Plasmodium Impairs Antibacterial Innate Immunity To Systemic Infections In Part Through Hemozoin-Bound Bioactive Molecules., Christopher Lynn Harding
Plasmodium Impairs Antibacterial Innate Immunity To Systemic Infections In Part Through Hemozoin-Bound Bioactive Molecules., Christopher Lynn Harding
Electronic Theses and Dissertations
Despite efforts to decrease the global health burden of malaria, infections with Plasmodium species continue to cause over 200 million episodes of malaria each year which resulted in 405,000 deaths in 2018 [1]. One complication of malaria is increased susceptibility to invasive bacterial infections. Plasmodium infections impair host immunity to non-Typhoid Salmonella (NTS) through activities of heme oxygenase I (HO-I) )-induced release of immature granulocytes and myeloid cell-derived IL-10. Yet, it is not known if these mechanisms are specific to NTS. We show here, that Plasmodium yoelii 17XNL (Py) infected mice had impaired clearance of systemic Listeria monocytogenes (Lm) during …
Mutational Analysis And Domain Characterization Of The Apolipoprotein L-1 Ion Channel, Charles M. Schaub
Mutational Analysis And Domain Characterization Of The Apolipoprotein L-1 Ion Channel, Charles M. Schaub
Dissertations, Theses, and Capstone Projects
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. …
Assessment Of The Immune Response To Posthodiplostomum Minimum Infection In Bluegills, Olamide S. Olayinka
Assessment Of The Immune Response To Posthodiplostomum Minimum Infection In Bluegills, Olamide S. Olayinka
Masters Theses
Bluegills (Lepomis macrochirus) are common intermediate hosts for white grub (Posthodiplostomum minimum). They tolerate heavy infections with minimal effect on condition and continue to accumulate metacercariae as they age. This suggests that any immune response to this parasite might not be effective. This study was conducted to better understand the immune mechanisms underlying P. minimum infection in bluegills.
Infected organs (liver, kidney, and heart) were examined histologically, and serum from infected fish was tested for antibodies to white grub. Juvenile flukes were recovered from isolated metacercarial cysts. Polyclonal antibodies were produced in mice against white grub …
