Molecular Immunology

Cytokines are critical secreted molecules that control the development, growth, differentiation, and function of cells that comprise the immune system. The Laboratory of Molecular Immunology, led by Dr. Warren J. Leonard, focuses on the biology, signaling, and molecular regulation of a key family of these cytokines, the common gamma chain family of cytokines, with studies ranging from basic molecular mechanisms to human disease.
