PURPOSE Immunotherapy using vaccines or adoptively transferred tumor-infiltrating lymphocytes (TIL) is limited by T-cell functional inactivation within the solid tumor microenvironment. The purpose of this study was to determine whether a similar tumor-induced inhibition occurred with genetically modified cytotoxic T cells expressing chimeric antigen receptors (CAR) targeting tumor-associated a...
PURPOSE Tumor-infiltrating lymphocytes (TILs) become hypofunctional, although the mechanisms are not clear. Our goal was to generate a model of human tumor-induced TIL hypofunction to study mechanisms and to test anti-human therapeutics. EXPERIMENTAL DESIGN We transduced human T cells with a published, optimized T-cell receptor (TCR) that is directed to a peptide within the cancer testis anti...
The factors and steps controlling postinfection CD8+ T cell terminal effector versus memory differentiation are incompletely understood. Whereas we found that naive TCF7 (alias "Tcf-1") expression is FOXO1 independent, early postinfection we report bimodal, FOXO1-dependent expression of the memory-essential transcription factor TCF7 in pathogen-specific CD8+ T cells. We determined the early pos...
Abstract: Background: Streptokinase has been widely prescribed as a fibrinolytic agent for myocardial infarction. Simple structural characteristics of this protein have provided techniques for production of different recombinant types of this protein. The present study was designed to prepare equisimilisH46A subtype of streptokinase in our country. Materials and methods: Having extracted the...
بیان موقت ژنهای بیگانه در بافتهای گیاهی برای آنالیز عملکرد ژن در زمان کوتاه روش کارآمدی میباشد. این روش سریع، انعطاف پذیر، ساده و در بافتهای تمایز یافته قابل اجرا است. پیشبر 2a11 از پیشبرهای ویژه بافت میوه گیاه گوجهفرنگی است که باعث بیان بالای ژن 2a11 در میوه میشود. هدف از این تحقیق همسانهسازی پیشبر 2a11 و بررسی بیان آن است. پس از استخراج dna ژنومی از گیاه گوجهفرنگی، پیشبر 2a11 با استفا...
BACKGROUND The parasites Toxoplasma gondii (T. gondii) and Neospora caninum (N. caninum) are globally distributed; they infect warm-blooded animals, including many avian species. The aim of this study was to evaluate the presence of these parasites in ostriches from central China. In total, 402 ostrich (Struthio camelus) samples (293 hearts, 77 brains, and 32 serum) from slaughterhouses of the ...
Abstract Objective: Interferon-γ (IFN-γ) is a key cytokine regulating the development of atherosclerosis, but little known regarding phenotype and regulation T cells producing IFN-γ in plaques. Methods: To identify characterize IFN-γ-producing we utilized IFN-γ-YFP Nur77-GFP reporter mice crossed onto an atherosclerotic background (Apoe−/−IFN-γ YFP/YFP; Apoe−/−Nur77GFP/wt), adoptive transfer tr...
Several studies have demonstrated enhanced auditory processing in the blind, suggesting that they compensate their visual impairment in part with greater sensitivity of the other senses. However, several physiological studies show that early visual deprivation can impact negatively on auditory spatial localization. Here we report for the first time severely impaired auditory localization in the...
