Oda et al., Life Sci 1999
:
Stimulation of PPD-specific and Der f-specific T cell lines with relevant antigens resulted in production of mostly interferon (IFN)-gamma and of interleukin (IL)-4 and IL-5, respectively
Kurtzhals et al., J Immunol Methods 1992
:
PPD did not increase IL-4 production above the background level, although the majority of PPD stimulated PBMC proliferated and produced interferon-gamma (IFN-gamma) in cultures without ionomycin and PMA
Finan et al., PloS one 2008
:
IFN-gamma, interleukin (IL)-5 and IL-13 responses to purified protein derivative (PPD) , killed Mycobacterium tuberculosis ( KMTB ), M. tuberculosis short term culture filtrate ( STCF ) and M. bovis BCG antigen 85 complex ( Ag85 ) were measured in a whole blood assay two months after vaccination
