Spin correlation and dynamics of excitons in Cd1−MnTe, Cd1−MnSe and Cd1−CoSe
Journal of Crystal Growth, 1992Abstract By time resolved and optical spin orientation spectroscopies of band-edge luminescences, an exchange interaction of excitons with magnetic ions was studied in semimagnetic semiconductors. The exchange interaction gives rise to a marked increase of the exciton luminescence intensity in magnetic fields as well as a dynamical formation process ...

CD1 and CD1-restricted T cells in infections with intracellular bacteria
Trends in Microbiology, 2000Glycolipid-specific, CD1a-, b- and c-dependent cytotoxic T cells have recently been shown to be involved in the host response against tuberculosis. These CD1 molecules 'sample' mycobacterial glycolipids from different intracellular sites in the infected cell. Additionally, upon microbial encounter, CD1d-dependent natural killer T cells promptly produce

AbstractHerein, we report the DNA sequence of two human CD1 genes, R2 and R3, distinct from those encoding the CD1a, ‐b and ‐c antigens. Both genes appear to have an exon/intron structure analogous to the previously analyzed CD1 genes and to be functional on the basis of their sequence.

CD1 were the first human differentiation antigens to be identified by monoclonal antibodies. In this review, we summarize some key results from the molecular study of CD1, with particular reference to their relationship to MHC antigens, and to the existence of two distinct groups of CD1 molecules.

The CD1 family of glycosylated cell surface receptors binds and presents lipid antigens for T cell recognition and activation. Crystal structures of CD1-lipid complexes reveal differences in the mode of presentation of lipids by CD1 group 1 (CDla, CDlb, and CDlc) and group 2 isoforms (CDld).

Photomagnetoresistance Cd1−xMnxTe
Physica B+C, 1983Photoconductivity and photomagnetoresistance (PMR) measurements on Cd1−xMnxTe single crystals for x = 0.05, 0.30 and 0.50 have been carried out in the temperature range 4.2–200 K in magnetic fields up to 10 T. PMR is very large and changes from positive to negative with increasing x.

Spin filtering through Cd1−yMgyTe/Cd1−xMnxTe heterostructure
Physica E: Low-dimensional Systems and Nanostructures, 2008Abstract The spin filtering through Cd 1− y Mg y Te/Cd 1− x Mn x Te heterostructure, both with zero and with positive zero-field conduction band offset, is investigated theoretically. The magnetic field dependence of the transmission coefficients, current densities, and spin polarizations for considered systems have been studied.

Low-temperature refractive indices of Cd1−xMnxTe and Cd1−yMgyTe
Journal of Applied Physics, 1997The refractive indices of Cd1−xMnxTe and Cd1−yMgyTe (0<x<0.28 and 0<y<0.70) were determined by analyzing interference fringes in reflectivity spectra of thin films grown by molecular beam epitaxy. It is shown that their dispersions in the transparent region at 4 K are well described by a Sellmeier relation.

CD1-dependent dendritic cell instruction
Nature Immunology, 2002Both microbial products and T cell factors influence dendritic cell (DC) maturation. However, it is not known which T cells are capable of interacting with DCs at the initiation of adaptive immunity, when foreign antigen-specific T cells are rare. We show here that self-reactive CD1-restricted T cells can promote DC maturation by recognizing CD1 in the

Diverse TCRs Recognize Murine CD1
The Journal of Immunology, 1999Abstract Human and murine T cells that specifically recognize CD1d and produce IL-4 and IFN-γ play a role in immunoregulation and tumor rejection. In the mouse, most CD1d1-reactive T cells described express an invariant Vα14-Jα281 TCR associated with TCR β-chains of limited diversity.
