Mouse Th1 cells/Direct stimulation ↗IFN-γ, cellular survival and proliferation in the absence of TCR stimulation; not observed for ligands of other TLRs
Human Mo-LC/MALP-2 and PGN ↗IL-6, IL-1β, and IL-23 by Mo-LC; ↗IL-17 by allogeneic CD4+ T cells cocultured with CD1+ Mo-LC stimulated with PGN or Pam3CSK4
Human PBMCs and T cells; Mouse in vivo models./↗IL-10, IFN-γ and IL-12 by human PBMCs, both directly and on antigen restimulation; ↘allergy in different models (↘Th2 cells, IgE, and eosinophilia)
Mouse/↗IL-12p35 and IL-10 in BM-DCs and oral myeloid DCs; treated DCs ↗IFN-γ and IL-10 by naïve CD4+ T cells; Sublingual administration with antigen in Ova-sensitized mice ↘airway hyperresponsiveness and Ova-specific IL-5 and IL-10 in cervical lymph nodes
Human Mo-DCs and Mouse spl. DCs, in vitro; Mouse, in vivo/↗high IL-10, low IL-6 and IL-12p70 by DCs; In vivo: low costimulatory molecules on splenic DCs or proinflammatory cytokines, induction of specific T cells secreting IL-10 but little Th1 or Th2 cytokines, and unresponsiveness to challenge with the antigen plus adjuvant (IFA)
Mouse/Direct activation of Tregs, with TCR and IL-2 stimulation, induced proliferation and temporary loss of suppressive properties, which are restored after removing the stimulus
Mouse/Induction of specific CTL responses higher than peptide admixed; In vitro cross-presentation of peptides in fusion, but not admixed, and independently of TLR2
HLA-A2kb transgenic Mouse; Human Mo-DCs/Induction of specific CTL responses. Lipopeptide-pulsed human DCs activated antigen-specific IFN-γ production by autologous CD8+ T cells
Mouse/Branched lipopeptide more potent in the primary response; both induced CTLs and conferred long-term protection against Ova-expressing tumor cells
Mouse/↗specific IgA in mucosal secretions and IgG in the serum after oral immunization. Intragastric delivery ↗systemic T cell stimulation and specific CTL activity
Mouse/i.n. immunization recruited DCs to the NALT, ↗antigen uptake, CCR7 and migration to draining lymph node. TLR2-dependent ↗ of specific CD4+ T cell proliferation, salivary IgA, and serum IgG
