Conventional type 1 dendritic cells induce T 1, T 1-like follicular helper T cells and regulatory T cells after antigen boost via DEC205 receptor.

Conventional dendritic cells (cDCs) are specialized in antigen presentation. In the mouse spleen, cDCs are classified in cDC1s and cDC2s, and express DEC205 and DCIR2 endocytic receptors, respectively. Monoclonal antibodies (mAbs) αDEC205 (αDEC) and αDCIR2 have been fused to different antigens to deliver them to cDC1s or cDC2s.

Protective Immunity in Mice Immunized With MSP1-Based Formulations and Challenged With Expressing MSP1.

The lack of continuous cultures has been an obstacle delaying pre-clinical testing of vaccine formulations based on known antigens. In this study, we generated a model to test available formulations based on the MSP1 antigen. The strains ANKA and NK65 were modified to express MSP1 instead of the endogenous MSP1.

CpG Oligodeoxinucleotides and Flagellin Modulate the Immune Response to Antigens Targeted to CD8α and CD8α Conventional Dendritic Cell Subsets.

Dendritic cells (DCs) are antigen-presenting cells essential for the induction of adaptive immune responses. Their unprecedented ability to present antigens to T cells has made them excellent targets for vaccine development. In the last years, a new technology based on antigen delivery directly to different DC subsets through the use of hybrid monoclonal antibodies (mAbs) to DC surface receptors fused to antigens of interest opened new perspectives for the induction of robust immune responses.
