Neutrophils in lupus nephritis.

Curr Opin Rheumatol 2018 Dec 11. Epub 2018 Dec 11.

Center for Excellence in Vascular Biology, Department of Pathology, Brigham and Women's Hospital & Harvard Medical School, Boston, USA.

Purpose Of Review: Systemic lupus erythematosus (SLE) is a multiorgan autoimmune disease characterized by IgG-autoantibodies to nuclear antigens that can deposit in the kidney and trigger lupus nephritis. Neutrophils accumulate in the kidneys of patients with proliferative LUPUS NEPHRITIS and neutrophil products and a subset of granulocytes, called low-density granulocytes (LDG) may contribute to lupus nephritis pathogenesis. Here, we will discuss recent studies implicating neutrophils in the pathogenesis of human SLE nephritis and then examine studies that provide mechanistic insights into how these cells are recruited to the glomerulus following immune complex deposition and how their products may promote lupus nephritis.

Connexin-43 Gap Junctions Are Responsible for the Hypothalamic Tanycyte-Coupled Network.

Front Cell Neurosci 2018 26;12:406. Epub 2018 Nov 26.

Department of Cellular Biology, Faculty of Biological Sciences, University of Concepcion Concepcion, Chile.

Tanycytes are hypothalamic radial glia-like cells that form the basal wall of the third ventricle (3V) where they sense glucose and modulate neighboring neuronal activity to control feeding behavior. This role requires the coupling of hypothalamic cells since transient decreased hypothalamic Cx43 expression inhibits the increase of brain glucose-induced insulin secretion. Tanycytes have been postulated as possible hypothalamic neuronal precursors due to their privileged position in the hypothalamus that allows them to detect mitogenic signals and because they share the markers and characteristics of neuronal precursors located in other neurogenic niches, including the formation of coupled networks through connexins.

Thy-1 (CD90) Signaling Preferentially Promotes RORγt Expression and a Th17 Response.

Front Cell Dev Biol 2018 23;6:158. Epub 2018 Nov 23.

Department of Microbiology and Immunology, Dalhousie University, Halifax, NS, Canada.

Thy-1 (CD90) is a glycosylphosphatidylinositol-anchored protein (GPI-AP) with signaling properties that is abundant on mouse T cells. Upon antibody-mediated crosslinking, Thy-1 provides a T cell receptor (TcR)-like signal that is sufficient to drive CD4 T cell proliferation and differentiation into effector cells when costimulatory signals are provided by syngeneic lipopolysaccharide-matured bone marrow-derived dendritic cells. In this study, we investigated the impact of Thy-1 signaling on the production of the T helper (Th) cell subset-associated cytokines, interferon (IFN) γ, interleukin (IL)-4 and IL-17A, as well as the polarization of highly purified resting CD4 T cells into Th1, Th2, and Th17 cells.

All trans-retinoic acid (ATRA) is used in the treatment of acute promyelocytic leukemia (APL) and it is a promising agent also in solid tumors. The pharmacological activity of ATRA is mediated by the ligand-activated RAR and RXR transcription factors. In the present study, we define the basal and ATRA dependent RARα interactome in a RARα-overexpressing breast cancer cellular model, identifying 28 nuclear proteins. Read More

Ablation of miR-146b in mice causes hematopoietic malignancy.

Blood Adv 2018 Dec;2(23):3483-3491

Department of Systems BioMedicine, Graduate School of Medical and Dental Sciences.

Excessive and constitutive activation of nuclear factor-κB (NF-κB) leads to abnormal cell proliferation and differentiation, leading to the development of malignant tumors, including lymphoma. MicroRNA 146a (miR-146a) and miR-146b, both of which carry an identical seed sequence, have been shown to contribute to inflammatory diseases and tumors by suppressing the expression of key molecules required for NF-κB activation. However, the functional and physiological differences between miR-146a and miR-146b in disease onset have not been fully elucidated. Read More

Profiling proliferative cells and their progeny in damaged murine hearts.

Proc Natl Acad Sci U S A 2018 Dec 7. Epub 2018 Dec 7.

Hubrecht Institute, Royal Netherlands Academy of Arts and Sciences and University Medical Centre Utrecht, 3584 CT Utrecht, The Netherlands;

The significance of cardiac stem cell (CSC) populations for cardiac regeneration remains disputed. Here, we apply the most direct definition of stem cell function (the ability to replace lost tissue through cell division) to interrogate the existence of CSCs. By single-cell mRNA sequencing and genetic lineage tracing using two Ki67 knockin mouse models, we map all proliferating cells and their progeny in homoeostatic and regenerating murine hearts.
