ITGB2 and infection: In the same study, we detected a differential expression pattern between IPN-susceptible and IPN-resistant families in the expression of ccl19 and itβ2 (cd18), noting in the susceptible families an abrupt high expression at 1 day post-infection (dpi) to then drop drastically at 5 dpi, meanwhile the expression in the IPN-resistant families remained constant (Reyes-López et al., 2015).
