生物活性

WYRGRLC is a type II collagen-targeting peptide. WYRGRLC specifically binds to type II collagen α1 in articular cartilage in a sequence-dependent manner. WYRGRLC inhibits the binding of WYRGRL-displaying phage (C1-3) to articular cartilage in a sequence-specific manner. WYRGRLC can act as a retention enhancer to improve the cartilage-targeting ability of polymeric nanoparticles and liposomal nanoplatforms, facilitating the delivery of Rapamycin (HY-10219) to chondrocytes. WYRGRLC can be used in studies related to osteoarthritis[1][2].

体外研究
(In Vitro)

WYRGRLC (0-1 μM) 可强效且序列特异性地抑制展示 WYRGRL 的噬菌体与牛软骨的结合,其 IC50 为 140 nM[1]
WYRGRLC (15 mg; 1 h) 可特异性结合 II 型胶原 α1 链,后者是牛软骨中含量丰富的细胞外基质蛋白[1]
WYRGRLC 修饰的 C6@PEG-PA@P-Lipo 可增强大鼠软骨细胞 (RCCs) 的靶向细胞摄取[2]
WYRGRLC 修饰的 P-Lipo 可附着于猪软骨组织的表层,但由于其粒径较大,深层渗透能力有限[2]

体内研究
(In Vivo)

WYRGRLC 作为靶向Ⅱ型胶原的脂质体修饰肽,可延长 RP@PEG-PA@P-Lipo 递送系统在关节内的滞留时间,从而有效抑制前交叉韧带切断 (ACLT) 诱导的骨关节炎 (OA) 大鼠的滑膜炎、维持软骨结构与代谢水平并减少软骨细胞凋亡,在所有 ACLT 治疗组中取得最低的 OARSI 评分[2]

Animal Model: Male SD rats (210-230 g)[2]
Dosage: 100 μL
Administration: intra-articular injected, once
Result: Enabled prolonged joint retention of the RP@PEG-PA@P-Lipo delivery system, contributing to effective suppression of synovitis, preservation of cartilage structure and metabolism, and reduction of chondrocyte apoptosis.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
