(second version, the first one may be walking through the cyberspace...)
I performed a human PBL culture (one hundred, actually).This culture was
performed in order to test immuno activity of a peptide called Pa. After
culturing (RPMIc, 5% FCS, 37C, %5 CO2, 24h), I measured cytokine releasing
Results: IL-2, IFNg: releasing. IL-4, TNFa, IL1a, IL1b: no releasing.
I mean, this results could suggest Pa is presented and induce cytokine
releasing by Th1 Tcell. But monocytes, the only APC available into human
PBLs, appear not to be activated.
I thought APC activation (in that cytokine releasing) and presentation were
always together. But seeing my results my idea seems to be wrong.
Could anyone tell me any opinion?
