F4/80 Knock-out Mouse Model
Strain: F4/80 knockout, Background: C57BL/6
Macrophages play a crucial role in the defense against pathogens. Distinct macrophage populations can be defined by the expression of restricted cell surface proteins. Resident tissue macrophages, encompassing Kupffer cells of the liver and red pulp macrophages of the spleen, characteristically express the F4/80 molecule, a cell surface glycoprotein related to the seven transmembrane-spanning family of hormone receptors. Gene targeting was used to simultaneously inactivate the F4/80 molecule in the germ line of the mouse and to produce a mouse line that expresses the Cre recombinase under the direct control of the F4/80 promoter (F4/80-Cre knock-in). F4/80-deficient mice are healthy and fertile.
The University’s policy is to minimise the use of animals in research, consistent with the need to make significant advances on important problems of human health. Where animal research is necessary, the University will provide housing and care that exceeds, wherever possible, legal requirements. The University will also continually pursue techniques that reduce the number of animals involved in research. For further information about animal research at Oxford, click here.
