Does cyclophosphamide play a protective role against neuronal loss in chronic T. cruzi infection?

In this study, we verified the possible role of cyclophosphamide (CY) in protecting or not against neuronal losses in young and aged male Calomys callosus chronically infected with the MORC-1 strain of Trypanosoma cruzi through numerical quantification of neurons from the myenteric plexus of the colon and quantification of nitric-oxide concentration (NO) during the acute and chronic phase of infection. For this purpose, groups of young C. callosus were infected with the MORC-1 strain of T.

Could cyclophosphamide exert a protective role avoiding esophagic neuron loss in Calomys callosus infected with Trypanosoma cruzi?

The protective role of cyclophosphamide was studied in this work. Young male Calomys callosus were infected with Trypanosoma cruzi and allowed to age. Cyclophosphamide therapy was administered to animals during acute and late chronic phases of infection.

Dehydroepiandrosterone affects Trypanosoma cruzi tissue parasite burdens in rats.

Dehydroepiandrosterone (DHEA), the predominant steroid hormone produced by adrenal glands has significant effects on the immune system. DHEA enhances immune responses against a wide range of viral, bacterial, and parasitic pathogens. In the present study, we investigated the effects of DHEA treatment during the acute phase of experimental Trypanosoma cruzi infection.

Melatonin treatment reduces the severity of experimental Trypanosoma cruzi infection.

Prior studies show that melatonin enhances the immune response. This study investigated the possible therapeutic effects of melatonin during the course of Trypanosoma cruzi infection. T.

Influence of Trypanosoma cruzi chronic infection in the depletion of esophageal neurons in Calomys callosus.

The extent of neuronal loss was studied in this work, in aged female Calomys callosus infected with the MORC-1 strain of Trypanosoma cruzi. Fifteen months after infection, one group of animals was immunosuppressed with cyclophosphamide (CY). Sections of the distal esophagus were collected and stained with cresyl violet.
