Objective: The main function of IL-12 is differentiation of naive T cells intoTh1 cells and TGF-β is a powerful immunoregulatory cytokine. The immunomodulatory and anti-inflammatory properties of ginger have also been reported in some studies. The aim of this study was to evaluate the effects of ginger extract on the expression of IL-12 and TGF-β in a model of experimental autoimmune encephalom...

Experimental autoimmune encephalomyelitis (EAE) is an animal model for multiple sclerosis (MS). EAE and MS are characterized by CNS inflammation, demyelination and neurodegeneration. The inflammatory response occurring within the CNS leads to glial activation, dysfunction and death, as well as axonal damage and neurological deficit. Although the pathogenic mechanisms involved in EAE/MS are not ...

Herpes simplex virus type 1 (HSV-1) has properties that can be exploited for the development of gene therapy vectors. The neurotropism of HSV enables delivery of therapeutic genes to the nervous system. Using a bacterial artificial chromosome (BAC), we constructed an HSV-1(17(+))-based replicative vector deleted of the neurovirulence gene γ134.5, and expressing leukemia inhibitory factor (LIF) ...

Studies in multiple sclerosis have demonstrated that normal-appearing white matter can harbor pathological changes. Here we investigated the effects of neuroinflammation, modeled by experimental autoimmune encephalomyelitis (EAE) on neural stem/progenitor cells (NPCs) located distally to inflammatory foci. We observed that EAE-derived NPCs had a lower capacity to differentiate into oligodendroc...

objective: the incidence of breast cancer is approximately one million which makes this cancer one of the most common among women worldwide. breast cancer comprises 7% of the total death rate caused by cancers. several strategies that use tumor-associated antigen (taa) vaccination and early detection of breast cancer are clinically being developed. breast cancer is caused by increased over expr...

It has been reported that the spinal cord possesses Gonadotropin-releasing hormone (GnRH) receptor and that GnRH has neurotrophic properties. Experimental autoimmune encephalomyelitis (EAE) causes neurodegeneration in spinal cord. Thus, the present study was designed to determine whether administration of GnRH reduces the severity of EAE. The clinical signs of locomotion, axonal morphometry and...

background: niche cells, regulating spermatogonial stem cells (sscs) fate are believed to have a reciprocal communication with sscs. the present study was conducted to evaluate the effect of ssc elimination on the gene expression of glial cell line-derived neurotrophic factor (gdnf), fibroblast growth factor 2 (fgf2) and kit ligand (kitlg), which are the main growth factors regulating sscs deve...

background: peroxisome proliferator activated receptor gamma (pparγ), a member of nuclear receptor superfamily, comprises two isoforms in mouse. these two isoforms are encoded by different mrnas, which are arisen by alternative promoter usage. there are two promoter regions upstream of pparγ gene. a 3 kb fragment, containing several transcription factor binding sites, acts as pparγ1 promoter re...

calorie restriction through ingesting no or minimal amounts of food and caloric beverages for periods of time is called fasting. fasting can affect body through changing in physical and metabolic adaptations, as well as mineral and hormonal status. however, psychological effects and sometimes medical complications are likely in case of inappropriate fasting. fasting is associated with changes i...

background: vast variety of intermediate factors including cell cycle regulators, growth factors, transcription factors, and signaling pathways are involved in hematopoietic stem cell (hsc) commitment and differentiation into distinct lineages. vhl, ecad, and runx3 are among these. epigenetics is currently introduced as a potential mechanism to control the gene regulation. the aim of this study...
