从 CX3CR1GFP/+ 小鼠中分离出成年小胶质细胞和血液单核细胞,并分析其受体水平。作者发现,与血液来源的细胞相比,常驻的成年小胶质细胞表达更高水平的 Tgfbr1,而两种细胞类型中的 Tgfbr2 水平相似(图 2D)。成年小胶质细胞上 Tgfbr1 的较高表达增强了 TGFβ1 与这些常驻骨髓细胞命运的潜在相关性。 由于之前的数...
TGF-β配体和细胞膜上的TGFBR2结合,一旦结合TGFBR2磷酸化并激活TGFBR1;活化的TGFBR1依次磷酸化并激活受体活化的SMADs(R-SMADs:SMAD2和SMAD3);SMAD7和R-SMADs竞争与TGFBR1相互作用,从而阻止R-SMAD的激活和信号的正常传导。 激活的R-SMADs与TGFBR1分离,从而与通用SMAD...

一旦在LAP释放后被激活,tgf - β -1通过与tgf - β受体(TGFBR1和TGFBR2)结合,转导信号。虽然tgf - β -1在许多细胞中都有表达,但由于它的激活受到潜伏相关肽链(LAP)和“环境分子"的精细调控,因此在细胞环境中只有非常局限的作用范围。在骨重塑中发挥重要作用:作为成骨细胞形成的有力刺激,导致成骨细胞的趋化...
(humoral) response, which relies on molecules such as IL10 and transforming growth factor-β (TGFβ)4,5. It is also known that TGFβ binds to two receptors (TGFBR1 and TGFBR2) that act as important regulators of downstream effectors5. More recently, a novel immune-response pathway ...
Furthermore, genetic variations along the TGFβ1 signalling pathway are associated with coronary artery aneurysm formation and aortic root dilation in Kawasaki diseases [60], whereas mutations in genes of TGFβ1 signalling pathway (TGFBR1, TGFBR2[61, 62], and SMAD3[63]) or TGFβ1 inhibitor ...

TGF-β发挥作用需要和细胞膜上的TGFBR1、TGFBR2两种受体结合。实验室可以通过Western blot或者流式细胞术检测这些受体在细胞表面的表达量。比如在乳腺癌研究中发现,某些耐药细胞系的TGFBR2表达量下调,这可能和肿瘤细胞逃逸TGF-β的生长抑制效应有关。另外,受体磷酸化水平更能反映信号通路的激活状态。当TGF-β与受体...
We utilized a series of conditional mutants to ablate the TGFβ receptors Tgfbr1 (Alk5) and Tgfbr2 in LECs. To analyze lymphatic defects, we developed a novel, whole-mount embryonic skin imaging technique to visualize sprouting lymphangiogenesis and patterning at the lymphatic network level. Loss...
