What do dendritic cells display?
Functional Cell Biology Dendritic cells (DCs) are professional antigen presenting cells that inform the fight against invasive pathogens while enforcing tolerance to self and harmless environmental antigens. They capture pathogens and receive signals from pathogens that influence the outcome of immune responses.
Are dendritic cells CD11b+?
Dendritic Cells in Nonlymphoid Tissues cDCs represent 1–5% of tissue cells depending on the organ and consist of two major subsets: CD103+CD11b− and CD11b+ cDCs.
Where are the dendritic cells found?
Dendritic cells are found in tissue that has contact with the outside environment such as the over the skin (present as Langerhans cells) and in the linings of the nose, lungs, stomach and intestines. Immature forms are also found in the blood.
What are type 2 dendritic cells?
A subtype of conventional dendritic cells, cDC2, are able to prime CD4+ T cells for antitumor functions and the presence of cDC2 in human cancer samples may serve as a predictive biomarker for survival and response to immune checkpoint blockade.
Which cells are dendritic cells?
What are CD11c+ cells?
11.4. Dendritic cells are CD11c+ cells that link the innate and adaptive immune responses, via recruitment of immune effectors cells such as NK, NKT (natural killer T) cells, and neutrophils.
What are intestinal dendritic cells (DCs)?
Intestinal DCs may be targeted for disease therapy or to improve vaccine responses. Dendritic cells (DCs) are bone marrow-derived antigen presenting cells which comprise two major subsets: conventional (or classical) DCs (cDCs) and plasmacytoid DC (pDC).
What is the function of dendritic cells?
Dendritic cells (DCs) mediate tolerance to food antigens, limit reactivity to the gut microbiota and are required for optimal response to intestinal pathogens. Intestinal DCs are heterogeneous but collectively generate both regulatory and effector T cell responses.
How do bacteria and dendritic cells interact to regulate intestinal immunity?
Modulation of dendritic cells by bacterial products influences these different outcomes and therefore interactions between dendritic cells and bacteria are central to the regulation of intestinal immunity.

Are steady-state intestinal DCS exclusively regulatory in nature?
However, responses induced by steady-state intestinal DCs are not exclusively regulatory in nature; effector T cells with specificity for commensal bacterial can be found in the healthy mucosa and these can be locally controlled to prevent inflammation.
