Men suffer amoebic liver abscesses four times more frequently than women. This is also the case for the mice we use as models for human disease.
Radical removing the gonads of male mice makes them partially resistant to amoebas, and injections of testosterone make female mice more susceptible. Interferon (IFNγ) strengthens resistance to amoebas, and immune cells producing IFNγ – the naturally-occurring killer cells – of female mice produced more IFNγ than those of their male counterparts.
