The mammalian major histocompatibility complex (MHC) plays important roles in pathogen recognition and disease resistance. In the present study, the coding sequence and the 5'- and 3'-untranslated regions of MHC class II DR alpha chain (the DRA gene) from rare gayal and gaytle were cloned and analyzed to dissect structural and functional variations. The nucleotide and amino acid sequences for t...

PROBLEM The regulatory mechanisms governing differential expression of classical major histocompatibility complex (MHC) class I (MHC-Ia) and non-classical MHC class I (MHC-Ib) genes are poorly understood. METHOD OF STUDY Quantitative reverse transcription- polymerase chain reaction (PCR) was used to compare the abundance of MHC-I transcripts and related transcription factors in peripheral blo...

We fabricated a new class of supported membranes based on monolayers of artificial bola (transmembrane) lipids. The lipids used in this study are symmetric bola lipids with two phosphocholine head groups, which resemble natural archaea lipids. To prevent bending of the hydrocarbon chains, stiff triple bonds are inserted in the middle of the hydrocarbon cores. The formation of homogeneous "monol...

BACKGROUND The purpose of this study was twofold: to evaluate the quantitative stability of a SPECT/CT gamma camera over time and to determine if daily flood acquisitions can reliably serve as calibration factors for quantitative SPECT. Using a cylindrical water phantom filled with measured amounts of (99m)Tc, factors were calculated to convert counts/cc to activity/cps. Measurements were made ...

Proton ENDOR spectroscopy was used to monitor local conformational changes in bacterial reaction centers (RC) associated with the electron-transfer reaction DQB --> D+*QB-* using mutant RCs capable of photoreducing QB at cryogenic temperatures. The charge separated state D+*QB-* was studied in mutant RCs formed by either (i) illuminating at low temperature (77 K) a sample frozen in the dark (gr...

BACKGROUND Although inflammation in Crohn's disease is believed to be mediated by activated T cells, genotyping of all MHC class II alleles in white people with this disease has not been reported. AIMS To perform a detailed molecular analysis of HLA DPB, DQB, and DRB genes in white patients with Crohn's disease and controls in order to determine if the inheritance of any class II genes confer...

In previous reports of studies of Scandinavian sarcoidosis patients, we have described a strong association between lung-restricted expansions of T cells expressing T-cell receptor (TCR) AV2S3 and the human leukocyte antigen (HLA)-DRB1*0301 (DR17) and -DRB3*0101 alleles, suggesting the presence of a specific antigen in sarcoidosis. In the present study, the degree of lung-accumulated TCR AV2S3(...

OBJECTIVE To find an association between human leukocyte antigen (HLA) class II DRB1, DRB3, DRB4, and DRB5 alleles frequencies in a sample of Iraqi patients with Guillain-Barre syndrome (GBS) and compare with a healthy control group. METHODS We performed a cross-sectional study consisting of 30 Iraqi Arab patients with GBS attending the Neurological Department in the Neuroscience Hospital, Ba...
