Malaria in pregnancy remains a substantial public health concern in malaria-endemic areas. Accumulation of maternal immune cells in the placenta and increased levels of inflammatory cytokines caused by sequestration of Plasmodium falciparum-infected erythrocytes (IE) in the placental intervillous blood spaces have been associated to poor neonatal outcomes, including low birth weight due to fetal growth restriction. However, little is known about the molecular changes occurring in the placenta in past-stages of P. falciparum infection when the hemozoin pigment is present in the absence of parasites. We conducted an integrated proteome, phosphoproteome and glycoproteome analysis in P. falciparum infected and non-infected placentas aiming to find molecular changes occurring in past-stage infection. A total of 2946 proteins, 1733 glycosites and 4100 phosphosites were identified and quantified in this study, disclosing overrepresented processes related to oxidative stress, protein folding and regulation of apoptosis, as well as AKT and ERK signaling pathways activation, which together with clinical data and literature-based information were further correlated to an increased apoptosis in infected placentas. This study showed apoptosis-related mechanisms associated with past-stage of malaria infection that can be further explored as therapeutic target against adverse pregnancy outcomes in placental malaria.
