the immunopathology of sarcoidosis remains elusive despite years of research into this multiorgan disease.however, recent studies have provided new insights into the genetics and immune components involved in the clinical manifestation of the disease. granulomatous inflammation is due to the host immune response to a persistent poorly degradable unknown antigen.mycobacterium tuberculosis (mtb) ...

dendritic cells (dcs) are antigen presenting cells with unique capability to take up and process antigens in the peripheral blood and tissues. they subsequently migrate to draining lymph nodes where they present these antigens and stimulate naive t lympho-cytes. during their life cycle, dcs go through two maturation stages and are referred to as immature and mature cells, respectively. while im...

Several case reports on endoscopic resection of minor papilla adenomas exist in the literature. However, there are no reported cases of endoscopic resection in patients with minor papilla adenomas with associated familial adenomatous polyposis (FAP) and pancreas divisum. We report a case of a minor papilla adenoma in a patient with FAP and pancreas divisum. The case demonstrates a new associati...

background: mesenchymal stem cells (mscs) with their potential to differentiate into mesodermal and non-mesodermal lineages have several immunomodulatory characteris-tics. these properties make them promising tools in cell and gene therapy. objective: to evaluate the potential therapeutic applications of autologous msc in improving clinical manifestations of ms patients. methods: ten patients w...

background: dendritic cells (dcs) are potent antigen presenting cells for triggering of the immune reaction post transplantation. these cells are centrally involved in the initiation of t cell-dependent immune responses. objective: to compare the level of dc maturation and function in liver transplant recipients with healthy controls. methods: in this study, twelve peripheral blood samples were...

background: repeated implantation failure (rif) is one of the most intricate obstacles in assisted reproduction. the cytokine and chemokine composition of uterine cavity seem to play important roles in the implantation process. objective: to compare the cytokine profile in the endometrium of normal fertile women and those with repeated implantation failure. methods: after enzymatic digestion of...

objective(s) doxorubicin (dox), a widely used chemotherapeutic agent can give rise to serve cardiotoxicity by inducing apoptosis. curcumin, the active compound of the rhizome of curcuma longa l. has anti-inflammatory, antioxidant and anti-proliferative activities. curcumin has been identified to increase cytotoxicity in several cancer cell lines in combination with dox, but there is no study ab...

background: cytoadherence of plasmodium falciparum - infected red blood cells to endothelial cells is an important mechanism for parasite survival and a major trigger for diseases pathology. here, we de­scribe a new adhesion assay in which different cell types (cho, cho/cd36 and cho/icam-1) are at­tached to cytodex beads in a mini-column format to measure the relative sizes of various binding s...

conclusions the inhibition of tregs is a novel therapeutic approach to cure chronically hbv infected patients. however, further studies are needed to investigate the safety and efficacy of this approach. results considering the increased levels of regulatory cytokines and also regulatory t cells (tregs) during chb, it seems that these cells are deeply involved in chb infection. the inhibition o...
