    The Emerging Link Between the Complement Cascade and Purinergic Signaling in Stress Hematopoiesis.
    Front Immunol 2018 5;9:1295. Epub 2018 Jun 5.
    Department of Hematology Warsaw Medical University, Warsaw, Poland.
    Innate immunity plays an important role in orchestrating the immune response, and the complement cascade (ComC) is a major component of this ancient defense system, which is activated by the classical-, alternative-, or mannan-binding lectin (MBL) pathways. However, the MBL-dependent ComC-activation pathway has been somewhat underappreciated for many years; recent evidence indicates that it plays a crucial role in regulating the trafficking of hematopoietic stem/progenitor cells (HSPCs) by promoting their egress from bone marrow (BM) into peripheral blood (PB). This process is initiated by the release of danger-associated molecular patterns (DAMPs) from BM cells, including the most abundant member of this family, adenosine triphosphate (ATP). Read More

    Anti-Inflammatory Biologics and Anti-Tumoral Immune Therapies-Associated Colitis: A Focused Review of Literature.
    Gastroenterology Res 2018 Jun 31;11(3):174-188. Epub 2018 May 31.
    Department of Pathology, Immunology and Laboratory Medicine, College of Medicine, University of Florida, Gainesville, FL, USA.
    An increasing number of drugs including monoclonal antibodies and small molecules, either anti-inflammatory or immunity-enhancing, have been developed to treat human diseases and the number of medications in these classes is likely to expand in the future. The two most commonly used categories of such therapies are the anti-inflammatory group (anti- tumor necrosis factor (TNF) α, anti-interleukins/interleukin receptors, and anti-integrin bodies) and the anti-tumoral agents (immune checkpoint inhibitors, anti-CD20, and anti-endothelial growth factor). Although the anti-inflammatory biologics have brought about a revolutionary effect in the management of a variety of autoimmune disorders including rheumatologic diseases, inflammatory bowel disease, and inflammatory dermatological diseases, their ability to induce colitis in patients without a prior history of colitis or exacerbate quiescent colitis has been increasingly and unexpectedly recognized.

    Front Immunol 2018 25;9:1138. Epub 2018 May 25.
    Department of Medicine 1, University Hospital Erlangen, University of Erlangen-Nuremberg, Kussmaul Campus for Medical Research, Erlangen, Germany.
    Intestinal graft-versus-host disease (GvHD) is a life-threatening, inflammatory donor T cell-mediated complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT). In the light of the reported efficacy of interleukin-23 (IL-23)-blockade to mitigate syngeneic intestinal inflammation in inflammatory bowel disease patients, targeting IL-23 and thereby interleukin-17a (IL-17a) producing T helper (Th17) cells as the T cell subset assumed to be mostly regulated by IL-23, has emerged as a putatively general concept to harness immune-mediated mucosal inflammation irrespective of the underlying trigger. However, the role of Th17 cells during allo-response driven colitis remains ambiguous due to a series of studies with inconclusive results. Read More

    Allograft and patient survival after sequential HSCT and kidney transplantation from the same donor- a multicenter analysis.
    Am J Transplant 2018 Jun 13. Epub 2018 Jun 13.
    Department of Internal Medicine III, Division of Nephrology and Dialysis, Medical University of Vienna, Vienna, Austria.
    Tolerance induction through simultaneous hematopoietic stem cell- and renal transplantation has shown promising results, but it is hampered by the toxicity of preconditioning therapies and graft-versus-host disease. Moreover, renal function has never been compared to conventionally transplanted patients, thus, whether donor-specific tolerance results in improved outcomes remains unanswered. We collected follow-up data of published cases of renal transplantations after hematopoietic stem cell transplantation from the same donor and compared patient- and transplant kidney survival- as well as function with caliper-matched living-donor renal transplantations from the Austrian dialysis and transplant registry.

    The function of medullary thymic epithelial cells (mTECs) is associated with thymocyte adhesion, which is crucial for the negative selection of autoreactive thymocytes in the thymus. This process represents the root of central tolerance of self-components and prevents the onset of autoimmune diseases. Since thymic epithelia correspond to an important target of donor T cells during the onset of chronic graft-vs-host-disease, mTEC-thymocyte adhesion may have implications for alloimmunity. Read More

    Background: Reduced-intensity conditioning (RIC) regimens with low tolerable toxicities have been used for allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, the relapse rate by this treatment is high. Treatment of CD19 B-cell relapsed/refractory acute lymphoblastic leukemia (r/r ALL) with allogeneic chimeric antigen receptor-modified T (CAR-T) cells is safe and effective. Read More

    The optimal treatment strategy for gastrointestinal graft-versus-host disease (GI-GVHD) after allogeneic hematopoietic cell transplantation remains to be established. We retrospectively analyzed 68 cases of GI-GVHD at our institution between 2007 and 2017. The survival outcomes were significantly inferior in patients who did not respond to the first-line treatment (1-year overall survival 27. Read More
