Adjuvant activity of mycobacterial fractions: adjuvant activity of synthetic N-acetylmuramyl-dipeptide and the related compounds.
Immunological activity of synthetic cell wall peptidoglycan subunits was examined in guinea pigs and mice. It was concluded that the minimal adjuvant-active subunit of cell wall peptidoglycan for the induction of delayed-type hypersensitivity to monoazobenzenearsonate-N-acetyl-L-tyrosine and for circulating-antibody formation to bacterial alpha-amylase and the thymus-independent antigen DNP-Fic...
متن کاملAdjuvant activity of synthetic 6-O-"mycoloyl"-N-acetylmuramyl-L-alanyl-D-isoglutamine and related compounds.
Adjuvant and antitumor activities of synthetic 6-O-"mycoloyl"-N-acetylmuramyl-L-alanyl-D-isoglutamine were examined. All the synthetic 6-O-corynomycoloyl-, 6-O-mocardomycoloyl-, and 6-O-mycoloyl-N-acetylmuramyl-L-alanyl-D-isoglutamine were active as adjuvants for cell-mediated immune responses. However, 6-O-mycoloyl-N-acetylmuramyl-L-alanyl-D-isoglutamine was less active as an adjuvant on circu...
متن کاملKinetics of the humoral and cellular immune response of guinea pigs after injection of the synthetic adjuvant N-acetylmuramyl L-alanyl-D-isoglutamine: comparison with Freund complete adjuvant.
We studied the time course of humoral and cellular immunity of guinea pigs injected with the synthetic adjuvant N-acetylmuramyl L-alanyl-D-isoglutamine (MDP Pasteur, 10 microgram) in Freund incomplete adjuvant; the kinetics were compared with those obtained with Freund complete adjuvant (50 microgram of whole Mycobacterium butyricum). The antibody response to ovalbumin was faster and higher wit...
متن کاملAnticoagulant activity of synthetic hirudin peptides.
Synthetic peptides based on the COOH-terminal 21 residues of hirudin were prepared in order to 1) evaluate the role of this segment in hirudin action toward thrombin, 2) define the shortest peptide derivative with anticoagulant activity, and 3) investigate the role of tyrosine sulfation in the peptides' inhibitory activities. A hirudin derivative of 20 amino acids, Hir45-64 (derived from residu...
متن کاملMotogenic activity of IGD-containing synthetic peptides.
Although the IGD amino acid motif (iso-gly-asp) is a highly conserved feature of the fibronectin type I module, no biological activity has as yet been ascribed to it. We have previously reported that the gelatin-binding domain of fibronectin stimulates the migration of human skin fibroblasts into native, but not denatured, type I collagen substrata. Two IGD-containing type I modules are present...
