On the other hand, when immunizing HLA transgenic mice i.p. with peptides combined with the recently developed cationic liposome adjuvant CAF09 (15), high levels of IFNγ was produced by CD8 T cells specific for influenza peptides PA(282–290), PB1(410–418) as well as M(58–66). The gene discussed is IFNG; the disease is influenza.
