On Defining T-DNA.

Defining CD4 T cell memory by the epigenetic landscape of CpG DNA methylation.

Memory T cells are primed for rapid responses to Ag; however, the molecular mechanisms responsible for priming remain incompletely defined. CpG methylation in promoters is an epigenetic modification, which regulates gene transcription. Using targeted bisulfite sequencing, we examined methylation of 2100 genes (56,000 CpGs) mapped by deep sequencing of T cell activation in human naive and memory...

Effect of LIGHT Adjuvant on Kinetics of T-Cell Responses Induced by HSV-1 DNA Immunization

Background: Studies on efficacy of various vaccines that prevent or reduce the primary and recurrent HSV-1 infection have demonstrated the importance of cellular immunity for protection against the infection. We previously used DNA vaccination to induce cellular immunity against HSV-1 infection in mice. Objective: The aim of our study was to evaluate the effect of LIGHT, a member of TNF super f...

Defining the pathogenicity of DNA sequence variation.

Mendelian Disorders For many cardiac or vascular conditions in which the initial presentation may be fatal, a strong genotype–phenotype correlation is of fundamental importance if genetic diagnosis or prognostication is ever to be useful. Even in classic monogenic disorders, in which large effect sizes are observed, genetic prediction is often confounded by reduced penetrance, wide variation in...

Defining the Etruscans: Language and DNA

انتقال T-DNA وایجاد گیاه تراریخت داتوره (Datura metel L.)

در این تحقیق، شرایط ایجاد گیاه تراریخت از Datura metel L با استفاده از A. tumefaciens حامل پلاسمید pZM1047 شامل ژنهای NPTII، و بتا گلوکورونیداز (GUS) بهینه گردید. از سوسپانسیون باکتری جهت انجام co-culture با قطعات برگ استفاده شد و سپس قطعات گیاه به محیط باززایی MS حاوی ١ میلی گرم در لیتر هورمون BAP، 700 میلی گرم در لیتر سفازولین ، 25 میلی گرم در لیتر کانامایسین منتقل گردیدند. بعد از٢٠-١٥ روز ...
