Development of anaemia in inflammatory diseases is cytokine-mediated. Specifically, the levels of tumour necrosis factor-alpha (TNF-alpha), produced by activated macrophages, are correlated with severity of disease and anaemia in infections and chronic disease. In African trypanosomiasis, anaemia...

C57BL/6 mice deficient in one or two copies of the gene for tumor necrosis factor alpha (TNF-alpha) were more susceptible to Trypanosoma congolense infection than their resistant, wild-type counterparts. The number of TNF-alpha genes was correlated with the capacity to control parasitaemia and ...

A number of linkage studies in human populations have identified a locus ( pfbi) on Chromosome 5q31-q33 controlling Plasmodiun falciparum blood infection levels. This region contains numerous candidate genes encoding immunological molecules such as cytokines, growth factors and growth-factor rec...

Mapping of a new quantitative trait locus for resistance to malaria in mice by a comparative mapping approach with human chromosome 5q31-q33
The TNF-alfa gene on mouse chromosome MMU17 is among the candidates for the trypanosomosis resistance QTG Tirl. Tit t has the largest effect of those loci so far detected which influence degree of resistance to murine trypanosomosis caused by Trypanosome congolense infection. We therefore studied...
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...

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 alp...

Tumor necrosis factor-[alpha] (TNF-[alpha]) plays a role in the host's defence against infections with African trypanosomes. It helps to control the blood stream form of the parasite and in Trypanosoma congolense infections, it also prolongs survival. The mechanisms by which this cytokine can inf...
