Human telomeres are several kilobases of repeated (TTAGGG)(n) sequences at the ends of chromosomes, a short fragment of which is lost with each cell division. This shortening serves as a "mitotic clock" which limits the number of divisions that a nor

We studied the suppressive effects induced in phytohemagglutinin (PHA)-stimulated human peripheral blood mononuclear cells (PBMC) by purified blood forms of Trypanosoma brucei rhodesiense. The parasite was found to markedly impair lymphocyte prolifer

Nitrate from drinking water is converted in the body to nitrite by bacteria in the gut. This project examined effects of nitrate/nitrite on immune functions, i.e., human lymphocyte proliferation and cytokine production. Nitrate had no effect on lymph

Coculture of blood forms of Trypanosoma cruzi with human peripheral blood mononuclear cells stimulated with anti-CD2(2) and anti-CD2(3) monoclonal antibodies, i.e., via an antigen-independent pathway of T-lymphocyte activation, resulted in marked imm

Coculture of blood forms of Trypanosoma cruzi with human PMBC suppresses the expression of several molecules involved in lymphocyte activation, including receptors for IL-2. Our work was initially undertaken to establish whether this effect required

Co-culture of blood forms of Trypanosoma cruzi, the causative agent of Chagas' disease, with human PBMC impaired the capacity of T lymphocytes to express surface receptors for IL-2. This effect was evidenced by marked reductions in both the proportio

We previously established that Trypanosoma cruzi, the causative agent of Chagas' disease, has the ability to suppress expression of the p55 component of the IL-2R by activated human PBMC. We explored in this work whether the parasite alters the expre

Among the known life cycle stages of Trypanosoma cruzi only the amastigote form bound lactoferrin (LF), a glycoprotein produced by neutrophils. This capacity was readily demonstrable by indirect immunofluorescence in amastigotes derived from mice, a
