细胞因子介导的单核细胞浸润参与多种病理过程。可以在微环境中隔离细胞释放的趋化因子的免疫隔离基质可以延长植入材料的活力和功能。我们描述了一种基于自组装肽的水凝胶,其可以捕获由免疫细胞和基质细胞在细胞外空间中释放的细胞因子CCL2。剪切响应基质可以吸收并保留浸润单核细胞的趋化性及其分化为吞噬巨噬细胞所需的这种信号分子。这种胆碱螯合生物材料可用作递送外源性植入物或细胞悬浮液用于组织再生的免疫材料,而无需施用全身性免疫抑制剂。我们的工作突出了纳米纤维肽水凝胶用于调节组织壁龛中的生物反应的多功能性。
Cytokine-directed monocyte infiltration is involved in multiple pathological processes. Immuno-isolating matrices that can sequester cell-released chemokines in a microenvironment may prolong the viability and functionality of implanted materials. We describe a self-assembling peptide-based hydrogel that can capture the cytokine CCL2 released in the extracellular space by immune cells and stromal cells. The shear-responsive matrix can absorb and retain this signaling molecule needed for the chemotaxis of the infiltrating monocytes and their differentiation into phagocytic macrophages. Such cytokine-sequestering biomaterials may be useful as adjunctive materials with the delivery of exogenous implants or cell suspensions for tissue regeneration, without the administration of systemic immunosuppressants. Our work highlights the versatility of nanofibrous peptide hydrogels for modulating the biological response in tissue niches.
