Two bovine bacterial artificial chromosome clones were screened by PCR to amplify the tumour necrosis factor alpha (TNFA) gene. DNA extraction and Southern blotting and probing with a (GT)10 oligonucleotide were performed, followed by cloning into the pUC19 vector. A 0.9 kb fragment containing se...

The C57BL/6 BALB/c and A/J inbred laboratory mouse strains often express different response phenotypes when challenged with a variety of infectious agents (Morrison et al. 1978; Bradley 1977; Hormmaeche et al. 1985). In view of the pivotal role of tumor necrosis factor Tnfa in innate immunity, we...

The tumor necrosis factor (TNF) locus comprises the tandemly arranged genes coding for Tnfa (cachectin) and Tnfb (lymphotoxin-alpha) (Semon et al 1987). In mice, the TNF locus is located on chromosome 17 (MMU17) in the major histocompatibility complex (MHC) region. Tnfa and soluble lymphotoxin al...

In view of the Tnfa gene location within the major histocompatibility (MHC) region and reports of its importance in disease protection activity, this paper examines the TNF a genes of a number of different mouse strains which were known to be of different disease response phenotypes. Twelve inbre...

A marker-assisted introgression (MAI) experiment was conducted to transfer trypanotolerance quantitative trait loci (QTL) from a donor mouse strain, C57BL/6, into a recipient mouse strain, A/J. The objective was to assess the effect of three previously identified chromosomal regions on mouse chro...

The host-protective immune response to infection with gastrointestinal (GI) nematodes involves a range of interacting processes that begin with recognition of the parasite's antigens and culminate in an inflammatory reaction in the intestinal mucosa. Precisely which immune effectors are responsib...

Since the publication of the mouse genome, attention has focused on the strains that were selected for sequencing. In this paper we report the results of experiments that characterized the response to infection with the murine gastrointestinal nematode Heligmosomoides polygyrus of eight new strai...

Tsetse fly-transmitted trypanosomes (Trypanosoma spp.) cause 'sleeping sickness' in man and have a serious impact on livestock-based agriculture in large areas of Africa. Multigene control of variation in susceptibility to trypanosomiasis is known to occur in mice, where the C57BI/6 (B6) strain i...

In the present study, we used newly developed F11 generation mouse advanced intercross lines (AIL) to fine map Pas1–3 quantitative trait loci (QTL). The (A/J x C57BL/6) F11 AIL mouse population was created by crossing lung tumor-resistant C57BL/6 mice with lung tumor-susceptible A/J mice. By se...

We have previously obtained strong evidence for linkage of mild malaria attack to the MHC region, with a peak close to the tumor necrosis factor (TNF) gene. We screened, for polymorphisms, the entire TNF gene in the same sample of 34 families comprising 197 individuals living in a Plasmodium falc...
