دراین مطالعه از سفالومتری lateral مربوط به " 38 " کودک دارای مال اکلوژنclass iii, class ii , class i که قبلا " تحت درمان قرار نگرفته اند، استفاده شده است . دربررسی سفالومتری و تجزیه و تحلیل نتایج آماری، اطلاعات زیر بدست آمد)1 : ارتباط بین زوایای saddle و sna معکوس بوده، اما تنها درگروه class iii ارتباط معنی دار و قوی است .)2 ارتباط بین زوایای saddle و snbنیز معکوس بوده، درگروه class ii و class ...
Three MHC class II-derived synthetic peptides (I-A beta (g7)1-16, I-A beta (g7)52-77 and I-A alpha (g7)63-82YC) were analyzed for their ability to bind to syngeneic and allogeneic MHC class II molecules using a whole cell, competitive peptide binding assay. These studies demonstrated that the A beta (g7)1-16 peptide was able to specifically bind to syngeneic as well as to four allogeneic MHC cl...
The small GTPase RAB4 regulates endocytic recycling, a process that contributes to Major Histocompatibility Complex (MHC)-mediated antigen presentation by specialized antigen presenting cells (APC) of the immune system. The gene encoding the RAB4B isoform of RAB4 was singled out by two complementary genome-wide screens. One of these consisted of a computer scan to identify genes containing char...
PURPOSE To examine the postnatal development of major histocompatibility complex (MHC) class II-positive dendritic cells (DC) in the iris of the normal rat eye. METHODS Single- and double-color immunomorphologic studies were performed on whole mounts prepared from rat iris taken at selected postnatal ages (2 to 3 days to 78 weeks). Immunopositive cells were enumerated, using a quantitative li...
The ability of superantigens (SAGs) to trigger various cellular events via major histocompatibility complex (MHC) class II molecules is largely mediated by their mode of interaction. Having two MHC class II binding sites, staphylococcal enterotoxin A (SEA) is able to dimerize MHC class II molecules on the cell surface and consequently induces cytokine gene expression in human monocytes. In cont...
Previous data from many groups show that both class I and class II-restricted T cells recognize short synthetic peptides in the context of their respective MHC molecules (9-18), all of the peptides described to date are restricted to only a single class of MHC molecules; however, structural homology between the class I and II MHC molecules and the use of similar TCRs by class I and II-restricte...
Major histocompatibility complex (MHC) class II antigens are discordantly expressed on hematopoietic progenitor cells. Their expression is linked to differential responsiveness of the cells to growth factors and inhibitors. We examined the expression of different MHC class II antigens in a panel of human myelomonocytic cell lines representing different stages of differentiation, by cytofluorogr...
