Researchers have uncovered a sophisticated mechanism employed by the parasite responsible for the fatal sleeping sickness, enabling it to remain undetected within the human bloodstream. This cunning strategy involves a newly identified protein, designated ESB2, which functions as a “molecular shredder.”
ESB2 meticulously degrades specific genetic instructions during their production, essentially silencing signals that would otherwise reveal the parasite’s presence. By doing so, the parasite can liberally coat its surface with defensive proteins while simultaneously preventing the expression of markers that could trigger an immune response.
