生物活性

OVA Peptide (323-339) represents a T and B cell epitope of Ovalbumin (Ova), which is important in the generation and development of immediate hypersensitivity responses in BALB/c mice.

体外研究
(In Vitro)

When pulsed with 0.01 μM of OVA Peptide (323-339), M2-expressing B cells lead to an increase in the number of TH cells mobilizing calcium, compared to M2Y-expressing B cells. To assess if M2-expressing B cells are also able to promote stronger individual responses, we quantified the 405/530 ratio MFI of responding TH cells[1].

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

体内研究
(In Vivo)

OVA Peptide (323-339) represents a T and B cell epitope of OVA, which is important in the generation and development of immediate hypersensitivity responses in BALB/c mice. Daily aerosolization of OVA Peptide (323-339) for 20 minutes over a period of 10 days has been as effective in the stimulation of a serum anti-OVA IgE antibody response as sensitization to native OVA by the same route. After sensitization to native OVA, the majority of the IgE anti-OVA response is directed against OVA Peptide (323-339). Evaluated by hematoxylin/eosin and major basic protein immunohistochemical stainings, OVA and OVA Peptide (323-339) induce similar lung inflammation. Interestingly, significant serum total IgE and OVA-specific IgE are observed in OVA mice when compared to saline control. OVA Peptide (323-339) mice show higher serum OVA-specific IgE, OVA Peptide (323-339)-specific IgE, IL-4 and lower IFN-γ similar to OVA mice. The proliferative response to OVA is found in cultured splenocytes of both OVA and OVA Peptide (323-339) mice, while the similar proliferative response to OVA Peptide (323-339) is only observed in the splenocytes of OVA Peptide (323-339)-sensitized and challenged mice. Although OVA Peptide (323-339) induces a Th2-like response in the mouse model as does OVA, OVA Peptide (323-339) has clearly limited immunogenic potency to activate OVA-sensitized and challenged mice splenocytes, unlike OVA[2].

Cell Assay
[1]

A20 B cell lines are loaded, or not, with different concentrations of OVA Peptide (323-339) overnight. Cells are then conjugated with purified mouse CD4+ T cells and incubated for 20 h. After the 20 h incubation period, supernatant is recovered and stored at -20°C. IFN-γ production is quantified in the supernatants by sandwich ELISA. 96-well plates are analyzed. T cells cultured for two to four days in the presence of 3 μg/mL of anti-CD3 antibody are used as positive control of T cell activation. B cells cultured for 48 h in the presence of 2.5 μg/mL of anti-CD40 antibody and 5 μg/mL of the F(ab’)2/F(ab) portion of an anti-mouse IgG antibody are used as positive control for B cell activation[1].

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

Animal Administration
[2]

Mice[2]
Fifty-one 8-week-old female BALB/c mice are randomly divided into three groups: OVA, OVA 323-339 and saline. They are intraperitoneally injected with 25 μg OVA or OVA Peptide (323-339) absorbed on 300 μg Alum or saline on days 0, 7, 14. On days 21-23, all groups are challenged intranasally with 20 μL of 1% OVA, 1% OVA Peptide (323-339) and saline, respectively. On days 0, 7, 14, mice are intraperitoneally injected with 25 μg OVA or OVA Peptide (323-339) absorbed on 300 μg Alum, or saline; on days 21-23, all groups are challenged intranasally with either 20 μL of 1% OVA, 1% OVA Peptide (323-339) or saline. On day 28, after killing, splenocytes are isolated and cultured under the stimulus of each allergen or medium.

生物活性

Chikusetsusaponin IVa a major active ingredient of triterpenoid saponins, exerts antithrombotic effects, including minor hemorrhagic events. This appears to be important for the development of new therapeutic agents. a novel AMPK activator that is capable of bypassing defective insulin signalling and could be useful for the treatment of T2DM or other metabolic disorders. IC50 Value: 199.4 ± 9.1 μM (inhibiting thrombin-induced fibrinogen clotting) Target: In vitro: Using biochemical and pharmacological methods, it proves that chikusetsusaponin IVa prolongs the recalcification time, prothrombin time, activated partial thromboplastin time, and thrombin time of normal human plasma in a dose-dependent manner; inhibits the amidolytic activity of thrombin and factor Xa upon synthetic substrates S2238 and S2222; inhibits thrombin-induced fibrinogen clotting (50% inhibition concentration, 199.4 ± 9.1 μM); inhibits thrombin- and collagen-induced platelet aggregation. Chikusetsusaponin IVa can also preferentially inhibits thrombin in a competitive manner (K(i)=219.6 μM) [1]. Chikusetsusaponin IVa suppresses the production of iNOS, COX-2, IL-1β, IL-6, and TNF-α in LPS-stimulated THP-1 cells likely by inhibiting NF-κB activation and ERK, JNK, and p38 signal pathway phosphorylation [2]. In vivo: Studies were performed on type 2 diabetic mellitus (T2DM) rats given CHS for 28 days to test the antihyperglycemic activity. Oral administration of CHS dose-dependently increased the level of serum insulin and decreased the rise in blood glucose level [3].
