LMIR5 extracellular domain activates myeloid cells through Toll-like receptor 4.
LMIR5/CD300b is an activating immunoglobulin-like receptor whose extracellular domain (LMIR5-Fc) is constitutively released from immune cells. The release of LMIR5-Fc is augmented upon stimulation with TLR agonists. LMIR5-Fc is reported to possess inflammatory activity and amplify LPS-induced lethal...
pH dependence of antibody: hapten association.
Monoclonal antibody NC6.8 is specific for the superpotent sweetener, N-(p-cyanophenyl)-N'-(diphenylmethyl)-guanidiniumacetic++ + acid. The three-dimensional structure of the complex shows the close proximity of complementary charged residues on the antibody and groups of the hapten. As a result, asso...
The murine p75 TNF receptor promoter region: DNA sequence and characterization of a cis-acting silencer.
The promoter region of the murine p75 TNF receptor (TNF-R) was isolated from a mouse genomic DNA cosmid library. The promoter region is devoid of TATA box and has the characteristics of a house keeping gene since it contains multiple SP1 binding sites. Its mRNA has different initiation sites in diff...
Modulation of class I major histocompatibility complex antigen cell-surface stability by transmembrane domain length variation.
I proteins is conferred to a large extent by their transmembrane domains (TMs) which exhibit allelic, inter-locus and inter-species variation in both amino acid composition and length. Here, the consequences of TM length variation on trafficking and cell-surface stability were examined using the hum...
Isolation and N-terminal sequence determination of a novel gamma/delta T cell surface antigen.
We use digestion with the proteolytic enzyme bromelain to selectively release the MAC319 antigen as a soluble fragment, for further characterisation. A cytofluorometric inhibition assay was developed to follow the purification of this fragment, as the conformation sensitivity of the MAC319 epitope p...
Blood clearance in the rat of a recombinant mouse monoclonal antibody lacking the N-linked oligosaccharide side chains of the CH2 domains.
The serum half-lives of a wild-type recombinant mouse monoclonal antibody of the IgG2b isotype and a mutant antibody differing from the wild-type antibody by a single amino acid substitution introduced into the CH2 domain, the replacement of Asn 297 by Ala to delete the conserved sit...
A murine monoclonal anti-metallothionein autoantibody recognizes a chemically synthesized amino-terminal heptapeptide common to various anim...
These results demonstrate that the MT 189-14-7 autoantibody recognizes the epitope located within the amino-terminal heptapeptide common to various MTs....
Crystal structure of deglycosylated human IgG4-Fc.
We reported the crystal structure of glycosylated IgG4-Fc, revealing structural features that could explain the anti-inflammatory biological properties of IgG4 compared with IgG1. We now report the crystal structure of enzymatically deglycosylated IgG4-Fc, derived from human serum, at 2.7Å resolutio...
Altered DNA methylation profile in Norwegian patients with Autoimmune Addison's Disease.
We identified multiple hypomethylated gene promoter regions in patients with isolated AAD using DNA isolated from CD4+ T cells. The identified differentially methylated regions were distributed evenly across the 10.5-kb-promoter regions covered by the array, and a substantial number localized to pro...
Serum amyloid A induces mitogenic signals in regulatory T cells via monocyte activation.
We provide evidence that IL-1β and IL-6 are directly involved in the SAA-mediated proliferation of Treg. By engaging its several cognate receptors, SAA induces IL-1β and IL-6 secretion by monocytes and drives them toward an HLA-DR(hi) HVEM(lo) phenotype resembling immature dendritic cells, which hav...
