title: Post challenging serum cytokine profile (Th1 & Th2) in the vaccinated mice (Balb/C) with a new formulation of Leishmania major antigen.
abstract: OBJECTIVE
  The aim of this study was to carry out experiments further to our previous new formulation to modify the Leishmania major antigen that had satisfactory results previously.
  
  
  METHODS
  In this study we made a preliminary, new vaccine with the same methodology and selected two injection doses (100&200 μg/o.1 mL), three injection Groups: Leishmania plus BCG (LB), Leishmania plus new adjuvant (Teucrium Polium) [LT], Leishmania plus BCG and Teucrium Polium (LBT), and one susceptible mouse Group (Balb/c) and measure two types of cytokines: Th1 (IFN-γ, IL-12) and Th2 (IL-4, IL-10) We prepared crude antigen combinations by five different methods using antigens from L. major parasites. Phase I was done in the animal model. In our study, Leishmania antigen was examined both with BCG and the new adjuvant (TP) in three Groups in two injection doses (100.200 μg/1 mL) and Balb/c mice.
  
  
  RESULTS
  Our results showed that in three injection Groups (LB, LT and LBT) that received each or both BCG and TP as adjutant with injection doses of 100 and 200 μg/1 mL with two booster doses: the LBT Group had the lowest IFNγ and highest IL-12 value, LT and LB Groups have equal IL-12, but LB have more IFNγ and IL-10 but less than IL-4 in the LT Group.
  
  
  CONCLUSIONS
  In this study, the LBT Group has statistical differences regarding IL-12 and IL-10 from the other Groups.
