Story summary

Researchers at Brazil's University of São Paulo have made a groundbreaking discovery: a biomarker linked to COVID-19 resistance in serodiscordant couples. Women who stayed asymptomatic showed elevated levels of the IFIT3 gene, which fights viral replication. In a parallel study, UC Riverside revealed that a variant in the PTPN2 gene heightens vulnerability to SARS-CoV-2 by boosting the ACE2 receptor.
