Bacterial stimulation may serve to control atopic disorders such as atopic dermatitis (AD) through inducement of Th1 cell-mediated immune response. The lipoteichoic acid (LTA)-related molecule (okLTA) from streptococcal preparation, OK-432, has been

We examined the role of nitric oxide (NO) induced by OK-432, a streptococcal immunotherapeutic agent, in anti-tumor effects of the OK-432 by in vitro and in vivo experiments using an NO synthase inhibitor, N-monomethyl-l-arginine acetate (NMA). The i

OK-432 is a Streptococcus-derived immunotherapeutic agent for malignancies. Our group has tried to identify the effective components of OK-432 and has succeeded in isolating a lipoteichoic acid-related preparation designated as OK-PSA, which is a str

It has previously been reported by our group that Toll-like receptor (TLR) 4 is involved in anticancer immunity induced by OK-432, a Streptococcus-derived immunotherapeutic agent. However the detailed mechanism of the OK-432-induced immune response v

We investigated in the current study the effect of TX-1877, a bifunctional hypoxic cell radiosensitizer, in augmenting anticancer host response. In the syngeneic squamous cell carcinoma-bearing mouse model, a single administration of TX-1877 signific

A 55-kDa protein named AILb-A, isolated from the seed extract of Aeginetia indica L., a parasitic plant, induces a Th1-type T-cell response and elicits a marked antitumor effect in tumor-bearing mice. In the present study, we examined the role of Tol
