Gestational age-related changes in the peripheral blood cell composition of sub-Saharan African women Ibitokou, S. /Brutus, Laurent Vianou, B. Oesterholt, M. Massougbodji, A. /Deloron, Philippe Troye-Blomberg, M. /Fievet, Nadine /Luty, Adrian Pregnancy Peripheral blood mononuclear cells African women Longitudinal cohort study Lymphocytes Antigen-presenting cells Gestational age-related changes in the cellular composition of peripheral blood have not been described in sub-Saharan African settings. We conducted longitudinal cohort studies in Beninese and Tanzanian mothers with quantification of peripheral blood mononuclear cell-types ex vivo using flow cytometry. Between the second trimester and delivery the frequency of CD4(+) T cells declined significantly, contrasting with a non-significant increase in CD8(+) T cells, but no changes in T-regulatory, NK or NKT cell frequencies. Antigen-presenting cell profiles were also unaltered, although non-significant trends were evident. These changes resemble in some respects those reported during pregnancies in developed countries, but differ in others. 2013 text https://www.documentation.ird.fr/hor/fdi:010060425 fdi:010060425 Ibitokou S., Brutus Laurent, Vianou B., Oesterholt M., Massougbodji A., Deloron Philippe, Troye-Blomberg M., Fievet Nadine, Luty Adrian.
