Autoimmune diseases, asthma, and chronic allergies result from dysfunctions in the regulation of the immune system. The work in this laboratory is directed towards understanding how allergenic agents and immune complexes activate one particular family of receptors (Fc receptors) and, through them, ultimately control the genes that produce the signals (cytokines) that in turn recruit other cells in the inflammatory response. Understanding this system is essential for developing targeted therapeutic agents that can ameliorate immune system disorders with minimal side effects.
Our laboratory currently concentrate on the following projects:
- Fc epsilon receptor signaling.
- Role of mast cells and basophils in immunity and autoimmunity.
- Molecular regulation of inflammation.
- Sphingolipids role in allergy.
