Presentation of the center’s research focus/topic
CONTEXT AND BACKGROUND OF THE PROJECT
Infectious diseases such as pneumonia, hepatitis, and HIV are common, and often life threatening conditions. According to the
WHO, infectious diseases were the most common cause of death globally (25% of all deaths) in 2008.1) Since all age groups are
susceptible to infections, prevention or treatment of infectious diseases has the highest impact of all disease entities with regards to
increasing life span. The severity of infectious diseases depends on the immune system’s capability to maintain a balance between
fighting foreign infectious pathogens, and suppressing harmful self-destruction of the body’s own cells and tissue. This immune
balance can be improved by e.g. vaccines given in advance of exposure, but can also be impaired by either the infection itself (as for
HIV), or by an overshooting inflammatory process leading to self-destruction of host tissue. In order to develop new vaccines and
new drugs providing optimal immune balance, an understanding of the interplay between infectious organisms and the modulations of the immune system is needed.
PRESENTATION OF IDEA/RESEARCH TOPIC
We propose a Center of Experimental Immunomodulation under Aarhus University (AUCEI). The aim of this center is to accelerate the process of identifying and testing novel vaccines and immune modulatory molecules by taking our basic science discoveries
to immediate small scale clinical testing, and generating new basic science on the base of the clinical testing. The idea is to create a
feedback loop between basic science and clinical science in which both entities share and benefit from the newest knowledge, thus
resulting in faster and more efficient development of new therapies, and a deeper scientific understanding of the interplay between
pathogen and host immune response.
RELATION OF IDEA/RESEARCH TOPIC TO EXISTING RESEARCH
We have a longstanding record of initiating and conducting small-scale clinical trials in which novel immune modulatory molecules
and vaccines have been tested, and basic research questions have been solved in our laboratory. We have focused on prevention and
treatment of the most devastating chronic infectious disease, HIV, and the most severe acute infections such as septicemia, pneumonia and meningitis. The center will be a natural extension of these research topics. These diseases have also attracted a great
deal of attention from the international research community, but several questions remain to be answered. For example: we can
stop HIV infection from progressing to AIDS by treatment, but we cannot prevent HIV by vaccination, or cure HIV in an infected
person. However, new international research has identified Histone Deacetylase (HDAC) inhibitors as a novel class of drugs which
has the potential to stimulate HIV expression from latently infected resting cells, thereby reducing the viral reservoir (Archin et al.
AIDS 2009; Matalon et al. Molecular Med 2011). In addition, HDAC inhibitors have been suggested to possess immunomodulating activities independent of their action on HIV replication, which will also be analyzed at the level of signal transduction and
transcription factor activation. However, much remains to be investigated regarding the molecular mechanisms of the clinical and
immunological effects of HDAC inhibitors.
SOCIETAL AND SCIENTIFIC IMPORTANCE (SCHOLARLY RELEVANCE)
Scientifically, AUCEI’s goal is to be at the international front of experimental medicine within infectious diseases, and certain treatment resistant autoimmune conditions. We expect to identify and test novel immune modulatory molecules and pathways that may
have a profound therapeutic potential, and thus be of great innovative and scientific value. Society may potentially benefit from
AUCEI’s work in several ways including economic (new patents), educational (talent development), through improved health care
and quality of life (reduced cost of existing treatment, new prevention, and treatment options).
SUPPORTING MATERIALS AND METHODS
In addition to our Bio-safety level 3 facility,2) we are equipped with a modern laboratory, and use state of the art technology,
including Realtime qPCR (polymerase chain reaction), transcription factor analysis (TRANS-AM, phosho-flow reporter assays),
ELISA, multiplex bead analysis (Luminex), flow cytometry, cell sorting facility (FACS), siRNA technology, sequencing, and confocal microscopy. The proposed research idea requires use of all of these techniques but all methods can be established within the
existing laboratories and equipemnt. Further, in the project group are clinicians, post-docs, and PhD students with strong backgrounds in immunology, virology, cell biology, and clinical studies.

