New approaches to uncover the minimally functional hematopoietic niche using the adipocytic differentiation axis: pharmacological modulation and adrenal niche induction

Hematopoietic Stem and Progenitor Cells (HSPCs) reside in their niche, a structure that regulates the balance of cellular quiescence, self-renewal and commitment towards differentiated cells. This highly plastic niche is formed by several cellular players, ...

Introducing tolerance to foreign and partly foreign proteins by erythrocyte binding and artificial glycosylations

Kym Lorenz Brünggel

Over the last few years, protein drugs have steadily gained importance in the clinic. Compared to small molecule drugs, protein drugs are taken up by antigen presenting cells, which degrade the proteins into peptides that are then presented on major histoc ...

Memory of tolerance and induction of regulatory T cells by erythrocyte-targeted antigens

Jeffrey Alan Hubbell, Xavier Fredy René Quaglia-Thermes, Giacomo Olimpio Diaceri, Stephane Kontos, Alizée Jéléna Grimm

New approaches based on induction of antigen-specific immunological tolerance are being explored for treatment of autoimmunity and prevention of immunity to protein drugs. Antigens associated with apoptotic debris are known to be processed tolerogenically ...

Fe-59-distribution in conditional ferritin-H-deleted mice

Liviu Vanoaica, Stefan Wagner

The objective was to explore how ferritin-H deletion influences Fe-59-distribution and excretion-kinetics in mice. Kinetics of Fe-59-release from organs, whole-body excretion, and distribution-kinetics of intravenously injected Fe-59 trace amounts were com ...

A KRAB/KAP1-miRNA Cascade Regulates Erythropoiesis Through Stage-Specific Control of Mitophagy

Didier Trono, Jiri Vanicek, Sandra Eloise Kjeldsen, Isabelle Barde, Sonia Verp, Adamantia Kapopoulou, Andrea Corsinotti, Benjamin Rauwel, Ray Marcel Marin Florez

During hematopoiesis, lineage- and stage-specific transcription factors work in concert with chromatin modifiers to direct the differentiation of all blood cells. Here, we explored the role of KRAB-containing zinc finger proteins (KRAB-ZFPs) and their cofa ...

Pten loss in the bone marrow leads to G-CSF-mediated HSC mobilization

Irène Baccelli

The phosphatase and tumor suppressor PTEN inhibits the phosphoinositol-3-kinase (PI3K) signaling pathway and plays a key role in cell growth, proliferation, survival, and migration. Pten conditional deletion using MxCre or Scl-CreERT leads to splenomegaly ...

Erythrocyte-binding therapeutics

Jeffrey Alan Hubbell, Stephane Kontos, Karen Dane

Peptides that specifically bind erythrocytes are described. These are provided as peptidic ligands having sequences that specifically bind, or as antibodies or fragments thereof that provide specific binding, to erythrocytes. The peptides may be prepared a ...

The transcriptional landscape of hematopoietic stem cell ontogeny

Olaia Maria Naveiras Torres-Quiroga

Transcriptome analysis of adult hematopoietic stem cells (HSCs) and their progeny has revealed mechanisms of blood differentiation and leukemogenesis, but a similar analysis of HSC development is lacking. Here, we acquired the transcriptomes of developing ...

Enhanced c-Met activity promotes G-CSF-induced mobilization of hematopoietic progenitor cells via ROS signaling

Mechanisms governing stress-induced hematopoietic progenitor cell mobilization are not fully deciphered. We report that during granulocyte colony-stimulating factor-induced mobilization c-Met expression and signaling are up-regulated on immature bone marro ...

Engineering Erythrocyte Affinity for Improved Pharmacokinetics and Immune Tolerogenesis

Stephane Kontos

The clinical success of recombinant protein therapeutics in the treatment of disease is a hallmark of modern medical research, yet there remain numerous unaddressed issues regarding their delivery and immunogenicity. Regardless of in vivo efficacy, the bio ...
