    • Disclosed are peptides that contain up to about 35 amino acids, including a plurality of aromatic amino acid residues and either (i) an amino acid residue that is phosphorylated or sulfated, or (ii) an amino acid comprising an ester-moiety linked via peptide bond, or both (i) and (ii), wherein the peptide is capable of self-assembly to form nanofibrils in the presence of an enzyme that hydrolyzes the phosphate group, the sulfate group, or the ester- moiety. These peptides are enzymatically responsive hydrogelators, and they can be used to form pericellular hydrogels/nanofibrils upon exposure to target cells that secrete or express a surface bound ectoenzyme having hydrolase activity suitable to induce peptide gelation. These materials, and compositions containing the same, can be used for in vitro and in vivo cellular imaging, treating cancerous conditions, collecting a secretome from a cell upon which the pericellular hydrogels/nanofibrils form, and screening the collected secretome.
    • 公开了包含多达约35个氨基酸的肽,包括多个芳族氨基酸残基和(i)被磷酸化或硫酸化的氨基酸残基,或(ii)包含通过肽连接的酯部分的氨基酸 (i)和(ii)两者,其中所述肽能够在水解磷酸基团,硫酸根基团或酯 - 部分的酶的存在下自组装形成纳米原纤维。 这些肽是酶促响应的水凝胶因子,当暴露于分泌或表达具有适于诱导肽胶凝的水解酶活性的表面结合的胞外酶的靶细胞时,它们可用于形成胞外水凝胶/纳米纤丝。 这些材料和含有它们的组合物可以用于体外和体内细胞成像,治疗癌症病症,从胞上水凝胶/纳米原纤维形成的细胞中收集分泌组,并筛选收集的分泌组。
