immune system
abnormal macrophage physiology ( J:128405 )
• peritoneal macrophages of homozygous mutant mice fail to produce tumor necrosis factor (TNF-) alpha in response to oligodeoxynucleotides containing unmethylated CpG motifs (CpG ODNs)
• TNF-alpha production by homozygous mutant macrophages is normal following stimulation with MALP-2 (macrophage-activating lipopeptide-2, a TLR2/6 ligand), Pam3CSK4 (a triacyl lipopeptide and TLR2/1 ligand), poly I:C (a TLR3 ligand), lipopolysaccharide (LPS, a TLR4 ligand), and R-848 (resiquimod, a single-stranded RNA mimetic and TLR7 ligand)
increased susceptibility to Herpesvirales infection ( J:128405 )
• homozygous mutant mice died within 6 days after infection with a normally sublethal inoculum (1 x 105 CFU) of mouse cytomegalovirus (MCMV), while infected wild-type mice showed no sign of sickness

abnormal macrophage physiology ( J:128405 )
• in response to CpG ODN, macrophages from mice heterozygous for the Cpg2 mutation produce an amount of TNF-alpha intermediate between homozygous mutant and wild-type levels
