In bacterial vaccines, the antigen causes the same
immunopathology as the disease itself.

They found that IL - 27 levels in infected lungs follow, with some delay, the level of virus: they peak
as viral levels are starting to decline and come down when
immunopathology has resolved.
Fahmy, who worked
as a chemical engineer at DuPont for 5 years before doing a Ph.D. in
immunopathology, had just explained the complex relationship between the lymphatic system and the circulatory system when a reporter interrupted him.
The concern for an occurrence of lung
immunopathology on challenge of mice vaccinated with an inactivated virus vaccine,
as reported by Haagmans, et al. for ferrets and nonhuman primates, was seen by us after challenge of mice vaccinated with a SARS VLP vaccine [20].
As indicated, two reports attributed the
immunopathology to presence of the N protein in the vaccine; however, we found the same immunopathologic reaction in animals given S protein vaccine only, although it appeared to be of lesser intensity.
Those challenged animals exhibited infection similar to unvaccinated animals
as well
as Th2 - type
immunopathology.
As indicated, strong animal model evidence indicates expression of the N protein by SARS - CoV vector vaccines can induce sensitization leading to a Th2 — type
immunopathology with infection.
To be certain the Th2 type
immunopathology was elicited by the S protein vaccine in our studies and in hopes a greater immune response would result from higher dosages of the vaccine and induce greater protection against infection
as well
as reduce or prevent the
immunopathology, our experiment 2 used up to 9 µg of the S protein for immunization.
Dr. Sanfilippo received his BS and MS degrees in physics from Penn, his MD and PhD in immunology
as an NIH Medical Scientist Training Program Fellow at Duke, and Pathology residency training at Duke, with Boards in Anatomic and Clinical Pathology, and
Immunopathology.
At Duke he also served
as Director of the Duke - VAMC Immunogenetics - Transplantation Laboratory, Director of the Duke
Immunopathology Lab, and chief of the Renal and Transplant Pathology services.
The Sette lab's approach uses epitopes
as specific probes to define the immune signatures associated with productive / protective immunity versus deficient immunity /
immunopathology.
