Combinatorial chemistry has become an important aspect of medicinal research due to its flexibility and the ability to produce large numbers of potential therapeutic agents. Once compounds are made, they must be screened to determine if there is any biological activity. This research project focused on developing a screening method for chemical agents produced by a graduate student in the chemistry department at Wright State University. After an acceptable screening method was found, the goal of the project was to determine if compounds produced had either antibacterial activity, antifungal activity, or both. Seven compounds exhibited biological activity. Two of these …

Over the past two decades, much research has been done in the field of human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS). However, many of the aspects of pathogenesis of HIV infection and its persistence in the body, despite treatment, remain a mystery. Recent evidence suggests that HIV positive patients develop eosinophilia, especially in the later stages of infection and AIDS. Eosinophils are CD4 positive cells that have the potential to be infected by HIV. Studies have shown that an eosinophilic cell line, AML14.3D10, can be productively infected with a T-cell tropic, CXCR4-using (X4) strain of HIV-1. In this …

Escherichia coli (E. coli) is a gram negative bacterium commonly found as a commensal in the intestinal tract of humans and other warm blooded animals. The commensal strains of E. coli are non-pathogenic and do not cause an infection in the host. However, some strains of E. coli are pathogenic and can cause several diseases in humans that include neonatal meningitis, intestinal infections and urinary tract infections. Almost 80-85% of the uncomplicated urinary tract infections are caused by uropathogenic E. coli. Our project involved the characterization of 12 strains of E. coli, isolated from humans in health and disease. These …

Natural Killer T cells (NKT cells) are a unique subset of lymphocytes that express natural killer (NK) and T cell receptors (TCR). The NKT cell population includes four separate subclasses. This paper will focus on Category I NKT cells which possess a canonical TCR receptor (Va14Ja281) that recognizes only hydrophobic antigens presented by CD1d molecules. These cells are believed to play an important regulatory role in immunity. A variety of disease conditions, including cancer, infections and Type I diabetes, are controlled by NKT cells. NKT cells are also capable of secreting large quantities of cytokines, namely interleukin-4 (IL-4) and interferon-gamma …
