Background: Regulatory T cells (Tregs) have been investigated intensively for some decades. These cells regulate the immune system, prevent overactivated immune responses and can be used therapeutically. For rheumatoid arthritis (RA), understanding the functions and status of Tregs is an important step for understanding immune regulation in this autoimmune disease. Methods: We investigated the ...

Objective(s) The aim of this study was to characterize the hepatitis B virus surface protein genotypes and sequence variations among hepatitis B virus surface antigen (HBsAg) positive chronic patients in Hormozgan province, south of Iran. Materials and Methods A total of 8 patients enrolled in this study. The surface gene was amplified and directly sequenced. Genotypes and nucleotide/amino acid...

conclusions fmf should be considered in patients who present with alopecia, acne like lesions, cysts and comedones in older ages with a spectrum of histologic changes. we emphasize for any time it should be under-recognized. introduction folliculotropic mycosis fungoides (fmf) is a variant of mycosis fungoides characterized by the presence of folliculotropic atypical tcells infiltrates, often w...

Background and aims: Vitamins are essential constituents of our diet that Longley have been known to influence the immune system. Vitamin D3 and B9 have received particular attention in recent years as these vitamins have been shown to have an unexpected and crucial effect on the immune response. 1, 25(OH)2D3 metabolizing enzymes and vitamin D r...

Background: Mesenchymal stem cells (MSCs) are considered as effective therapeutic cells in transplantation due to their immunomodulatory activities. However, precise mechanism of MSCs immunomodulatory activity is not completely understood. Objectives: To study the role of Immunoglobulin-like transcripts-3 (ILT3) immunomodulatory receptor in immune tolerance induced by MSCs in skin transpla...

gδ T-cells contribute importantly to tumor immunosurveillance and are activated by phosphoantigen intermediates of the mevalonate pathway that are commonly over-produced in cancer cells. To potentiate this, phosphoantigen levels can be boosted using zoledronic acid (ZA). However, in vivo delivery of ZA to the tumour is inefficient owing to its poor pharmacokinetic properties. Here, we set out t...

We have examined the properties and intracellular localization of acetylcholine receptors in the C2 muscle cell line and in a variant (T-) that accumulates AChR intracellularly. On immunoblots, the subunit structures of the AChR from wild-type and Tcells were similar except that the 3' and t5 subunits of the variant AChR had altered mobilities. Digestion with endoglycosidases H and F demonstrat...
