  28. The role of Gq in insulin resistant cardiac hypertrophy
    Patrick Yue; Fiscal Year: 2006
    ..Specific Aim 3: To study the effect of Gq ablation on the MAPK signaling cascade, a major pathway leading to hypertrophy. ..
  29. Matrix metalloproteinase-9 mediated cell death in stroke
    ENG LO; Fiscal Year: 2009
    ..Our lab and others have established MMP-9 as a key extracellular protease that modifies neurovascular homeostasis. These proposed studies should help reveal the mechanisms of MMP-9 mediated cell death in stroke. ..
  30. Role of calcium and reactive oxygen species in toxicant-induced immune failure
    Mohamed Trebak; Fiscal Year: 2007
    ..This effort will contribute to both a better understanding of normal and pathological lymphocyte immunity as well as to the discovery of new therapies for diseases such as immunodeficiency and cancer. ..
  31. MATRIX METALLOPROTEINASE AND APOPTOSIS IN BRAIN TRAUMA
    ENG LO; Fiscal Year: 2004
    ..To date, there are not effective treatments for traumatic brain injury. Results from these proposed experiments will help identify MMP and upstream MAP kinase pathways as viable therapeutic targets for this devastating condition. ..
  32. MECHANISMS OF HEMORRHAGE AND EDEMA IN TPA STROKE THERAPY
    ENG LO; Fiscal Year: 2006
    ..This proposal should fit the goals of the Stroke PRG because it examines novel mechanisms that link tPA, cell signaling, MMPs, and hemorrhagic transformation in the neurovascular unit. ..
  33. HIV Compromises Lung Macrophage TLR Host Defense Function
    SOUVENIR TACHADO; Fiscal Year: 2009
    ..Our goal is to define the molecular mechanisms why these patients are susceptible to opportunistic infections and identify targets that can enhance the immune response of these patients. ..
  34. MECHANISMS OF HEMORRHAGE AND EDEMA IN TPA STROKE THERAPY
    ENG LO; Fiscal Year: 2003
    ..This proposal should fit the goals of the Stroke PRG because it examines novel mechanisms that link tPA, cell signaling, MMPs, and hemorrhagic transformation in the neurovascular unit. ..
  35. tPA plus MMP inhibition for combination stroke therapy
    ENG LO; Fiscal Year: 2007
    ..End of Abstract) ..
  36. MECHANISMS OF HEMORRHAGE AND EDEMA IN TPA STROKE THERAPY
    ENG LO; Fiscal Year: 2001
    ..Since the likelihood of reperfusion injury is related to the degree of vascular damage, this method should have predictive value by assessing cerebrovascular integrity prior to thrombolytic therapy. ..
  37. Regulation of epithelial contact inhibition by Rac effector proteins
    Mirjam Zegers; Fiscal Year: 2007
    ..We anticipate that the results of our studies will yield novel and fundamental insights into the biology of epithelial morphogenesis. ..
