Description
ISCOM vaccines induce a balanced Th1/Th2 response and cytotoxic T lymphocytes. The adjuvant component, ISCOM-Matrix, consists of purified saponin fractions, cholesterol and phospholipids. The mode of action for the ISCOM-Matrix is known to some extent but still we lack knowledge of important segments in initiation of the immune response. The study was performed to analyze the early transcriptional responses to the ISCOM-Matrix alone, without the use of co-administered antigen. Matrix M (AbISCO 100) was given as intramuscular injection and after 24 hours the pigs was sacrificed for gene expression analysis, performed for the injection site and the draining lymph node.
