Most of wax D (peptidoglycolipid) used here appeared to be ineffective for production of arthritis when given in a water-in-oil emulsion, while the same wax D in squalane was very effective for production of arthritis. Arlacel A as an emulsifier appeared to suppress the arthritogenicity of wax D in squalane, probably through some interaction with the arthritogenic portion of wax D. Poly 1:C seemed to remarkably enhance the arthritogenicity of wax D, even in water-in-oil emulsion. Acetylated wax D and cord factor (trehalose-dimycolate) were much less effective than poly 1:C. Delayed skin hypersensitivity to PPD, peptidoglycan and poly 1:C was also markedly affected by oil composition. However, there was no correlation between these delayed hypersensitivities and development of arthritis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
