This research explores T-cell activation, glomerular disease pathogenesis, and protein kinase regulation. Key findings involve the immunologic synapse, podocyte function in kidney failure, and scaffold protein KSR's role in MAPK activation.

Area of Science:

  • Immunology
  • Nephrology
  • Molecular Biology

Background:

  • Investigating the mechanics of T-cell activation, including protein phosphorylation and immunologic synapse function.
  • Examining the pathogenesis of glomerular disease, focusing on podocyte function and genetic deficiencies.
  • Studying modifiers of protein kinase cascades, specifically scaffold proteins like KSR.

Purpose of the Study:

  • To define the function of the immunologic synapse in T-cell activation.
  • To understand how CD2AP deficiency in podocytes contributes to kidney failure.
  • To elucidate the role of KSR in regulating mitogen-activated protein kinase (MAPK) activation.

Main Methods:

  • Utilizing techniques to study T-cell receptor engagement and protein phosphorylation.
