Genome-wide scans were conducted for tuberculosis and leprosy per se in Brazil. At stage 1, 405 markers (10 cM map) were typed in 16 (178 individuals) tuberculosis and 21 (173 individuals) leprosy families. Nonparametric multipoint analysis detected 8 and 9 chromosomal regions respectively with provisional evidence (P<0.05) for linkage. At stage 2, 58(More)
Nramp1 regulates macrophage activation in infectious and autoimmune diseases. Nramp2 controls anaemia. Both are divalent cation (Fe(2+), Zn(2+), and Mn(2+)) transporters; Nramp2 a symporter of H(+) and metal ions, Nramp1 a H(+)/divalent cation antiporter. This provides a model for metal ion homeostasis in macrophages. Nramp2, localised to early endosomes,(More)
A genome-wide scan was conducted for visceral leishmaniasis (VL) in Brazil. Initially, 405 markers were typed in 22 multicase pedigrees (28 nuclear families; 174 individuals; 66 affected). Non-parametric multipoint analysis detected nine chromosomal regions with provisional evidence (logarithm of the odds (LOD) scores 0.95–1.66; 0.003<P<0.018) for linkage.(More)
To identify susceptibility loci for visceral leishmaniasis, we undertook genome-wide association studies in two populations: 989 cases and 1,089 controls from India and 357 cases in 308 Brazilian families (1,970 individuals). The HLA-DRB1–HLA-DQA1 locus was the only region to show strong evidence of association in both populations. Replication at this(More)
Toxoplasma gondii infection is an important mediator of ocular disease in Brazil more frequently than reported from elsewhere. Infection and pathology are characterized by a strong proinflammatory response which in mice is triggered by interaction of the parasite with the toll-like receptor (TLR)/MyD88 pathway. A powerful way to identify the role of TLRs in(More)
L. braziliensis causes cutaneous (CL) and mucosal (ML) leishmaniasis. Wound healing neutrophil (PMN) and macrophage responses made following the bite of the vector sand fly contribute to disease progression in mice. To look at the interplay between PMN and macrophages in disease progression in humans we asked whether polymorphisms at genes that regulate(More)
Approaches based on linear mixed models (LMMs) have recently gained popularity for modelling population substructure and relatedness in genome-wide association studies. In the last few years, a bewildering variety of different LMM methods/software packages have been developed, but it is not always clear how (or indeed whether) any newly-proposed method(More)
The region of conserved synteny on mouse chromosome 11/human 17q11–q21 is known to carry a susceptibility gene(s) for intramacrophage pathogens. The region is rich in candidates including NOS2A, CCL2/MCP-1, CCL3/MIP-1α, CCL4/MIP-1β, CCL5/RANTES, CCR7, STAT3 and STAT5A/5B. To examine the region in man, we studied 92 multicase tuberculosis (627 individuals)(More)
To determine whether variation in two interleukin 1 family genes (IL1B and interleukin 1 receptor antagonist, IL1RN) is associated with pulmonary tuberculosis (TB), two published polymorphisms at nucleotide positions -511 and +3953 in IL1B and one in the IL1RN 86 bp VNTR were genotyped in 335 smear positive Gambian TB patients, and 298 ethnically matched(More)
In the 1970s and 1980s, analysis of recombinant inbred, congenic and recombinant haplotype mouse strains permitted us to effectively 'scan' the murine genome for genes controlling resistance and susceptibility to leishmanial infections. Five major regions of the genome were implicated in the control of infections caused by different Leishmania species(More)
