Editorial: Masters of fate: the APC cytokine milieu as a key regulator of distinct Tfh cell subsets
Discussion on how DC-derived IL-6 inhibits the differentiation of Tfh cells with a Th2 phenotype.
Spotlight on Leading Edge Research
Antigen-presenting cell-derived IL-6 restricts the expression of GATA3 and IL-4 by follicular helper T cells
IL-6/STAT3 signaling modulates the cytokine and transcription factor pattern of Tfh cells and controls IgE secretion in vivo.
Analysis of the HLA-DR peptidome from human dendritic cells reveals high affinity repertoires and nonconventional pathways of peptide generation
Human DCs present standard HLA-DR peptides repertoires, but also C-terminal peptides from cytosolic proteins and Asp as a major cleavage residue, suggesting non-conventional processing pathways.
