N normal phenotype
immune system
• exhibited no type I interferon production in response to smooth LPS
• exhibited no TNF production in response to smooth lipopolysaccharide (LPS), however response to lipid A from Salmonella Minnesota was normal
• macrophages exposed to vesicular stomatitis virus (VSV) could not contain the infection and were more susceptible to lysis than controls

Background
involves: 129S4/SvJae * C57BL/6J

Mouse lines carrying:
Cd14tm1Frm mutation (2 available); any Cd14 mutation (22 available)
phenotype observed in females
phenotype observed in males
N normal phenotype
immune system
• macrophages exhibited loss of cytokine production in response to LPS and low levels of heat-killed E.coli (less than 1 E.coli per cell), however macrophages stimulated with high levels (10 E.coli per cell) of heat-killed E.coli, produced cytokine levels similar to wild-type while macrophages stimulated with lower levels (less than 10 E.coli per cell) produced reduced cytokine levels
• no IL-6 production by macrophages in response to LPS from E.coli K235
• no TNF-alpha production by macrophages in response to LPS from E.coli K235 or to low levels of heat-killed E.coli (less than 1 E.coli per cell)
