Immunodominance hierarchies are a substantial, but poorly understood, characteristic of CD8(+) T cell-mediated immunity. Factors influencing the differential responses to the influenza A virus nucleoprotein (NP(366-374)) and acid polymerase (PA(224-233)) peptides presented by H2D(b) have been analyzed by disabling (N5--> Q substitution) these peptides in their native configuration, then express...

To elucidate effects of electrostatic interactions resulting from surface charges on structures and phase stability of cubic phases of lipid membranes, membranes of 1-monoolein (MO) and dioleoylphosphatidic acid (DOPA) (DOPA/MO membrane) mixtures have been investigated by small-angle x-ray scattering method. As increasing DOPA concentration in the DOPA/MO membrane at 30 wt% lipid concentration,...

The primary structure of human renin, recently established from the complementary DNA sequence of its messenger RNA, shows a strong homology to other aspartyl proteases. This homology has permitted the construction of a model of the three-dimensional structure of renin based on the crystallographically determined structures of three aspartyl proteases: penicillopepsin, endothiapepsin, and rhizo...

MicroRNAs (miRs) play a key role in the control of gene expression in a wide array of tissue systems, where their functions include the regulation of self-renewal, cellular differentiation, proliferation and apoptosis. However, the function and mechanisms of individual miRs in regulating spermatogonial stem cell (SSC) homeostasis remain unclear. In the present study, we report for the first tim...

The underlying malignancy of mucinous cystic neoplasms (MCNs) of the pancreas most commonly results in patients undergoing surgery. The tumorigenesis of MCNs remains elusive and few studies have investigated the role of specific micro (mi)RNAs in MCNs. The present study focused on the expression of miRNA‑224 and its putative target gene Jagged1 (Jag1) to examine its role in tumorigenesis and it...
