74. What specific challenge does Trypanosoma brucei present to the immune system?

 

 

1. It frequently changes its antigens, staying one step ahead of the host’s antibody response.

 

1. It specifically attacks B-lymphocytes preventing activation and antibody production.

 

1. It specifically attacks T-lymphocytes preventing their activation and crippling the cell-mediated immune response.

 

1. Its antigens are not recognized by B and T-lymphocytes so these host defense cells don’t respond to the infection.
