The Investigation Of Surface Structures On Various Pathogens And Their Interactions With The Human Immune System, Carmen M. Villalobos
The Investigation Of Surface Structures On Various Pathogens And Their Interactions With The Human Immune System, Carmen M. Villalobos
Biomedical Engineering ETDs
The cell surface is the first interface the host immune system encounters and
its investigation has led to a better understanding of cellular biology and types of
pathways that pathogens target in a host cell. The cell surface has evolved to include
many functions such as manipulation of the cytoskeleton, cell signaling, membrane
trafficking, adhesion, and integration into host tissue. The pathogens of interest are
the pathogenic fungus, Candida albicans, and the parasite, Giardia lamblia and we
investigate the consequences of drug treatments on the cell surface, leading to
promising new targets.

The human innate immunity factor Apolipoprotein L-1 (APOL1) protects against Trypanosoma brucei brucei infection. Recent studies have shown recombinant APOL1 (rAPOL1) inserts into planar lipid bilayers at an acidic pH 5.6 and forms a cation-selective channel, which opens upon subsequent neutralization, pH 7.2. This corresponds with the pH changes APOL1 would encounter during endosome recycling, suggesting that APOL1 forms a pH-gated ion channel in the plasma membrane of the parasite, leading to uncontrolled ion flux and osmotic imbalance. However, structural and domain characteristics of the APOL1 channel are poorly understood, despite potential similarities to diphtheria and colicin toxins. Utilizing E. …
