Interleukin-10 production by effector T cells: Th1 cells show self control
Interleukin (IL)-10 is a cytokine that modulates both innate and adaptive immunity, primarily by exerting antiinflammatory effects. IL-10 was originally thought to be produced only by T helper (Th)2 cells, but is now known to be made by a variety of cell types. During many infections, CD4(+) T cells produce both interferon (IFN)-gamma, the signature Th1 cytokine, and IL-10. New data now show th...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولCXCR3+ Regulatory T Cells Control TH1 Responses in Crescentic GN.
Chemokines and chemokine receptors are implicated in regulatory T cell (Treg) trafficking to sites of inflammation and suppression of excessive immune responses in inflammatory and autoimmune diseases; however, the specific requirements for Treg migration into the inflamed organs and the positioning of these cells within the tissue are incompletely understood. Here, we report that Tregs express...
متن کاملDamaging Loss of Self-Control by Stressed β-Cells
Only 15–20% of obese individuals with severe insulin resistance develop type 2 diabetes mellitus (T2DM). In healthy individuals, b-cell compensation ensures that enhanced glucosestimulated insulin secretion (GSIS) balances the degree of insulin resistance. However, individuals predisposed to T2DM are unable to secrete the increased insulin required to compensate for insulin resistance in order ...
متن کاملPeritoneal Cavity Is Dominated by IFNγ-Secreting CXCR3+ Th1 Cells
The chemokine receptor CXCR3, which was shown to take part in many inflammatory processes, is considered as a Th1 specific marker. Here, we show in a mouse model that CXCR3 expressing CD4(+) cells preferentially migrate to the peritoneal cavity under steady-state conditions. The peritoneal cavity milieu leads to an up-regulated expression of CXCR3. However, blocking of known ligands of this che...
