N-acetylmuramyl-L-alanyl-D-isoglutamine or MDP is a synthetic immunoadjuvant capable of inducing a febrile response in the rabbit and of eliciting production of endogenous pyrogen (EP) in vivo and in vitro. It was also shown to stimulate in vitro lymphocyte activating factor (LAF) release. After conjugation to a synthetic carrier, the pyrogenic effect of MDP is strongly enhanced. Recently, adjuvant active derivatives of MDP devoid of pyrogenicity such as MDP(Gln)-OnBu (AcMur-L-Ala-D-Gln-alpha-nbutyl ester) have become available. In the present study, their stimulating properties on rabbit peritoneal exudate cells or human peripheral blood mononuclear cells were simultaneously evaluated by testing lymphocyte activating property and pyrogenic effect of the culture supernatant. In both types of cell cultures, whereas MDP elicited dual effects, the nonpyrogenic analog MDP(Gln)-OnBu produced LAF without detectable pyrogenicity even when a very sensitive assay (intracerebroventricular administration) was used. In contrast, conjugated MDP was capable of inducing the production of endogenous pyrogen in rabbit cell cultures with no or little LAF release. These results argue against the possibility that a single factor is responsible for both LAF and EP activities.
