Figure 6. Flow cytometric analysis of unfractionated splenocytes to characterize multifunctional cellular immune responses.
Immune responses to Alhydrogel-absorbed EP-1043 protein and the peptide pool in CFA/IFA were characterized using ICS and flow cytometry to assess the number and phenotype of multifunctional T-lymphocytes with respect to cytokine production. The production of IFN-γ and IL-2 by CD4+ T-lymphocytes is shown in panels A and C, respectively. Data indicating a lack of IL-4 and IL-5 production is shown in panel C. Proliferation of CD4+ T-lymphocytes following epitope peptide stimulation is shown in panel D.
