Cell type specific regulation of immunological synapse dynamics by B7 ligand recognition

open access: yesFrontiers in Immunology, 2016
B7 proteins CD80 (B7-1) and CD86 (B7-2) are expressed on most antigen presenting cells and provide critical costimulatory or inhibitory input to T cells via their T-cell expressed receptors: CD28 and CTLA-4. CD28 is expressed on effector and regulatory T

Microchimerism, dendritic cell progenitors and transplantation tolerance [PDF]

open access: yes, 1995
The recent discovery of multilineage donor leukocyte microchimerism in allograft recipients up to three decades after organ transplantation implies the migration and survival of donor stem cells within the host.

Allelic variation in HLA-B and HLA-C sequences and the evolution of the HLA-B alleles [PDF]

open access: yes, 1989
Several new HLA-B (B8, B51, Bw62)- and HLA-C (Cw6, Cw7)-specific genes were isolated either as genomic cosmid or cDNA clones to study the diversity of HLA antigens.

Immune checkpoint: The novel target for antitumor therapy

open access: yesGenes and Diseases, 2021
Inhibitory checkpoint molecules include programmed cell death-1 (PD-1), programmed cell death ligand-1 (PD-L1), cytotoxic T lymphocyte antigen-4 (CTLA-4), human endogenous retrovirus-H Long terminal repeat-associating 2 (HHLA2), B7 homolog 4 protein (B7 ...

B7 costimulation and intracellular indoleamine-2,3-dioxygenase (IDO) expression in peripheral blood of healthy pregnant and non-pregnant women. [PDF]

open access: yes, 2014
BACKGROUND: B7 costimulatory molecules are expressed on antigen presenting cells (APCs) and are important regulators of T cell activation. We investigated the role of the B7 family of costimulatory molecules in the development of the systemic maternal ...

CTLA-4 and PD-1 ligand gene expression in epithelial thyroid cancers [PDF]

open access: yes, 2018
The dysregulation of PD-1 ligands (PD-L1 and PD-L2) and CTLA-4 ligands (CD80 and CD86) represents a tumor strategy to escape the immune surveillance. Here, the expression of PD-L1, PD-L2, CD80 and CD86 was evaluated at mRNA level in 94 patients affected ...

Genetic and serological heterogeneity of the supertypic HLA-B locus specificities Bw4 and Bw6 [PDF]

open access: yes, 1989
Gene cloning and sequencing of the HLA-B locus split antigens B38 (B16.1) and B39 (B16.2) allowed localization of their subtypic as well as their public specificities HLA-Bw4 or -Bw6 to the c~-helical region of the c~ 1 domain flanked by the amino acid ...

Suppression of Human T-Cell Responses to β-Cells by Activation of B7-H4 Pathway

open access: yesCell Transplantation, 2006
B7-H4, a recently described member of the B7 family of cosignal molecules, is thought to be involved in the regulation of cellular and humoral immune responses through receptors on activated T and B cells. Human islet cells express positive B7-H4 mRNA in
