Deficient regulatory B cells in human chronic graft-versus-host disease.

Oncoimmunology

de Masson A, Socié G, Bagot M, Bensussan A, Bouaziz JD.
PMID: 26140245
Oncoimmunology. 2015 Apr 01;4(7):e1016707. doi: 10.1080/2162402X.2015.1016707. eCollection 2015 Jul.

Human chronic graft-versus-host disease (cGVHD) is a frequent and disabling complication of allogeneic hematopoietic stem cell transplantation. Regulatory B cells (Bregs) are IL-10-producing B cells that are able to inhibit the innate and adaptive immune responses. We have recently...

ACS Med Chem Lett. 2017 Feb 14;8(3):338-343. doi: 10.1021/acsmedchemlett.6b00519. eCollection 2017 Mar 09.

Misdirected catalytic activity of histone methyltransferase Dot1L is believed to be causative for a subset of highly aggressive acute leukemias. Targeting the catalytic domain of Dot1L represents a potential therapeutic approach for these leukemias. In the context of a...

Topological scenario for stripe formation in manganese oxides.

Physical review letters

Hotta T, Takada Y, Koizumi H, Dagotto E.
PMID: 11018914
Phys Rev Lett. 2000 Mar 13;84(11):2477-80. doi: 10.1103/PhysRevLett.84.2477.

The spin-charge-orbital complex structures of manganites are studied using topological concepts. The key quantity is the "winding number" w associated with the Berry-phase connection of an e(g) electron parallel transported through Jahn-Teller centers, along zigzag one-dimensional paths in an...

Giant cluster coexistence in doped manganites and other compounds.

Physical review letters

Moreo A, Mayr M, Feiguin A, Yunoki S, Dagotto E.
PMID: 10990996
Phys Rev Lett. 2000 Jun 12;84(24):5568-71. doi: 10.1103/PhysRevLett.84.5568.

Computational studies of models for manganese oxides show the generation of large coexisting metallic and insulating clusters with equal electronic density, in agreement with the recently discovered micrometer-sized inhomogeneities in manganites. The clusters are induced by disorder on exchange...

Prediction of orbital ordering in single-layered ruthenates.

Physical review letters

Hotta T, Dagotto E.
PMID: 11800983
Phys Rev Lett. 2002 Jan 07;88(1):017201. doi: 10.1103/PhysRevLett.88.017201. Epub 2001 Dec 17.

The key role of the orbital degree of freedom to understanding the magnetic properties of layered ruthenates is discussed based on the 3-orbital Hubbard model coupled to lattice distortions, using numerical and mean-field techniques. In the G-type antiferromagnetic phase...

Phase diagram of a model for diluted magnetic semiconductors beyond mean-field approximations.

Physical review letters

Alvarez G, Mayr M, Dagotto E.
PMID: 12513238
Phys Rev Lett. 2002 Dec 30;89(27):277202. doi: 10.1103/PhysRevLett.89.277202. Epub 2002 Dec 19.

A lattice spin-fermion model for diluted magnetic semiconductors (DMS) is investigated numerically, improving on previously used mean-field approximations. Curie temperatures are obtained varying the Mn spin x and hole n densities, and the impurity-hole exchange J in units of...

Ferroelectricity in the magnetic E-phase of orthorhombic perovskites.

Physical review letters

Sergienko IA, Sen C, Dagotto E.
PMID: 17155837
Phys Rev Lett. 2006 Dec 01;97(22):227204. doi: 10.1103/PhysRevLett.97.227204. Epub 2006 Nov 30.

We show that the symmetry of the spin zigzag chain E phase of the orthorhombic perovskite manganites and nickelates allows for the existence of a finite ferroelectric polarization. The proposed microscopic mechanism is independent of spin-orbit coupling. We predict...

Transport properties of strongly correlated electrons in quantum dots studied with a simple circuit model.

Physical review letters

Martins GB, Büsser CA, Al-Hassanieh KA, Anda EV, Moreo A, Dagotto E.
PMID: 16606028
Phys Rev Lett. 2006 Feb 17;96(6):066802. doi: 10.1103/PhysRevLett.96.066802. Epub 2006 Feb 13.

Numerical calculations are shown to reproduce the main results of recent experiments involving nonlocal spin control in quantum dots [Craig, Science 304, 565 (2004).]. In particular, the experimentally reported zero-bias-peak splitting is clearly observed in our studies. To understand...

Exchange bias driven by the Dzyaloshinskii-Moriya interaction and ferroelectric polarization at G-type antiferromagnetic perovskite interfaces.

Physical review letters

Dong S, Yamauchi K, Yunoki S, Yu R, Liang S, Moreo A, Liu JM, Picozzi S, Dagotto E.
PMID: 19792455
Phys Rev Lett. 2009 Sep 18;103(12):127201. doi: 10.1103/PhysRevLett.103.127201. Epub 2009 Sep 14.

Exchange bias is usually rationalized invoking spin pinning effects caused by uncompensated antiferromagnetic interfaces. However, for compensated antiferromagnets other extrinsic factors, such as interface roughness or spin canting, have to be considered to produce a small uncompensation. As an...

Dual nature of improper ferroelectricity in a magnetoelectric multiferroic.

Physical review letters

Picozzi S, Yamauchi K, Sanyal B, Sergienko IA, Dagotto E.
PMID: 18233318
Phys Rev Lett. 2007 Nov 30;99(22):227201. doi: 10.1103/PhysRevLett.99.227201. Epub 2007 Nov 26.

Using first-principles calculations, we study the microscopic origin of ferroelectricity (FE) induced by magnetic order in the orthorhombic HoMnO3. We obtain the largest ferroelectric polarization observed in the whole class of improper magnetic ferroelectrics to date. We find that...
