Background: Microparticles (MPs) are small vesicles released from the cell membrane. Accordingly, these contain active molecules to mediate biological processes, including cell proliferation and cell cycle progression. The fusion of myeloma cell lines with immunized B lymphocytes is a critical step of hybridoma technology. MPs modulate lymphoproliferation, thereby facilitating B cell expansion ...
مقدمه: نقص ایمنی متغیر شایع (common variable immunodeficiency یا cvid)، فراوان ترین نارسایی ایمنی اولیه از نظر بروز علایم بالینی و مجموعه شرایط ناهمگنی است که با کمبود ارثی آنتی بادی (هایپوگاماگلوبولینمی) از حداقل دو ایزوتیپ ایمونوگلوبولین به همراه اختلال در بلوغ سلول های b و جهش سوماتیک، کاهش تعداد سلول های خاطره ی تعویض کلاس شده و نشده در گردش خون و اغلب با نبود پلاسماسل شناخته می شود. b-cell...
non-hodgkin lymphoma usually presents with generalized lymphadenopathy, but it can also involve any part of the human body. lymphomatous involvement of muscles is a rare presentation and has been reported to occur in only 1.1% in non-hodgkin lymphoma. here we, present a 32 year-old iranian man with primary involvement of spleen, bone, bone marrow and muscle, mimicking soft tissue sarcoma; core ...
primary cardiac lymphoma is a rare disease which mainly found in elderly men. it is usually a b-cell non-hodgkin’s lymphoma which primarily located in the heart and may involve the pericardium. the common presentations include massive pericardial effusion and heart failure. clinical diagnosis is often delayed in these patients and prognosis is dismal. we report a case of a 70-year-old man prese...
objective(s): oxidative stress has been established as a key cause of alcohol-induced hepatotoxicity. licochalcone b, an extract of licorice root, has shown antioxidative properties. this study was to investigate the effects and mechanisms of licochalcone b in ethanol-induced hepatic injury in an in vitro study. materials and methods: an in vitro model of ethanol-induced cytotoxicity in brl cel...
Background: Acute lymphoblastic leukemia (ALL) is the most common cancer in the pediatric population. With modern treatments, the chance of the complete recovery is nearly 100%. The most important prognostic factors are appropriate treatment protocol and determination of patient risk factors based on clinical, morphological, immunological and cytological characteristics. In this study we review...
background : there are only a few reports that exist regarding primary non-hodgkin lymphoma of the genital tract. in this article, one case of primary b-cell type non-hodgkin lymphoma (nhl) of the cervix is presented. case history: a 45 year-old woman presented bloody vaginal discharge. upon vaginal examination, the cervix was found to be enlarged. cervical biopsy revealed b-cell type non-hodg...
Transforming growth factor beta (TGF-b) is a mediator released by nearly all cell types. It has suppression activity on the immune system, but exactly how this effect is carried out is not clear. Previous experiments showed that IgG interacts with or carriers active TGF-b, that could suppresses cytotoxic T-cell responses to an immunogenic tumor in mice. Since T cell receptor (TCR) has structura...
Introduction: Transplantation of embryonic ventral mesencephalic (VM) dopamine neurons into the striatum is a currently explored therapeutic strategy for treatment of patients with patients with Parkinson's disease (PD). However, this strategy has been limited with poor cell survival, generally ranging from 5-20%. In this study, we investigated the effect of potassium channel blocker of tetr...
