  1. LPA and Edg Receptors in the Pulmonary Immune Respose
    STEVE NICHOLAS GEORAS; Fiscal Year: 2010
    ..The goal of our research program is to define the role of new molecules that cause lung inflammation in asthma with the hope that this will lead to the use of new therapeutic agents in this disease. ..
  2. LPA and Edg Receptors in the Pulmonary Immune Respose
    Steve Georas; Fiscal Year: 2007
    ..Taken together, these studies will provide the first comprehensive analysis of a novel lysophospholipid and signal transduction pathway in allergic inflammatory diseases. ..
  3. Yin-Yang-1:a novel transcription factor in Th responses
    Steve Georas; Fiscal Year: 2006
    ..Taken together, our studies will define novel factors and pathways involved in the molecular regulation of Th2 gene expression and in the pulmonary response to allergen. ..
