Understanding the genetic control of immune-cell development is enhanced by human and mouse genome sequences. Researchers can identify gene functions using expression profiling or gene knockouts in embryonic stem cells.

Area of Science:

  • Genomics
  • Immunology
  • Developmental Biology

Background:

  • The draft sequences of the human and mouse genomes offer significant potential for advancing our understanding of immune system development.
  • Identifying the genetic underpinnings of immune cell differentiation and function is crucial for both basic research and clinical applications.

Purpose of the Study:

  • To outline strategies for leveraging genomic information to elucidate the genetic control of immune-cell development.
  • To explore methods for linking specific gene sequences to immune system functions.

Main Methods:

  • Utilizing mRNA-expression profiling to analyze gene activity related to immune cell development.
  • Generating gene knockouts in embryonic stem cells using techniques such as the Cre/Lox system, tetracycline operon, gene-trap methods, or chemical mutagenesis.
