Background: Preeclampsia is a common pregnancy-specific disorder associated with significant maternal and fetal morbidity and mortality worldwide. It has been proposed that the imbalance between two CD4+ T cell subtypes, regulatory T cells (Treg) and T-helper 17 cells (Th17), is involved in the pathophysiology of preeclampsia. Objectives: To determine the serum levels of IL-17, IL-21, IL-23 and...

Interleukin-21 (IL-21) has been described as a potent stimulator of antitumor T-cell immunity, but also of autoimmune reactions and oncogenesis. Antigen presenting cells genetically modified to release IL-21 allow for the expansion of tumor-specific T cells exhibiting favorable effector and growth characteristics and a minimal risk of detrimental side effects.

Abstract Clearance of infection with Plasmodium spp. requires both antibody and Th1-type responses. While Th1-like cells control the peak in P. chabaudi infection, however specific IgG is delayed. Both Tfh GC-Tfh can promote antibodies long-lived plasma to fully clear infection. numbers remain stable throughout while Th1/Tfh hybrid (IFN-g +/IL-21 +CXCR5 int) expand. Testing if triple cytokine r...
