Th2 cells are able to make unpleasant the life of parasites in the host and tend to limit potentially harmful Th1-mediated responses. Thus, Th2 cells may be regarded as a part of down-regulatory (or suppressor) mechanism for exaggerated and/or inappropriate Th1 responses. The Th1/Th2 ...
Nude rats have been used in studies related to a variety of parasites. Infection of nude rats with, for example, Entamoeba histolytica resulted in shedding of organisms for more than 1 year (Owen 1987); cryptosporidial infection was established in nude rats, with prolonged shedding and defectiv...

Recent research in neuroimmunology has revolutionized our understanding of the intricate interactions between the immune system and the central nervous system (CNS). The CNS, an “immune-privileged organ”, is now known to be intimately connected to the
Most, if not all, cells in humans and mice express the receptor for type I interferons (IFNs). Therefore, these cytokines have a range of direct and indirect effects on various cell types during infection with viruses, bacteria, parasites and fungi. Type I IFNs are important for host defen...

Our objective was to test the association between human co-infection with intestinal parasites and host parasitaemia, infectiousness to the vector and immunological profiles inTrypanosoma cruzi-seropositive individuals residing in an endemic region of the Argentine ...
