Systemic lupus erythematosus (SLE) is a multiorgan autoimmune disease affecting 40-50/100,000 Americans. Although most of the research on pathogenic antibodies focuses on antigenic specificity, there is increasing evidence that specific immunoglobulin idiotypes may mediate lupus nephritis independent of autoantigen specificity. In previous work, our(More)
The acceleration of nephritis in SNF(1) mice by CD4(+) T-cell clones reactive with a nephritogenic idiotype, Id(LN)F(1) [1], as well as the ability of anti-Id(LN)F(1) antisera to down-regulate the production of Id(LN)F(+)(1) immunoglobulin (Ig) in vivo and delay nephritis [2], suggests that dysregulation of this idiotype may contribute to the development of(More)
Opportunistic infections (OIs) during the course of non-clinical toxicity studies can serve as a clinical indicator of immunosuppression. In monkeys, severity may be magnified since the possibility for fecal-oral and cage-to-cage transmission of bacteria exists, reserve capacity is low, and clinical signs of infection are not easily detected until the(More)
A multinational pharmaceutical and biotechnology company survey was conducted to gain a better understanding of the use and value of the tissue cross-reactivity (TCR) assay in the development of biotherapeutic molecules. The majority of the molecules did not use TCR data as the only basis for determining species selection for toxicity studies (73%). For 95%(More)
Functional innate immune assessments, including phagocytosis and respiratory burst, are at the forefront of immunotoxicology evaluation in pre-clinical animal species. Although in the clinic and in academic science, phagocytosis, and respiratory burst assessments have been reported for over two decades, the implementation of phagocytosis and respiratory(More)
Non-human primates (NHP) are used to best understand and address pharmacology and toxicology obligations for human patients with highest and/or unmet need. In order to ensure the most appropriate care and use of NHP, it is important to understand the normal micro flora and fauna of NHP and ensure their utmost health to generate the most valuable and(More)
