Increased prostaglandin production is implicated in the pathogenesis of glomerular disease. With this consideration, we examined the combined effects of reactive oxygen species and platelet-derived growth factor (PDGF), which might initiate glomerular dysfunction, on arachidonic acid release and cytosolic phospholipase A(2) (cPLA(2)) activation in rat(More)
Genetic control of immune response in man was investigated with the system of antigen-specific T cell proliferation in vitro against streptococcal cell wall (SCW) antigen. Family analysis by Morton's maximum likelihood scoring method revealed that the low response to SCW antigen was controlled by a single dominant gene. Furthermore, this gene was shown to(More)
We previously reported that zymosan-stimulated, protein kinase C (PKC)-dependent arachidonic acid liberation occurs with association of Ca2+-independent phospholipase A2 (iPLA2) with the membranes of macrophage-like P388D1 cells. In the present study, the possible involvement of PKC isoforms (alpha, beta, delta, and epsilon) on the increase in iPLA2 was(More)
This paper is concerned with the adjuvant activity in stimulatory immunoglobulin E production against ovalbumin (OA) by bacterial cell walls, cell wall peptidoglycan (PG), and their PG fragments and synthetic N-acetylmuramyl (MurNAc) dipeptides in A/J mice. A PG isolated from Streptococcus pyogenes, PG subunit polymer and dimer obtained from Staphylococcus(More)
