A lipoteichoic acid-related molecule OK-PSA is an active component of OK-432, a Streptococcus-derived anticancer immunotherapeutic agent. In the present study, we first examined the effect of OK-PSA(More)
The authors investigated the in vivo anti-tumor effect of intratumoral administration of bone marrow-derived dendritic cells (DCs) after chemotherapy using an oral fluoropyrimidine anti-cancer drug(More)
BACKGROUND OK-PSA, a lipoteichoic acid (LTA)-related molecule isolated from a streptococcal agent OK-432, enhances anti-tumor immunity as a potent inducer of Th1-type cytokines. Recently, we obtained(More)
We have previously isolated a lipoteichoic acid (LTA)-related molecule (OK-PSA) from OK-432, a streptococcal agent, by affinity chromatography on a CNBr-activated Sepharose 4B bound TS-2 monoclonal(More)
