Differential responses in placenta and fetal thymus at 12 days post infection elucidate mechanisms of viral level and fetal compromise following PRRSV2 infection

Van Goor, Angelica, Pasternak, Alex, Walker, Kristen, Hong, Linjun, Malgarin, Carolina, MacPhee, Daniel J., Harding, John C. S., Lunney, Joan K.
Background:A pregnant gilt infected with porcine reproductive and respiratory syndrome virus (PRRSV) can transmit the virus to her fetuses across the maternal-fetal-interface resulting in varying disease outcomes. However,the mechanisms leading to variation in fetal outcome in response to PRRSV...

Relationships of CD163 and CD169 positive cell numbers in the endometrium and fetal placenta with type 2 PRRSV RNA concentration in fetal thymus

Novakovic, Predrag, Harding, John C. S., Ladning, Andrea, Al-Dissi, Ahmad N., MacPhee, Daniel J., Detmer, Susan E.
Several routes of porcine reproductive and respiratory virus PRRSV transmission across the porcine diffuse epitheliochorial placentation have been proposed, but none have been proven. The objectives of this study were to investigate associations between numbers of CD163 and CD169 positive...

Fetal Metabolomic Alterations Following Porcine Reproductive and Respiratory Syndrome Virus Infection

Malgarin, Carolina M., MacPhee, Daniel J., Harding, John C. S.
PRRSV infection in third-trimester pregnant sows can lead to fetal death and abortions, although the mechanisms triggering these effects are not well understood. Since resistant and susceptible fetuses can coexist in the same litter, we propose that there may be differential mechanisms used by...

Ladinig, Andrea, Stothard, Paul, Bao, Hua, Hong, Linjun, Lunney, Joan K., Harding, John C. S., Wilkinson, Jamie M., Plastow, Graham S.
Background Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) infection of pregnant pigs can result in congenital infection and ultimately fetal death. Little is known about immune responses to infection at the maternal-fetal interface and in the fetus itself, or the molecular events...

Maternal and fetal thyroid dysfunction following porcine reproductive and respiratory syndrome virus2 infection

Pasternak, J. Alex, MacPhee, Daniel J., Harding, John C. S.
To better understand the host response to porcine reproductive and respiratory virus-2 (PRRSV2) we evaluated circulating thyroid hormone and associated gene expression in a late gestation challenge model. Pregnant gilts were inoculated at gestation day 85 and fetal samples collected at either 12...
