8 mar 2023 ano - Indigenous groups in the Amazon discovered to have evolved resistance to Chagas

Descrição:

Positive selection of the PPP3CA gene variant found in Amazonian tribes is thought to have begun around 7500 years ago, when Chagas likely affected Indigenous groups in the Amazon. This is consistent with archaeological findings in the area. T. cruzi infection was first discovered in 9000-year-old mummies from northern Chile and southern Peru.
