Neutralization of the activity of a Fasciola hepatica cathepsin L proteinase by anti-cathepsin L antibodies.

abstract：:The opportunistic protozoan parasite Toxoplasma gondii is well known as a strong inducer of cell-mediated immunity, largely as a result of proinflammatory cytokine induction during in vivo infection. Yet, during intracellular infection the parasite suppresses signal transduction pathways leading to these proinflammato...
