Allogeneic cord blood (CB) transplantation is associated with less severe graft-versus-host disease (GvHD), thought to be due to the immaturity of CB T cells, but how T cells interact with host and donor-derived dendritic cells (DCs) to initiate GvHD has not been elucidated. We therefore investigated the responses of CB and adult blood CD4(+) T cells co-cultured with adult host DCs of different...
Background: Given the high prevalence of type II diabetes and its complications, the evidence regarding the beneficial effects of probiotic yogurt on some cardiovascular biomarkers in diabetic patients is worthy of investigation. Aim: To investigate the effect of probiotic yogurt on blood glucose level and cardiovascular biomarkers in patients with type II diabetes. Method:This randomized, clin...
We recently demonstrated that lymph nodes (LNs) PD-1+/T follicular helper (Tfh) cells from antiretroviral therapy (ART)-treated HIV-infected individuals were enriched in cells containing replication competent virus. However, the distribution of cells containing inducible replication competent virus has been only partially elucidated in blood memory CD4 T-cell populations including the Tfh cell ...
We have recently shown that the leukotriene B(4) (LTB(4))-BLT1 pathway is important in early effector T-cell recruitment in mouse models of inflammation. Here we characterize the phenotype and function of human peripheral blood BLT1(+) T cells in health and illustrate their involvement in asthma and acute infection. In healthy individuals, BLT1(+) T cells are a rare peripheral blood T-cell popu...
T cell responses to viruses are initiated and maintained in tissue sites; however, knowledge of human antiviral T cells is largely derived from blood. Cytomegalovirus (CMV) persists in most humans, requires T cell immunity to control, yet tissue immune responses remain undefined. Here, we investigated human CMV-specific T cells, virus persistence and CMV-associated T cell homeostasis in blood, ...
Equine piroplasmosis is a tickborne disease of equids with worldwide distribution, caused by Theileria equi and Babesia caballi. The aim of this study was molecular detection of T. equi and B. caballi in donkeys in northeastern Iran and investigate the association between positivity of piroplasm infection and host-related factors. In the present study, Blood samples were collected from 106 appa...
Patients with acquired immunodeficiency syndrome (AIDS) present impaired colony growth and in vitro differentiation capacity of peripheral blood and bone marrow T colony-forming cells (T-CFC). We show that peripheral blood, bone marrow, and lymph node T-CFC from patients with persistent lymphadenopathy syndrome (LAS), a syndrome that can precede AIDS, displayed similar abnormalities. Indeed, pe...
The "conventional" NK1.1(-) T cells from mouse blood and marrow were compared with regard to surface receptors, cytokine secretion, and function. Most blood NK1.1(-) CD4(+) and CD8(+) T cells expressed the naive CD44(int/lo)CD62L(hi)CD45RB(hi) T-cell phenotype typical of those in the peripheral lymphoid tissues. In contrast, most marrow NK1.1(-) CD4(+) and CD8(+) T cells expressed an unusual CD...
background: ovarian cancer is the fifth leading cause of death from malignancy in women. cd4 +cd25+foxp3+ regulatory t (treg) cells are a subset of t lymphocytes with great inhibitory impact on immune response. objectives: to investigate the percentage of cd4 +cd25+foxp3+ regulatory t cells in the peripheral blood of the iranian patients with epithelial ovarian cancer compared to healthy women ...
آویشن (Thymus) از تیره Lamiaceae گیاهی است چند ساله که بهدلیل خاصیت دارویی از اهمیت بالایی برخوردار است. بذرهای پنج جمعیت متعلق به چهار گونه T. Lancifolius،T. daenensis subsp. daenensis (دو نمونه)، T. fedtschenkoiو pubescens .Tکشت گردید و پس از جوانهزنی بذرها از مریستم انتهایی ریشه برای مطالعات کاریوتیپی استفاده شد. نتایج نشان داد که تعداد کروموزوم پایه در تمام جمعیتهای مورد بررسی 15= x اس...
