Research Focus

Immunotherapy denotes an important strategy for manipulating a patient's immune response. In cancer or infectious diseases the approach is designed to boost the patient's immune response toward tumor antigens or pathogens. Conversely, immunotherapeutic strategies in autoimmunity or allergy are designed to silence the patient's response against autoantigens or allergens.

Currently my research focus is on characterization of porin proteins of Gram-negative pathogenic bacteria for host immunomodulatory roles and detailed immune cell signalling mechanisms.

We already know dendritic cells (DCs) are a class of professional antigen-presenting cells with a unique ability to induce primary immune responses as well as immunological tolerance depending on the activation and maturation states of these cells. In future my research focus will be toward understanding the immunobiological processes to generate immunotherapeutic strategies employing DCs as tool for presenting antigens to T cells in such a manner to generate either immune responses or tolerance depending on the disease model.
