Notch signaling is crucial for cell development, particularly in T cell lineage commitment. Research explores Notch receptors and ligands in various blood cell development stages.

Area of Science:

  • Cellular and Molecular Biology
  • Developmental Biology
  • Immunology

Background:

  • Notch proteins are key regulators of cell fate and differentiation in development.
  • Mammals possess four Notch receptors interacting with five distinct ligands.
  • Notch signaling plays a vital role in various biological processes.

Purpose of the Study:

  • To elucidate the role of Notch signaling in T cell lineage commitment using Notch1 receptor.
  • To investigate the involvement of other Notch receptors and ligands in hematopoiesis and immune cell development.
  • To understand the broader functions of Notch signaling in embryonic and postnatal development.

Main Methods:

  • Utilizing gain-of-function and conditional loss-of-function approaches for the Notch1 receptor.
