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.
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 T H 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 T H cells. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
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. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Animal administration
Mice 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. aladdin has not independently confirmed the accuracy of these methods.
