Scand J Immunol
. 2010 Apr;
71(3):220-5.
PMID: 20415787
Neurotrophic receptors TrkA and TrkC double up as receptors that Trypanosoma cruzi uses to invade cells and as autoantigen in T. cruzi-infected individuals (with Chagas' disease). Consequently, autoantibodies against TrkA...

. 2008 Jul;
135(11):1337-42.
PMID: 18664306
Chagas' disease is one of the few functional gastrointestinal disorders for which a causative agent has been identified. However, some pathological aspects of the chagasic megasyndromes are still incompletely understood....

Scand J Immunol
. 2008 Apr;
67(6):603-9.
PMID: 18410251
The Chagas' disease parasite Trypanosoma cruzi promotes survival and differentiation of neurones by binding and activating nerve growth factor (NGF) receptor TrkA. The functional mimic of NGF in T. cruzi...

Dig Dis Sci
. 2007 Mar;
52(10):2877-83.
PMID: 17385032
Neuronal destruction has been considered the hallmark of pathogenic mechanisms in chagasic megacolon. Characterization of neuropeptides in the enteric nervous system from chagasic patients with megacolon could elucidate some aspects...

Parasitol Res
. 2002 Sep;
88(10):894-900.
PMID: 12209329
In the present study, we evaluated for the first time the profile of blood parasitism in untreated, chronic Chagas' disease. The study was conducted on 60 patients and a control...

Trends Parasitol
. 2001 May;
17(6):286-91.
PMID: 11378036
Diagnosis of individuals infected by Trypanosoma cruzi is performed mainly by serological tests using crude antigens, which might crossreact with other infections. In the past ten years, many recombinant T....

Carcinogenesis
. 2001 Apr;
22(5):737-40.
PMID: 11323392
Experimental data have demonstrated that chronic infection with intracellular parasites may enhance resistance against some types of tumour. This phenomenon has not yet been demonstrated for experimental Trypanosoma cruzi chronic...

Serodiagnosis of Trypanosoma cruzi infection using the new particle gel immunoassay--ID-PaGIA Chagas
Rabello A, Luquetti A, Moreira E, Gadelha M, Dos Santos J, de Melo L, et al.
Mem Inst Oswaldo Cruz
. 1999 Feb;
94(1):77-82.
PMID: 10029915
The ID-Chagas test is a particle gel immunoassay (PaGIA). Red coloured particles are sensitised with three different synthetic peptides representing antigen sequences of Trypanosoma cruzi: Ag2, TcD and TcE. When...

J Clin Microbiol
. 1997 Jul;
35(7):1829-34.
PMID: 9196203
The diagnosis of Chagas' disease relies mostly on data provided by immunologic tests, but inconclusive results often require elucidation, especially in blood banks. When six different types of Trypanosoma cruzi...
