Abstract

Complement factor 5a (C5a) promotes local inflammation and is a potent chemoattractant for neutrophils and macrophages. We had an interest in C5a and its receptor, C5r1, because we previously identified C5a as a positional candidate gene for the quantitative trait locus Abhr2, which determines allergen-induced bronchial hyperresponsiveness in our murine model of asthma. To study the significance of C5r1 in our asthma model we first had to determine its genomic map location in mice. Genomic sequence surrounding murine C5r1 was analyzed for polymorphisms and two variable microsatellites were identified. These microsatellites were genotyped in A/J x (C3H/HeJ x A/J)F1 backcross mice (n = 355) and mapped in a panel of 164 markers spaced at approximately 10 cM intervals throughout the genome. Multipoint linkage analysis placed C5r1 on murine chromosome 7, 3.9 cM from the top of the linkage group. This map location has been previously identified as containing an additional quantitative trait locus for allergen-induced airway hyperresponsiveness, Abhr3, in this population of mice.
