هدف: کشت سلول های اسپرماتوگونی و تولید سلول های پر توان embryonic stem cells (es like cells) که دارای قابلیت بازسازی و تولید هرسه نوع لایه زایای جنینی می باشند، این سلول ها را به عنوان منبع کافی و جدیدی برای سلول درمانی و ترمیم در بیماریها از جمله بیماریهای نورودژنراتیو پیشنهاد می دهد. در تحقیق حاضر تمایز سلول های اسپرماتوگونی موش به سلول های شبه الیگودندروسیت و نقش آنها درمیلین سازی پس از پیون...
Multiple sclerosis is an autoimmune disease of the central nervous system which its main characteristic is an inflammation and demyelination and subsequent, neural degeneration. Many studies have shown that inflammation causing neuronal demyelination. MS is the most common cause of chronic neurological disability in during youth which the prognosis is that can be death. Platelet activating fact...
Pathogen recognition by Toll-like receptors (TLRs) initiates innate immune responses that are essential for inhibiting pathogen dissemination and for the development of acquired immunity. The TLRs recognize pathogens with their N-terminal ectodomains (ECD), but the molecular basis for this recognition is not known. Recently we reported the x-ray structure for unliganded TLR3-ECD; however, it ha...
RATIONALE Endothelial dysfunction and atherosclerosis are chronic inflammatory diseases characterized by activation of the innate and acquired immune system. Specialized protein receptors of the innate immune system recognize products of microorganisms and endogenous ligands such as nucleic acids. Toll-like receptor 3 (TLR3), for example, detects long double-stranded RNA and is abundantly expre...
Endogenous neurosteroids have rapid actions on ion channels, particularly GABAA receptors, which are potentiated by nanomolar concentrations of 3 -hydroxypregnane neurosteroids. Previous evidence suggests that 3 -hydroxypregnane steroids may competitively antagonize potentiation induced by their 3 diastereomers. Because of the potential importance of antagonists as experimental and clinical too...
Marek's disease virus (MDV) is an α-herpesvirus that causes immune suppression and T lymphoma in chickens. Toll-like receptor 3 (TLR3) is critical for the host immune response against MDV infection. Previously, our team demonstrated that pre-treatment of TLR3 agonist poly (I:C) inhibited Marek's disease virus infection in chicken embryo fibroblasts (CEFs). However, whether TLR3 inhibits the agg...
Pharmacologic agents to enhance liver regeneration after injury would have wide therapeutic application. Based on previous work suggesting inhibition of bone morphogenetic protein (BMP) signaling stimulates liver regeneration, we tested known and novel BMP inhibitors for their ability to accelerate regeneration in a partial hepatectomy (PH) model. Compounds were produced based on the 3,6-disubs...
Background & Aims: Breast cancer is the most prevalent malignancy in women. A few articles describe a marked decrease in the levels of ferroportin in breast cancer cells.The presented results demonstrate convincingly the incredible diagnostic and prognostic value of ferroportin expression in breast cancer and suggest that determination of this molecular marker maybe used as guidance toward ind...
OBJECTIVE A relationship between the pathogenesis of some cancers and growth hormone, insulin-like growth factor-1 and insulin-like growth factors binding protein-3 has been shown. Our aim was to evaluate the expression of growth hormone receptor, insulin-like growth factor-1 receptor and insulin-like growth factors binding protein-3 in actinic keratosis, basal cell carcinoma and squamous cell ...
