COA 产品使用指南

Phosphatidylserine (Phospholipids) 是一种保守的抗炎和免疫抑制信号。Phosphatidylserine 参与膜易位和蛋白激酶C的激活,通过与 PIP3 的相互作用参与 Akt 信号传导。Phosphatidylserine 的局部暴露可以与补体和其他蛋白质相互作用,在突触细化的发育关键时期促进小胶质细胞吞噬。Phosphatidylserine 在胞外可以促进血液凝固,并作为“吃掉我”信号来清除凋亡细胞。 Phosphatidylserine 可以通过诱导 TGF-β 分泌来抑制组织中的炎症,抑制免疫反应。

生物活性

Phosphatidylserine (Phospholipids) is a well-conserved anti-inflammatory and immunosuppressive signal. Phosphatidylserine is involved in membrane translocation and the activation of protein kinase C, participating in Akt signaling through its interaction with PIP3. The local exposure of Phosphatidylserine can interact with complement and other proteins, promoting microglial phagocytosis during critical periods of synaptic refinement. Phosphatidylserine can promote blood coagulation in the extracellular environment and acts as a "eat me" signal to clear out apoptotic cells. Phosphatidylserine can suppress inflammation in tissues by inducing TGF-β secretion and inhibiting immune responses[1][2][3][4][5].

体内研究
(In Vivo)

Phosphatidylserine (0.5 mg 脂质体; 单剂量; 皮下注射) 可以与 PC 和胆固醇以 30:30:40 的摩尔比组成脂质体,脂质体通过结合并增强 Phosphatidylserine 受体的激活来抑制体内免疫反应[2]

Animal Model: BALB/cAnN and C57BL/6 male mice[2].
Dosage: Phosphatidylserine (PS) liposomes (0.5 mg of total lipid, PS-containing liposomes consisted of 30:30:40 molar ratio PS to PC to cholesterol)
Administration: Subcutaneous injection (s.c.); single dose
Result: Inhibited responses to Ags as determined by decreased draining lymph node tissue mass, with reduced numbers of total leukocytes and Ag-specific CD4+ T cells.

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.
