Mouse infection studies had been carried out as previously described9 in sex-matched and closely age-matched groups of adult Crp knockout and wild-type control C57BL/6 mice, and have been humanely killed at 72 hr.Non-infectious challengesC-reactive protein might have a part in preventing ANA formation12?4 and spontaneous ANA production became considerably greater among female but not male Crp knockouts at 9 months of age ( mice with ANA good at 1 : 80 serum dilution, n = 22 per group, P = 0.03 by Fisher's exact test) and 12 months of age (P = 0.002, n = 21) (Fig. two). A Crp transgenic study is expected to identify regardless of whether this modest effect is certainly due to CRP deficiency since the sle1 locus, which controls ANA production, is adjacent to the Crp gene on distal mouse chromosome 1. Even so, the response to immunization with apoptotic thymocytes did not differ in between wild-type and Crp knockout mice (not shown).Study approvalAll mouse experiments have been completely compliant with UK Property Office regulations, approved by the UCL Institutional Review Board.?2014 The Authors.
