Streptococcus pneumoniae stabilizes tumor necrosis factor alpha mRNA through a pathway dependent on p38 MAPK but independent of Toll-like receptors.

abstract：BACKGROUND:The need for rapid and accurate comparison of panels of adjuvanted vaccine formulations and subsequent rational down selection, presents several challenges for modern vaccine development. Here we describe a method which may enable vaccine and adjuvant developers to compare antigen/adjuvant combinations in a ...
