Functional overlap in the src gene family: inactivation of hck and fgr impairs natural immunity.

Abstract excerpt

We have generated mice with targeted disruptions of the src-like genes hck and fgr to assess the role of these kinases in myeloid cell development and function. Hematopoiesis appears to proceed normally in both hck-l- and fgr-l- animals, and in hck-l(-)-fgr-l- double homozygotes, but phagocytosis is impaired in hck-l- macrophages. Macrophages cultured from doubly homozygous, hck-l(-)-fgr-l- animals retain many...
