The Increase Of Cd4+Cd25+ T Cells In The Peripheral Blood Of Pigs Persistently Infected With Porcine Reproductive And Respiratory Syndrome Virus, Jingwen Zeng, Danting He, Xin Guo, Xinna Ge, Hanchun Yang

Turkish Journal of Veterinary & Animal Sciences

Regulatory T lymphocytes (T-regs) may be involved in suppressing the host's immunity, which is important for viral clearance, and may therefore contribute to persistent viral infection. However, nothing is known regarding the situation of porcine T-regs during persistent infection with porcine reproductive and respiratory syndrome virus (PRRSV). This study, which used flow cytometry and real-time PCR, determined that the frequencies of CD4+CD25+ T-cells and porcine Forkhead/winged helix transcription factor (FoxP3) mRNA levels in peripheral blood significantly increased during PRRSV persistence, indicating that CD4+CD25+ T-regs might play an important role in PRRSV persistent infection. This study contributes to a better understanding …

The Role Of Inflammatory Molecules In Hypertension, Jeffrey Paul Cardinale Jan 2011

The Role Of Inflammatory Molecules In Hypertension, Jeffrey Paul Cardinale

LSU Doctoral Dissertations

Hypertension is a serious condition with high morbidity and mortality rates, as well as a major predisposing factor for multiple cardiovascular and renal diseases. Angiotensin II (Ang II) of the renin-angiotensin system (RAS) plays a pivotal role in propagating the hypertensive response. Moreover, hypertension is considered a chronic low-grade inflammatory condition that intimately involves the actions of proinflammatory cytokines (PICs) such as tumor necrosis factor-alpha (TNF). Recent evidence highlights the role that inflammation, specifically TNF, plays in hypertension and in regulating the RAS, but the understanding as to how inflammation is regulated following Ang II or TNF activation, as well …


Characterization Of Spiroplasma Mirum And Its Role In Transmissible Spongiform Encephalopathies, Hilari Maree French Jan 2011

Characterization Of Spiroplasma Mirum And Its Role In Transmissible Spongiform Encephalopathies, Hilari Maree French

LSU Doctoral Dissertations

There are many contradictory reports in the literature involving the culture of Spiroplasma mirum, its resistance to disinfectants and antibiotics, and its potential role in Transmissible Spongiform Encephalopathies (TSEs). These contradictions led to an interest in a possible link between spiroplasma and TSEs and the development of a research plan to elucidate this connection. It was hypothesized that Spiroplasma was associated with a neurodegenerative disease such as TSE. In this work we further characterized S. mirum laboratory strains and continued to evaluate the possible correlations they have with TSE infections and the prion. To optimize recovery of S. mirum from …


Arginine Metabolism In The Edwardsiella Ictaluri- Channel Catfish Macrophage Dynamic, Wes Arend Baumgartner Jan 2011

Arginine Metabolism In The Edwardsiella Ictaluri- Channel Catfish Macrophage Dynamic, Wes Arend Baumgartner

LSU Doctoral Dissertations

Edwardsiella ictaluri encodes a urease operon and an arginine decarboxylase (AdiA) that are required for virulence in head kidney derived macrophages (HKDM). The urease produces ammonia in amounts sufficient to alter environmental pH from acid to neutral. A hypothetical model was proposed, involving arginine metabolism in E. ictaluri infected HKDM, focusing on bacterial urease, AdiA, a second arginine decarboxylase (SpeA), and agmatinase (SpeB). Using fluorescence based ratiometric pH determination of E. ictaluri in live HKDM, it was shown that E. ictaluri modulates HKDM phagosome pH to above six. Urease and AdiA mutants failed to up-regulate vacuole pH, while vacuole pH …
