischemia, anemia, and multiple organ damage. Gene therapy is a potential alternative to human leukocyte antigen (HLA)-matched allogeneic hematopoietic stem cell transplantation, available to a minority of patients. We developed a lentiviral vector expressing a β-globin carrying three anti-sickling mutations (T87Q, G16D, and E22A) inhibiting axial and lateral contacts in the HbS polymer, under the control of the β-globin promoter and a reduced version of the β-globin locus-control region.

Cytomegalovirus reactivation triggers the late onset of hyperthyroidism after autologous peripheral blood transplantation.

Leuk Res Rep 2019 22;11:5-7. Epub 2018 Nov 22.

Division of Hematology, Japanese Red Cross Society Wakayama Medical Center, Wakayama, Wakayama, Japan.

Thyroid dysfunction is an important issue in patients receiving autologous and allogenic hematopoietic stem cell transplantation (HSCT). However, the exact mechanisms underlying thyrotoxicosis secondary to HSCT remain unclear. The present case exhibited a reversed imbalance in helper/suppressor T-cell populations and B-cell dysregulation for a long time after transplantation, and the reactivation of cytomegalovirus may have been associated with the development of clinical hyperthyroidism.

Myeloid Cells in Intact Human Cervical Explants Capture HIV and Can Transmit It to CD4 T Cells.

Front Immunol 2018 23;9:2719. Epub 2018 Nov 23.

Program in Cellular and Molecular Medicine, Department of Pediatrics, Harvard Medical School, Boston Children's Hospital, Boston, MA, United States.

The importance of myeloid cells in HIV transmission in the female genital tract is uncertain. Because it is difficult to study the early events in HIV transmission in humans, most of our knowledge is based on animal models of SIV infection in Rhesus macaques and more recently HIV infection in humanized mice. However, these models may not accurately recapitulate transmission in the human genital tract. Read More

The Effect of Single-Dose Intraperitoneal Bevacizumab on Peritoneal Adhesion Formation.

Rev Invest Clin 2018 ;70(6):279-284

Department of General Surgery, Ankara Oncology Training and Research Hospital, Ankara, Turkey.

Background: Intra-abdominal adhesions and their complications following abdominal surgery are serious problems, with an incidence of 67-93%. Prevention of peritoneal adhesion formation may eliminate the need for surgical intervention, decreasing complications, morbidity, and cost. Bevacizumab is a recombinant monoclonal antibody which specifically binds vascular endothelial growth factor, an important cytokine in adhesion formation, and neutralizes its biological activity.

Impact of low-dose irradiation and in vivo T-cell depletion on hematopoietic stem cell transplantation for non-malignant diseases using fludarabine-based reduced-intensity conditioning.

Bone Marrow Transplant 2018 Dec 7. Epub 2018 Dec 7.

Department of Community Pediatrics, Perinatal and Maternal Medicine, Tokyo Medical and Dental University, Tokyo, Japan.

Reduced-intensity conditioning is widely used with hematopoietic stem cell transplantation for non-malignant diseases: however, the optimal conditioning to ensure stable engraftment has not been established. In this study, we retrospectively compared the impact of low-dose (1-6 Gy) irradiation and in vivo T-cell depletion on the clinical outcome of 523 patients with non-malignant disease who underwent a first allogeneic hematopoietic stem cell transplantation using fludarabine-based reduced-intensity conditioning. Use of low-dose irradiation, but not of anti-thymocyte globulin/anti-lymphocyte globulin, showed a beneficial effect on overall survival (adjusted hazard ratio: 0. Read More

Real-life feasibility of salvage allogeneic transplantation in peripheral T-cell lymphomas.

Bone Marrow Transplant 2018 Dec 7. Epub 2018 Dec 7.

Division of Hematology and Bone Marrow Transplant, Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, Italy.

Relapsed/refractory Peripheral T-cell Lymphomas are characterized by a poor prognosis, especially for patients who are not candidates for allogeneic hematopoietic stem-cell transplantation. We conducted a retrospective analysis on 73 consecutive patients affected by relapsed/refractory T-Cell lymphomas who were considered eligible for allogeneic transplant. All patients were referred at our center from 2001 to 2017. Read More
