The conformation of peptides when bound to different HLA class II molecules is of interest in the study of specificity and function of responding T cells. Here, we report the investigation of the HLA-DR binding profiles of an immunodominant and HLA-promiscuous mycobacterial peptide, p38G. Its binding affinities were found to be high for DR1, moderate for DR2, DR7 and DR8, low for DR4, DR5, DR6 ...
In cells latently infected with EBV, the switch from latency to productive infection is linked to the expression of two EBV transcription factors called EB1 (or Z) and R. EB1 is an upstream element factor which has partial homology to the AP1/ATF family, whereas R is an enhancer factor. In the R-responsive enhancer of the replication origin only active during the EBV lytic cycle (ORIIyt), R-res...
To evaluate the hypothesis that adding dexmedetomidine to ropivacaine prolongs axillary brachial plexus block. Forty-five patients of ASA I~II and aged 25-60 yr who were scheduled for elective forearm and hand surgery were randomly divided into 3 equal groups and received 40 ml of 0.33% ropivacaine + 1 ml dexmedetomidine (50 μg) (Group DR1), 40 ml of 0.33% ropivacaine + 1 ml dexmedetomidine (10...
Copolymer 1 (Cop 1, poly (Y, E, A, K)) is a random synthetic amino acid copolymer effective in the treatment of relapsing forms of multiple sclerosis (MS). Cop 1 binds promiscuously, with high affinity and in a peptide-specific manner to purified MS-associated HLA-DR2 (DRB1*1501) and rheumatoid arthritis-associated HLA-DR1 (DRB1*0101) or HLA-DR4 (DRB1*0401) molecules. In the present work at lea...
BACKGROUND The Mycobacterium tuberculosis PhoP/PhoR two-component signal transduction system controls the expression of about 2% of the genome and plays a major role in pathogenicity. However, its regulon has not been well characterized. METHODOLOGY/PRINCIPAL FINDINGS The binding site of PhoP transcription regulator was identified in the upstream regions of msl3, pks2, lipF and fadD21 genes, ...
We consider the operator − d 2 dr2 −V in L2(R+) with Dirichlet boundary condition at the origin. For the moments of its negative eigenvalues we prove the bound tr „
C4 allotyping 13 homozygous C2-deficient individuals demonstrated 23 of 25 haplotypes to be of the relatively rare type C4A4 B2. This is of the same magnitude as the association of C2Q0 with HLA-DW2/DR2.
Background. Recombinant T-cell receptor ligand 1000 (RTL1000) is a single-chain protein construct containing the outer two domains of HLA-DR2 linked to myelin-oligodendrocyte-glycoprotein- (MOG-) 35-55 peptide. Analogues of RTL1000 induce T-cell tolerance, reverse clinical and histological disease, and promote repair in experimental autoimmune encephalomyelitis (EAE) in DR2 transgenic, C57BL/6,...
