Qualitatively distinct patterns of cytokines are released by human dendritic cells in response to different pathogens

Enterovirus-Infected β-Cells Induce Distinct Response Patterns in BDCA1+ and BDCA3+ Human Dendritic Cells

Enteroviruses often cause mild disease, yet are also linked to development of autoimmune diabetes. Dendritic cells (DCs) shape both innate and adaptive immune responses, including anti-viral responses. How different human DC subsets shape anti-viral responses, whether they have complementary or overlapping functions and how this relates to autoimmune responses is largely unknown. We used entero...

Distinct modulation of chemokine expression patterns in human monocyte-derived dendritic cells by prostaglandin E(2).

Dendritic cells (DCs) are key in regulating immune responses. DCs reside in tissues facing the environment and sample their surrounding for pathogens. Upon pathogen encounter, DCs mature and migrate into secondary lymphoid organs. Distinct maturation signals dictate the ability of DCs to produce distinct patterns of chemokines that orchestrate immunity. Prostaglandin E(2) (PGE(2)) is produced d...

Dendritic Cells Induced by Tlr4 or Tlr3 in Human of Th1 Cytokines That Are Specifically Stimulation Blocks the Induction of a Subset Il-10 Released by Concomitant Tlr2

IL-10 released by concomitant TLR2 stimulation blocks the induction of a subset of Th1 cytokines that are specifically induced by TLR4 or TLR3 in human dendritic cells.

Recognition of microbial products through TLRs triggers the expression of several cytokines that regulate innate and adaptive immunity. Signaling by various TLRs is not equivalent and leads to differential gene induction. This study analyzed the responses of human dendritic cells (DCs) and PBMCs stimulated with agonists of TLR2, TLR3, TLR4, TLR5, and TLR7, first individually and then in combina...
