Structural Analyses of a Dominant Cryptosporidium parvum Epitope Presented by H-2K Offer New Options To Combat Cryptosporidiosis.

Cryptosporidium parvum has gained much attention as a major cause of diarrhea in the world, particularly in those with compromised immune systems. The data currently available on how the immune system recognizes C. parvum are growing rapidly, but we lack data on the interactions among host major histocompatibility complex (MHC) diversity and parasitic T-cell epitopes.
