Research interests

 

 

Animal models for infectious diseases, allergy and tumorbiology

Mucosal vaccines for prophylaxis and therapy of allergy, infectious diseases and cancer (breast cancer, melanoma)

New antigen delivery systems and adjuvants

Immunological tolerance as treatment strategy against immunological disorders

 

Ongoing research programs

 

Animal models:

 

Allergy (mono and polysensitized animals)

Toxoplasma gondii infection

Breast cancer and melanoma

 

 

Mucosal vaccination and delivery of vaccines:

 

Lactic acid bacteria as expression systems and 

vaccine vehicles for:

 

Allergens, hypoallergenic variants, chimeric molecules

Protozoal antigens: surface antigen of T. gondii (SAG1)

Tumor antigens: Her-2/neu peptides, mimotopes of melanoma antigens (HWW)

 

Mucosal tolerance induction:

 

Mucosal tolerance induction as treatment concept 

(prophylaxis and therapy) against  allergic

monosensitization: studies on mechanisms of  

tolerance

Tolerance induction against allergic

polysensitization: use of hybrid peptides or chimeric 

molecules

 

Development of a peptide based vaccine against breast cancer: from bench to clinic

 

Her-2/neu transgenic mouse model:

Immunization with peptides derived from extracellular 

domain of Her-2/neu coupled to immunopotentiating 

reconstituted influenza virosomes

 

Phase I/II study in humans: cooperation with 

Internal Medicine, MUW, BLS and Pevion Biotech.

 

 

 

 

 

Characterization of humoral and cellular immune responses after vaccination

 

Evaluation of antibody titers 10 years after 

vaccination with Hep. A vaccine

Measurement of cellular immune responses (T cell 

proliferation, cytokine production pattern)

Characterization of T cell populations (cell surface 

marker expression)

HAV-receptor expression profile (mRNA) on T cells

 

 

 

Newly initiated projects

 

 

Toxoplasma gondii infection:

 

Inverse correlation between infections such as hepatitis A

or toxoplasmosis and prevalence of atopy („hygiene  

hypothesis“): Influence of a toxoplasma gondii infection on

allergic sensitization tested in a mouse model.

 

Immunological responses during the course of

infection (Th1 versus Th2 reponses, Treg  cells, cytokine 

production profile).

 

 

Recombinant bacterial based mucosal vaccine against T. gondii

 

Expression of SAG1, a surface antigen of T. gondii, by lactic acid

bacteria (L. plantarum) with Th1 promoting properties

 

Use as an oral vaccine in a model of T.gondii infection – evaluation of  

immunogenicity and protection

 

 

(Studies in cooperation with Institute Pasteur de Lille Grant Amadeus A/F 

and the Dept. of Pediatrics, Vienna)
