Recently, haplotype-based association studies have become popular for detecting disease-related or drug-response-associated genes. In these studies, it has been gradually recognized that a haplotype block structure is important. A rational and automatic method for identifying the haplotype block structure from SNP data has been desirable. We have developed a new method by using an ancestor-deri...
The recognition of virus infected or malignantly transformed cells by cytotoxic T lymphocytes critically depends on the transporter associated with antigen processing (TAP), which delivers proteasomal degradation products into the endoplasmic reticulum lumen for subsequent loading of major histocompatibility complex class I molecules. Here we have identified a single cysteinyl residue in the TA...
Sequence analyses of the transporter associated with antigen processing (TAP) in tumor cell lines with deficient MHC class I surface expression identified a bp deletion at position 1489 near the ATP-binding domain of Tap1, causing a frameshift in one melanoma cell line. The impaired TAP1 protein expression was associated with deficient TAP2 protein expression, peptide binding, translocation, an...
چکیده: پیشینه تحقیق : اسکیزوفرنی یک اختلال ناتوان کننده عصبی مزمن و پیچیده است که احتمالاً به وسیله¬ی فاکتورهای ژنتیکی و غیره ژنتیکی تحت تأثیر قرار می¬گیرد. میزان شیوع این بیماری در جوامع مختلف بین 7/-1 درصد است و از اهمیت زیادی برخوردار است به همین دلیل مطالعات مختلفی در این زمینه صورت گرفته است . این بیماری نشانگان متنوع و در عین حال تخریب کننده¬ای دارد که تفکر، ادراک، هیجان، حرکت و رفتار فرد...
Specific CD8(+) CTL recognition of melanoma requires expression of MHC class I molecules as well as melanoma-associated peptide epitopes. Human melanoma cells may escape immune recognition by a variety of means, including global or allelic down-regulation of MHC class I molecules. Stable MHC class I cell surface expression requires delivery of cytosolic peptides into the endoplasmic reticulum b...
The transporter associated with antigen processing (TAP) delivers peptides to the lumen of the endoplasmic reticulum in an adenosine triphosphate (ATP) dependent fashion for presentation by major histocompatibility complex class I molecules. We show that the mouse TAP translocator (H-2b haplotype) selects peptides based on a minimal size of nine residues, and on the presence of a hydrophobic CO...
