Volunteers were assessed at study entry, the day of the third vaccination and 24, 72 hours, two weeks after vaccination, and 5 days after challenge. 13/39 vaccinees were protected and 26/39 were not protected. Eleven vaccinees exhibited delayed onset of parasitemia. All infectivity controls developed parasitemia. Prediction Analysis of Microarrays (PAM-R) identified genes corresponding with protection. Gene Set Enrichment Analysis (GSEA) identified sets of genes associated with protection after the third immunization, before challenge.
Expression of genes associated with immunoproteasome processing of major histocompatibility complex peptides is indicative of protection with adjuvanted RTS,S malaria vaccine.

View SamplesWe applied a systems biology approach to study immune responses in subjects receiving 3 consecutive immunizations with RTS,S/AS01 (RRR), or in those receiving 2 immunizations of RTS,S/AS01, following a primary immunization with adenoviral Ad35 (ARR) vector expressing circumsporozoite protein.

View SamplesExpression analysis revealed that UBD is a down-stream element of Foxp3 in human activated regulatory CD4+ T cells (Treg).
UBD, a downstream element of FOXP3, allows the identification of LGALS3, a new marker of human regulatory T cells.

View SamplesGoals and objectives of this study: to identify genes preferentially induced in human CD4+CD25hi Treg cells following T-cell activation with potential role for stabililization & maintenance of the regulatory program.
GARP: a key receptor controlling FOXP3 in human regulatory T cells.
