Area of Science:

  • Immunology
  • Molecular Biology
  • Cell Signaling

Background:

  • B cells are critical components of the adaptive immune system, playing vital roles in both health and disease.
  • The nuclear factor-kappaB (NF-kappaB) signaling pathway is a key regulator of immune cell development and function.
  • Previous studies using knockout (KO) mice have demonstrated the importance of NF-kappaB transcription factors in B cell biology.

Purpose of the Study:

  • To investigate the role of NF-kappaB signaling in B cell development and function.
  • To explore the involvement of newly generated KO mouse models for NF-kappaB pathway components in understanding B cell signaling.
  • To identify critical signaling pathways regulating B cell function via NF-kappaB.

Main Methods:

  • Utilized knockout (KO) mouse models targeting various members of the NF-kappaB family.
