Definition

A recombinant 19 kDa protein derived from the Apicomplexa protozoan Eimeria with potential immunostimulating and antitumor activities. Upon administration, innate immunostimulator rBBX-01 activates dendritic cells (DCs), stimulates the Toll-like receptor 11 (TLR-11)-mediated release of interleukin-12 (Il-12) from DCs, and induces a T-helper 1 (Th1) type immune response, which may induce an immune response against tumor cells. Infection with Eimeria, a coccidian commonly infecting the intestine, may be negatively correlated with tumorigenesis.
