Our Coley’s Toxins Therapy touches all major facets of immunology and holds enormous clinical promise. Scores of clinical studies are aiming the immuno-stimulating power of adjuvants at tumors. Scientists are also developing approaches that could target a broader range of infectious agents. Studies have shown that the production of dendritic cells, contributes to fever, a process that the body creates as a potential immune reaction, that tries to eradicate diseased cells. This awareness is inspiring dendritic-cell-based medical therapies that treat auto-immune and degenerative disorders – such as the Coley’s Toxin.
There are several names for Coley’s Toxins or Coley’s Vaccine. The reason may rest in the difficulty of classifying such a substance under the view of the established medicine: Coley’s vaccine is not a vaccine in the usual sense, namely because a vaccine is used to prevent an infection. This vaccine triggers an “immune-like” response, i.e. Coley’s behaves like an ordinary vaccine; it induces an immune response, in this case against the cancer cells. In this sense, it predates any current attempts to develop cancer vaccines or toxins. The term toxin is applied as Coley’s Toxins contain both endotoxins and exotoxins. Learn More
Dendritic cells: A robust fever, which occurs in response to Coley’s fluid, generates inflammatory factors with co-stimulatory activity, which activates resting dendritic cells (DC), leading to the activation of anergic T-cells, maybe accomplished by a second process, where a possible physical damage of cancer cells leads to a sudden supply of cancer antigens to DC.
Tumor Necrosis Factor and Interleukin: One of the agents in Coley’s Toxins that is thought to be biologically active is a lipopolysaccharide which causes fever. The resulting fever from the lipopolysaccharide is thought to increase lymphocyte activity and boosts tumor necrosis factor (TNF). Tsung and Norton in Surgical Oncology (SO), reported that the active agent was thought to be interleukin-12, rather than TNF. Learn More
Streptokinase: Another hypothesis argues that streptokinase (produced by bacteria of type “streptococcus” together with plasminogen from the patient) is the active agent of Coley’s toxins. This hypothesis is supported by the fact that streptokinase has been associated with successful treatment of thromboangiitis obliterans. Learn More
Anti-angiogenesis: In addition to the mechanisms above, Coley’s toxins might be anti-angiogenic; suppressing the formation of new blood vessels which are vital to the growth of tumors. However, angiogenesis is not biochemically caused by itself, but externally triggered. Learn More
PAMP: As recently as 2008, an immunological explanation binding together immunological data with findings about spontaneous regression and epidemiological data indicating a lowered risk to develop cancer later after common infections, has been published. According to this hypothesis, pathogenic substances produced by bacteria, viruses, infectious fungi and other pathogens, but not human tissue, called pathogen associated molecular pattern (PAMP) lead to activation and maturation of tumor-antigen loaded dendritic cells. One PAMP thought that plays a major role is the unmethylated CpG motif found in bacterial DNA. The CpG motif is recognized by tools like receptor 9 (TLR9) and can induce a strong TH1 response.
