Hematopoietic stem and progenitor cell (HSPC) compartments are altered to direct immune responses to infection. Their roles during immunization are not well-described. To elucidate mechanisms for waning immunity following immunization with acellular vaccines (ACVs) against Bordetella pertussis (Bp), we tested the hypothesis that immunization with Bp ACVs and whole cell vaccines (WCVs) differ in directing the HSPC characteristics and immune cell development patterns that ultimately contribute to the types and quantities of cells produced to fight infection. Our data demonstrate that compared to control and ACV-immunized CD-1 mice, immunization with an efficacious WCV drives expansion of hematopoietic multipotent progenitor cells …

Adherence-Associated Properties Of Moraxella Bovis , Susan Herkender Jackman

Susan H. Jackman

The research involved the study of adherence-associated properties of Moraxella bovis, the primary etiologic agent of infectious bovine keratoconjunctivitis (IBK). M. bovis 118F, an isolate from a naturally occurring infection of IBK, and a UV-derived mutant, 118F/4-2, were utilized;Negative stain preparations demonstrated that 118F readily expressed pili when grown on bovine blood agar while 118F/4-2 was essentially nonpiliated. The average diameter of pili was 5.5 nm. Hemagglutinating ability was not inhibited by a variety of sugars including D-mannose and correlated with the degree of piliation;Surface hydrophobicity was evaluated using hydrophobic interaction chromatography. M. bovis 118F readily adsorbed to the hydrophobic …

IMMUNOLOGICAL MECHANISMS OF EXTRACORPOREAL PHOTOPHERESIS IN CUTANEOUS T CELL LYMPHOMA AND GRAFT VERSUS HOST DISEASE

Supervisory Professor: Madeleine Duvic, M.D.

Extracorporeal photopheresis (ECP) is an effective, low-risk immunomodulating therapy for leukemic cutaneous T cell lymphoma (L-CTCL) and graft versus host disease (GVHD), but whether the mechanism(s) of action in these two diseases is (are) identical or different is unclear. To determine the effects of ECP in vivo, we studied regulatory T cells (T-regs), cytotoxic T lymphocytes (CTLs), and dendritic cells (DCs) by immunofluorescence flow cytometry in 18 L-CTCL and 11 GVHD patients before …

Dr. Fauci, Director of the National Institute of Allergy and Infectious Diseases (NIAID) of the National Institute of Health (NIH), also serves as the Associate Director of the NIH for research on the acquired immunodeficiency syndrome (AIDS) and as Director of the NIH Office of AIDS Research. A native of Brooklyn, New York, Dr. Fauci received his M.D. degree from Cornell University Medical College in 1966. After completing an internship at Cornell Medical Center in New York City, he began his work at the NIH as …
