سابقه و هدف: با توسعه و پیشرفت روزافزون در زمینة ایمنی‌درمانی تومورها، امروزه توجه خاصی به درمان‌های ایمنی انواع سرطان‌ها معطوف شده است. درمان‌های بر پایة گیرنده‌های کایمری آنتی‌ژن‌ها (CARs)، یکی از انواع درمان‌های مبتنی بر سلول‌های Tی تغییریافته به‌شمار می‌رود که به‌صورت هدف‌مند تنها روی سلول‌های توموری فرد و نه سلول‌های طبیعی اثر می‌گذارد. مواد و روش‌ها: پژوهش‌ها در دهه‌های اخیر حاکی از این ا...
Chimeric antigen receptor engineered-T (CAR-T) cells also named as living drugs, have been recently known as a breakthrough technology and were applied as an adoptive immunotherapy against different types of cancer. They also attracted widespread interest because of the success of B-cell malignancy therapy achieved by anti-CD19 CAR-T cells. Current genetic toolbox enabled the synthesis of CARs ...
Introduction: Today, treatment with CAR-T cells is accepted as an effective treatment for blood malignancies. CAR-T cells are autologous T cells that are engineered by gene transfer techniques to express a chimeric antigen receptor (CAR). Despite the promising results and the approval of six CAR-T cell products; these products have not yet been approved for solid tumors. In addition, the high c...
Immunotherapy with genetically engineered T-cells that express the chimeric antigen receptor (CAR) has raised hopes for the treatment of pediatric malignancies. Although CAR T-cell development is on a fast-moving pace and evolution, the context of exploring novel targetable antigens has been neglected. In this review study, we analyze the prominent hematologic antigens targeted by engineered T-...
علی رغم علاقه زیاد به نقش اورکسین در بی دردی و وجود انشعابات زیاد به ساقه مغز، مکانی که این اثر را در ساقه مغز وساطت می کند مشخص نیست. در این مطالعه اثرات تزریق اورکسینa (1-20 نانومول، 0/5 میکرولیتر) به درون ماده خاکستری دور کاریز مغزی ((pag) (periaqueductal gray و بخش سریشکمیمیانی پیاز مغز rostral ventromedial medulla (rvm))) (شامل هسته مگنوس بزرگ (neucleus raphe magnus(nrm) و هسته ژیگانتوسل...
Novel immunotherapeutic agents targeting tumor-site microenvironment are revolutionizing cancer therapy. Chimeric antigen receptor (CAR)-engineered T cells are widely studied for cancer immunotherapy. CD19-specific CAR-T cells, tisagenlecleucel, have been recently approved for clinical application. Ongoing clinical trials are testing CAR designs directed at novel targets involved in hematologic...
Background and purpose: In recent years, immunotherapy using chimeric antigen receptor T cells (CAR T cells) has been considered as a novel and promising treatment for some diseases, especially cancer. The CAR T cell production is a multi-step, complex, time-consuming, and costly process. One of the most important steps in production of CAR T cells is expansion of these cells at appropriate num...
Autologous T cells were genetically modified to express a chimeric antigen receptor (CAR) directed toward carboxy-anhydrase-IX (CAIX) and used to treat patients with CAIX-positive metastatic renal cell carcinoma. In this study, we questioned whether the T cell maturation stage in the pre-infusion product affected CAIX CAR expression and function in vitro as well as in vivo CAR T cell numbers an...
