生物活性

Lacto-N-neotetraose (LNnT) is an endogenous metabolite. Lacto-N-neotetraose can inhibit TNF-α induced IL-8 secretion in immature epithelial cells. Lacto-N-neotetraose has anti-inflammatory avtivity, and can improve the wound closure[1][2][4].

IC50 & Target

Endogenous Metabolite[1], TNFR1[2].

体外研究
(In Vitro)

Lacto-N-neotetraose (5 mg/mL, 24 h) induces IL-8 secretion in T84 cells[2].
Lacto-N-neotetraose (5 mg/mL, 24 h) reduces TNF-α induced IL-8-secretion with 38% in FHs 74 Int cells[2].
Lacto-N-neotetraose binds TNFR1 (Tumor necrosis factor receptor 1) with a Kd value of 900 ± 660 nM[2].
Lacto-N-neotetraose (5 mg/mL, 24 h) attenuates TNF-α induced inflammation by TNFR1 ectodomain shedding in FHs 74 Int cells[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

Lacto-N-neotetraose (100 μM, intratracheal administration for 24 h) reduces the abundance of Streptococcus pneumonia in the lungs of pneumonia rabbits[3].
Lacto-N-neotetraose (100/200 μg, Intradermal injection, at 3, 7, 14, and 21 days post-surgery) increases the wound closure rate on day 7 post-wounding[4].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Rabbit model of pneumonia[3]
Dosage: 100 μM
Administration: Intratracheal administration for 24 h
Result: Decreased by ~2 logs the bacterial load in the lung at 48 h after challenge.
Eliminated the extensive, edematous right middle lobe lesion evident at 48 h in control animals.
Animal Model: Mice with symmetric full-thickness wounds
Dosage: 100, 200 μg
Administration: Intradermal injection, at 3, 7, 14, and 21 days post-surgery.
Result: Exhibited better healing score, follicle formation, and lower epidermal thickness index (H&E staining).

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.
