Differential regulation of Ia expression and antigen presentation by listeriolysin-producing versus non-producing strains of Listeria monocytogenes

Autor: M. L. Proctor, Christopher Y. Lu, S. C. Sicher, Miguel A. Vazquez, J. C. Crowley

Publikováno v: Journal of Leukocyte Biology. 59:683-690

listeria monocytogenes is an intracellular bacterial pathogen. A single gene product, listeriolysin (LLO), is critical for the induction of protective immunity. We now show that listeria that produce functional LLO augment Ia expression by macrophage

Transcription of the murine iNOS gene is inhibited by docosahexaenoic acid, a major constituent of fetal and neonatal sera as well as fish oils

Macrophage activation is deficient in the fetus and neonate when the serum concentrations of docosahexaenoic acid (DHA) are 150 microM, or 10-50-fold higher than in the adult. We now show that DHA inhibits production of nitric oxide (NO) by macrophag

Augmentation or inhibition of IFN-gamma-induced MHC class II expression by lipopolysaccharides. The roles of TNF-alpha and nitric oxide, and the importance of the sequence of signaling

Publikováno v: The Journal of Immunology. 155:5826-5834

MHC class II expression on macrophages is one determinant of Ag presentation and the vigor of CD4+ T cell immunity. We show that LPS may either inhibit or augment IFN-gamma-induced MHC class II on macrophages depending on the sequence of the IFN-gamm

Docosahexaenoic acid, a major constituent of fetal serum and fish oil diets, inhibits IFN gamma-induced Ia-expression by murine macrophages in vitro

Autor: T A Khair-el-Din, S C Sicher, M A Vazquez, W J Wright, C Y Lu

Publikováno v: The Journal of Immunology. 154:1296-1306

Decreased Ia expression by macrophages may account for the increased susceptibility of fetuses and neonates to infection. We chose to investigate the role of docosahexaenoic acid (DHA), an omega-3 fatty acid, on Ia expression in vitro, because neonat

Inhibition of macrophage Ia expression by nitric oxide

Autor: S C Sicher, M A Vazquez, C Y Lu

Publikováno v: The Journal of Immunology. 153:1293-1300

Bacterial LPS inhibits the expression of Ia by macrophages stimulated by IFN-gamma. We now present the following observations that suggest a causal relationship between nitric oxide (NO) and this inhibition of Ia expression: 1) NO production precedes

Nitric oxide inhibits INFgamma-induced increases in CIITA mRNA abundance and activation of CIITA dependent genes--class II MHC, Ii and H-2M. Class II TransActivator

Autor: M L, Kielar, S C, Sicher, J G, Penfield, D R, Jeyarajah, C Y, Lu

Publikováno v: Inflammation. 24(5)

Nitric oxide (NO) has been recently implicated as a powerful inhibitor of immune responses during allograft rejection, and some autoimmune and infectious diseases. We previously showed that one potential regulatory effect of NO is inhibition of IFNga