PERSPECTIVES FOR/IMPLICATIONS OF IDEA/RESEARCH QUESTION, AT PRESENT AND IN THE LONG TERM.
We propose that AUCEI has three main research topics during the pilot phase: New pharmacological interventions aimed at curing
HIV infection, new therapeutic options for recurrent fever syndromes (familial Mediterranean fever), and development of vaccines for immune compromised individuals. To explore these ideas we have proposed three specific research aims (detailed research
protocols can be requested):
I.
II.
III.
Identification and use of histone deacetylase inhibitors (HDACi) for the eradication of latent HIV infection.
Mechanisms and use of interleukin-1 beta (IL-1β) antagonists in recurrent fever syndromes (familiar Mediterranean fever)
Development and use of novel vaccines and Toll-like receptor (TLR) vaccine adjuvants
In the short term, focusing on these three niches will allow AUCEI to be at the forefront of the scientific field because these goals
are based on our existing expertise and knowledge. The prospect for the coming three years is to establish AUCEI as an international top level research center by strengthening our research network within AU, and with our international collaborators. The key
is to focus on novel research ideas (I-III) which are likely to generate new scientific discoveries with major potential for patenting
and further clinical development. This goal is achieved through collaborations with both academic and industrial partners. Besides
generating new patents, we expect to publish at least 15 papers in major international journals. In addition, new discoveries within
one area (I-III) will feed new knowledge into all clinical and basic science aspects of the other research areas.
In the long term (10 years) the proposed center will be an internationally renowned research institute. By focusing on research
questions that are of paramount scientific interest and health impact, AUCEI will be able to attract both internationally established
researchers as well as the most promising research talents. In addition, integrating basic science into clinical science and vice versa
can bridge the gap between AU basic science institutes and the clinical departments under Aarhus University Hospital. This will
strengthen the scientific network at AU, and pave the way for new research collaborations and scientific discoveries.

EXPECTED TALENT-DEVELOPMENT CONTRIBUTION.
Our goal is to recruit and educate at least 2 Post docs, 4 PhD students, and 6 pre-graduate students from Jan 2012 to Jan 2015. As
part of the AUCEI talent development we also expect to recruit foreign PhD students, and allow our own students and post docs
to engage in research stays with our collaborators.
FUTURE PLANS (ORGANISATIONAL, FINANCIAL, RESEARCH) IF EXPECTED RESULTS ARE ACHIEVED.
After the pilot phase, the center will be considered an upcoming international renowned institution for fast and efficient approach
in testing research questions related to immune balancing with high scientific standards. This will allow us to attract future financial
support from 3 potential sources: 1) As the center will be of international standard with international collaborators, research grants
will be obtained from international funds such as the Gates Foundation, NIH and EU, and 2) Revenue from new public-private
partnerships as offspring from our research activities (e.g. preclinical development and early phase testing of new potent HDACi
analogues 3) Revenue from trial site activities in phase 2b and 3 trial through collaborations with major pharmaceutical companies
(e.g. GSK, Pfizer, MSD).).
The proposed center has overlapping interests in immunology and immunomodulation with many of the other medical specialties
within Inflammatory Section such as Dermatology, Rheumatology, Oncology, and Hematology and the para-clinical specialties
such as Clinical Microbiology, Clinical Genetics and Clinical Immunology. It is therefore obvious to include these specialties in the
research during the later phases of research.

AUCEI will also use our international partners to establish new methods in assessing humoral and cellular immunity, as well as
identifying new signalling pathways and receptors. In addition, AUCEI will benefit from their expertise and access to novel immunological active compounds (e.g. HDACi through Topotarget/Italfarmaco/Novartis) and vaccines (e.g. therapeutic CTL-based HIV
vaccine through Klaus Überla).
LOCATION
The pre-existing laboratories and research facilities at the Department of Infectious Diseases will form the natural basis for the
majority of AUCEI activities. Certain immunological and virological laboratory analyses will be performed at our collaborator’s
research facilities at AU and internationally. In the long term, AUCEI may move to a new strategic location within the framework
of the inflammatory section under the New Aarhus University Hospital. However, with our previous contributions to biotech startups, we envision novel patents may form the basis for the development of a biotech company located in the Science Park at AU.
The market for prophylactic and therapeutic immune modulatory entities is increasing.
