Plasmacytoid dendritic cells (pDCs) regulate innate and adaptive immunity. Neurotrophins and their receptors control the function of neuronal tissue. In addition, they have been demonstrated to be part of the immune response but little is known about the effector immune cells involved. We report, for the first time, the expression and immune-regulatory function of the low affinity neurotrophin ...
OBJECTIVE Rewiring of excitatory glutamatergic neuronal circuits is a major abnormality in epilepsy. Besides the rewiring of excitatory circuits, an abnormal depolarizing γ-aminobutyric acidergic (GABAergic) drive has been hypothesized to participate in the epileptogenic processes. However, a remaining clinically relevant question is whether early post-status epilepticus (SE) evoked chloride dy...
Multicystic and unicystic ameloblastomas are benign odontogenic tumors that present distinct biological behavior. The investigation of stem cells has become an important branch of tumor biology, with several studies addressing the possible role of these cells in tumor growth, angiogenesis, progression, infiltration and invasiveness. This study evaluated the immunohistochemical expression of CD9...
The p75 neurotrophin receptor (p75NTR) is a focus for study at present. However, its function in gastric cancer was not elucidated. Here, we investigated its relation with metastasis of gastric cancer. By immunohistochemistry, we found that the positive rate of p75NTR expression in metastatic gastric cancer was 15.09% (16 of 106), which was lower compared with nonmetastatic gastric cancer (64.1...
یکی از امید بخش ترین روش های درمان سرطان، القاء آپوپتوز در سلول های سرطانی است. به همین منظور، چندین آنتی بادی آگونیست علیه گیرنده مرگ 5 (dr5) تولید شده است، که تحت ارزیابی بالینی قرار دارند. اساسا، با فعال شدن dr5 در سلول های سرطانی القاء آپوپتوز در مسیرهای داخلی و خارجی آغاز می گردد. این گیرنده در بخش خارج سلولی خود دارای چندین دومن عملکردی است، که در بین آنها دومن های غنی از سیستئین (crds) آ...
Although identified almost 20 years ago, the precise physiological role of the p75 neurotrophin receptor (p75NTR) has remained elusive. Recent studies have revealed that p75NTR is a component of three distinct receptor platforms that bind different ligands and that, under differing circumstances, facilitate cell survival, cell death, or growth inhibition. These recent developments provide new i...
The mechanisms by which neurotrophins regulate growth cone motility are unclear. We investigated the role of the p75 neurotrophin receptor (p75NTR) in mediating neurotrophin-induced increases in filopodial length. Our data demonstrate that neurotrophin binding to p75NTR is necessary and sufficient to regulate filopodial dynamics. Furthermore, retinal and dorsal root ganglion growth cones from p...
Our goal was to determine the role of the p75 neurotrophin receptor (p75NTR) in the loss of islet sympathetic nerves that occurs during the autoimmune attack of the islet. The islets of transgenic (Tg) mice in which β-cells express a viral glycoprotein (GP) under the control of the insulin promotor (Ins2) were stained for neuropeptide Y before, during, and after virally induced autoimmune attac...
این مطالعه به منظور تبیین تجربۀ خانواده های بیماران مرگ مغزی از ارتباط و آشنایی با خانواده و فرد گیرندۀ عضو به روش کیفی با رویکرد پدیدارشناسی انجام شد. به این منظور مصاحبه های بدون ساختار و عمیق با 5 خانوادۀ بیمار مرگ مغزی اهدا کنندۀ عضو که با گیرنده های اعضا ارتباط داشتند، صورت گرفت که در آن خانواده ها تجربیات خود را در خصوص این پدیده بیان کردند. داده های به دست آمده از این مصاحبه ها با استفاد...
