- detection of cytokines such as IL-4 and L-13 indicates a mixed Th1 and Th2 profile or regulation between the two profiles.
- the high production of GM-CSF by Oils A and B is also an element that can accelerate a microbial response. Indeed, GM-CSF, at the central and peripheral levels, increases the number or the functionality of cells of the monocyto / macrophage lineage, thus potentiating the anti-infectious responses.
- Table 7 details the effects of the adjuvants on the cytokine levels in the culture supernatants of dendritic cells cocultured with autologous lymphocytes and without prior antigen presentation (PPD).
- Table 8 details the effects of the adjuvants on the cytokine levels in the culture supernatants of the dendritic cells cocultured with the autologous lymphocytes and after antigen presentation (PPD).
- Oils A and B direct the response towards a Th1 profile with an increase in the levels of TNF-a, of IFN-g and IL-2.
- an increase in the level of GM-CSF is observed.
- Oils A and B are distinguished from other adjuvants tested at the cytokine level. Indeed, the other three adjuvants generate little or no modulations of the cytokines tested.
- Oils A and B promote the proliferation / activation of lymphocytes brought into contact with cells presenting antigens, whether they are macrophages or dendritic cells, in the presence or absence of an antigen such as PPD.
- Oils A and B exhibit a specific profile. On the one hand, they do not modulate the expression of CD1a, specific for dendritic cells.On the other hand, Oils A and B, and in particular Oil A, increase the expression of CD83, a marker of maturation of dendritic cells.
- Oils A and B exhibit a specific profile, oriented towards Th1 type responses for lymphocytes and M1 for macrophages. They also lead to maturation of dendritic cells. These profiles, like the increased macrophage synthesis of GM-CSF, are believed to promote an anti-infectious response, a role expected of an adjuvant.
- Example 3 preparation of an emulsion comprising the adjuvant composition of the invention - evaluation of the stability of the emulsion
- the oil and the surfactant of the fatty phase are introduced into a test tube in the proportions indicated in Table 11.
- the test tube is stirred and heated at 80 ° C until obtaining d 'a homogeneous phase.
- the water and the surfactant of the aqueous phase are introduced into a second test tube in the proportions indicated in Table 1 1.
- the test tube is stirred and heated at 80 ° C until the obtaining a homogeneous phase.
- the aqueous phase is poured slowly into the fatty phase with vigorous stirring. Then the emulsion is mixed using a Turrax® type mixer at 9500 revolutions / minute for 30 seconds.
- the stability of the composition described in Table 11 is observed visually after centrifugation at T0, after centrifugation after 24 hours (T24h) and after 90 days (T2160h).
- the test tube contains 6.6 cm of emulsion, including 4.2 cm of fatty phase.
- a manual measurement of the phase shift is made, that is to say a measurement of the fatty phase released above the emulsion.
- the emulsion comprising the Marcol TM 52 oil has released more than the emulsion comprising Oil A.
- Example 4 preparation of a vaccine comprising the adjuvant composition of
- the vaccine is prepared according to the following protocol:
- Turrax® type mixer set at 10,000 rpm for 3 minutes at 25 ° C.
