Introduction: Neuropathic pain may be due to a primary insult to the peripheral or central nervous system. In this situation, Hyperalgesia and Allodynia are the results of prostaglandins and cytokines release in the spinal cord. It seems that immune cells play an importat role in the induction and maintenance of chronic pain. Compared to selective CoxII inhibitors, nimesulide, a highly select...

Viruses interact with various permissive and restrictive factors in host cells throughout their replication cycle. Cell lines that are non-permissive to viral infection have been particularly useful in discovering host cell proteins involved in viral life cycles. Here we describe the characterization of a human myeloid leukemia cell line, KG-1, that is resistant to infection by retroviruses and...

garlic and onions as dietary constituents and medicines have been used for many disorders which dates back to the early civilization. it has been shown that different species of allium have immunomodulating effects. in this study, we sought to determine if methanolic and chloroformic extracts of allim fistulosum l. (leek) have any effect on cell-mediated immune response in mice. methanolic and ...

background: the seladin-1 (selective alzheimer disease indicator-1), also known as dhcr24, is a gene found to be down-regulated in brain region affected by alzheimer disease (ad). whereas, hair follicle stem cells (hfsc), which are affected in with neurogenic potential, it might to hypothesize that this multipotent cell compartment is the predominant source of seladin-1. our aim was to evaluate...

Most anti-cancer immunotherapeutic strategies involving dendritic cells (DC) as vaccines rely upon the adoptive transfer of DC loaded with exogenous tumour-peptides. This study utilized human acute myeloid leukemia (AML) cells as progenitors from which functional dendritic-like antigen presenting cells (DLC) were generated, that constitutively express tumour antigens for recognition by CD8(+) T...

background: treatment of cancer patients using conventional chemotherapy causes serious side effects and, at best, merely extends the patient’s lifespan by a few years. the potential of alternative therapies may therefore be of great benefit in cancer control. the effect of trigonella foenum graecum seed extract has been previously reported on some neoplastic cells. here, its effect is evaluate...

In this article, we report a new method-a sonication method to disperse iron oxide nanoparticles into smaller nanoparticles and make gold ions absorb onto the surface or trapped in the micropores of the iron oxide nanoparticles using sonication action. By using quick reduction of ascorbic acid and post-HCI solution treatment, gold covered magnetic nanoparticles (mGNPs) with spherical morphology...

Dendritic cells (DCs) progress through distinct maturational phases; immature DCs capture Ag while mature DCs are optimized for Ag presentation. Proper control of immunity requires regulated compartmentalization of MHC class II molecules. We report that DCs also regulate MHC class I trafficking throughout maturation. Although mature human DCs express high levels of surface MHC class I, immature...
