Incomplete recruitment of protective T cells is associated with trypanosoma cruzi persistence in the mouse colon

AI Ward, MD Lewis, MC Taylor, JM Kelly - Infection and Immunity, 2022 - Am Soc Microbiol
Trypanosoma cruzi is the etiological agent of Chagas disease. Following T cell-mediated
suppression of acute-phase infection, this intracellular eukaryotic pathogen persists long …

In Vivo Analysis of Trypanosoma cruzi Persistence Foci at Single-Cell Resolution

AI Ward, MD Lewis, AA Khan, CJ McCann… - Mbio, 2020 - Am Soc Microbiol
Infections with Trypanosoma cruzi are usually lifelong despite generating a strong adaptive
immune response. Identifying the sites of parasite persistence is therefore crucial to …

A modified drug regimen clears active and dormant trypanosomes in mouse models of Chagas disease

JM Bustamante, F Sanchez-Valdez… - Science translational …, 2020 - science.org
A major contributor to treatment failure in Chagas disease, caused by infection with the
protozoan parasite Trypanosoma cruzi, is that current treatment regimens do not address the …

[HTML][HTML] Trypanosoma cruzi amastigote transcriptome analysis reveals heterogenous populations with replicating and dormant parasites

H Desale, C Herrera, E Dumonteil - Microbes and Infection, 2024 - Elsevier
Trypanosoma cruzi is a protozoan parasite causing Chagas disease, with a complex life

Transcriptome profile of Trypanosoma cruzi-infected cells: simultaneous up- and down-regulation of proliferation inhibitors and promoters

T Shigihara, M Hashimoto, N Shindo, T Aoki - Parasitology research, 2008 - Springer
As Trypanosoma cruzi, the etiological agent of Chagas disease, multiplies in the cytoplasm
of nucleated host cells, infection with this parasite is highly likely to affect host cells. We …

Putting infection dynamics at the heart of Chagas disease

MD Lewis, JM Kelly - Trends in parasitology, 2016 - cell.com
In chronic Trypanosoma cruzi infections, parasite burden is controlled by effective, but
nonsterilising immune responses. Infected cells are difficult to detect because they are …
