The Functions Of The Cid And Lrg Operons In S. Aureus Programmed Cell Death, Xinyan Zhang
The Functions Of The Cid And Lrg Operons In S. Aureus Programmed Cell Death, Xinyan Zhang
Theses & Dissertations
Staphylococcus aureus cid/lrg operons regulate the formation of S.aureus biofilm formation and programmed cell death based on previous in vivo work done in Dr. Bayles's lab. cid operon, which encodes CidA/CidB/CidC proteins, has been shown to be an effector in leading to the lysis and death of the S.aureus; While lrg operon, encoding LrgA and LrgB proteins, is an inhibitor of the lysis and death. Recent studies suggest that CidA behaves like holin proteins from bacterial phage, by increasing the murein hydrolysis activity under aerobic culturing conditions. LrgA, together with LrgB, appears to inhibit this function. …

The T helper type 2 (Th2) cell product interleukin 10 (IL-10) inhibits the proliferation and function of Th1 lymphocytes and macrophages (M phi). The nonobese diabetic mouse strain (NOD/Shi) develops a M phi and T cell-dependent autoimmune diabetes that closely resembles human insulin-dependent diabetes mellitus (IDDM). The objective of the present study was to explore the consequences of localized production of IL-10 on diabetes development in NOD/Shi mice. Surprisingly, local production of IL-10 accelerated the onset and increased the prevalence of diabetes, since diabetes developed at 5-10 wk of age in 92% of IL-10 positive I-A beta g7/g7, I-E- mice …
