We provide phenotypic and functional evidence of premonocytoid dendritic cells (DCs) and preplasmacytoid DCs in blood and of corresponding DC subsets in secondary lymphoid tissue of rhesus monkeys. Subsets were identified and sorted by 4-color flow cytometry using antihuman monoclonal antibodies cross-reactive with rhesus monkey. To mobilize pre-DC subsets, fms-like tyrosine 3 kinase ligand (Fl...
AIM To evaluate the effect of a preparation with bacterial ribosomes and proteoglycans from Klebsiella pneumoniae «R» on the in vitro expression of CD11c and CD103 molecules in neutrophils from peripheral blood. METHODS Isolation of neutrophils from peripheral blood with Ficoll-Paque, incubation with R and detection of CD11c and CD103 through flow cytometry. RESULTS Six hours after the incu...
Dendritic cells (DC) represent the most potent antigen presenting cells and induce efficient cytotoxic T lymphocyte (CTL) responses against viral infections. Targeting antigens (Ag) to receptors on DCs is a promising strategy to enhance antitumor and antiviral immune responses induced by DCs. Here, we investigated the potential of CD11c-specific single-chain fragments (scFv) fused to an immunod...
Oestrogen treatments are neuroprotective in a variety of neurodegenerative disease models. Selective oestrogen receptor modifiers are needed to optimize beneficial effects while minimizing adverse effects to achieve neuroprotection in chronic diseases. Oestrogen receptor beta (ERβ) ligands are potential candidates. In the multiple sclerosis model chronic experimental autoimmune encephalomy...
Direct UV irradiation of dendritic cells and Langerhans cells reduces their Ag presenting ability. However, the effects of UV on CD11c(+) cells located distally to the point of irradiation are poorly understood. Three days after UV irradiation (8 kJ/m(2)) of BALB/c mice, bone marrow cells were isolated and cultured for 7 d with IL-4 and GM-CSF for the propagation of CD11c(+) cells. Bone marrow-...
Although dendritic cells (DCs) are adept initiators of CD4(+) T cell responses, their fundamental importance in this regard in Th2 settings remains to be demonstrated. We have used CD11c-diphtheria toxin (DTx) receptor mice to deplete CD11c(+) cells during the priming stage of the CD4(+) Th2 response against the parasitic helminth Schistosoma mansoni. DTx treatment significantly depleted CD11c(...
The respiratory tract maintains immune homeostasis despite constant provocation by environmental Ags. Failure to induce tolerogenic responses to allergens incites allergic inflammation. Despite the understanding that APCs have a crucial role in maintaining immune tolerance, the underlying mechanisms are poorly understood. Using mice with a conditional deletion of peroxisome proliferator-activat...
The underlying mechanism by which MyD88 regulates the development of obesity, metainflammation, and insulin resistance (IR) remains unknown. Global deletion of MyD88 in high-fat diet (HFD)-fed mice resulted in increased weight gain, impaired glucose homeostasis, elevated Dectin-1 expression in adipose tissue (AT), and proinflammatory CD11c+ AT macrophages (ATMs). Dectin-1 KO mice were protected...
IL-15 is required for NK cell development and homeostasis in vivo. Because IL-15 is presented in trans via its high-affinity IL-15Ralpha-chain to cells expressing the IL-15Rbetagamma complex, we postulated that certain IL-15-bearing cells must be required for NK cell homeostasis. Using IL-15(WT/WT) and IL-15(-/-) mice, bone marrow chimeras with normal cellularity, and a selective depletion of C...
مقدمه: مطالعات انجام شده در بدن انسان و حیوانات و همچنین در شرایط آزمایشگاهی، دلالت بر این دارد که سوء مصرف اوپیوئیدها ممکن است اثرات ایمونومدولاتوری مخربی بر پاسخ های ایمنی ذاتی و اکتسابی داشته باشد. سلول های دندریتیک دیده بانان سیستم ایمنی اند و به عنوان پلی میان پاسخ ایمنی ذاتی و اکتسابی عمل می کنند. کیفیت پاسخ های ایمنی تحت تاثیر عملکرد، وضعیت بلوغ و فعالیت سلول های دندریتیک قرار دارند....
