The mononuclear phagocytes (dendritic cells and macrophages) are closely related immune cells with central roles in anti-infectious defense and maintenance of organ integrity. The canonical function of dendritic cells is the activation of T cells, whereas macrophages remove apoptotic cells and microbes by phagocytosis.Macrophages and dendritic cells are two main types of antigen-presenting cells. They destroy pathogens through phagocytosis and present pathogen-related antigens to the cells in the adaptive immune system. Also, both are involved in the activation of naive B cells. Moreover, both perform their functions inside tissues.During disease, dendritic cells may initiate autoimmune responses and stimulate T cells with resultant macrophage activation inducing significant tissue damage.

What function do both macrophages and dendritic cells perform?
Macrophages and dendritic cells are two main types of antigen-presenting cells. They destroy pathogens through phagocytosis and present pathogen-related antigens to the cells in the adaptive immune system. Also, both are involved in the activation of naive B cells. Moreover, both perform their functions inside tissues.
Can dendritic cells activate macrophages?
During disease, dendritic cells may initiate autoimmune responses and stimulate T cells with resultant macrophage activation inducing significant tissue damage.

What is the role of dendritic cells and macrophages in activating T cells?
Both dendritic cells and macrophages can stimulate naive CD8 T cells in vivo to proliferate, develop effector function, and differentiate into memory cells. J Immunol.
Are macrophages and dendritic cells the same?
Until recently they have been regarded as relatively discrete cell types, with macrophages being a key com- ponent of the innate immune system while dendritic cells interface with the adaptive immune system and modulate immune responses.
How are most dendritic cells related to macrophages quizlet?
How are most dendritic cells related to macrophages? Dendritic cells are also sentinel cells that function as “scouts”. Collect antigens from the tissues and then bring them to lymphocytes that gather in the secondary lymphoid organs.
Are dendritic cells derived from macrophages?
Classifying mouse dendritic cells
We propose that DCs should be classified as a separate lineage of mononuclear phagocytes on the basis of the fact that they arise from adult haematopoietic stem cell (HSC)-derived precursors that are distinct from the precursors of monocytes and macrophages (Fig. 1).
What is macrophages and dendritic cells?
The mononuclear phagocytes (dendritic cells and macrophages) are closely related immune cells with central roles in anti-infectious defense and maintenance of organ integrity. The canonical function of dendritic cells is the activation of T cells, whereas macrophages remove apoptotic cells and microbes by phagocytosis.

Macrophages and dendritic cells: what … – Kidney International
Macrophages and dendritic cells are key players in many renal diseases, such that modulation of their function holds thera- peutic promise.
How are dendritic cells activated?
DCs are activated directly by conserved pathogen molecules and indirectly by inflammatory mediators produced by other cell types that recognise such molecules. In addition, it is likely that DCs are activated by poorly characterised cellular stress molecules and by disturbances in the internal milieu.
How do macrophages activate T cells?
Macrophages interact with T cells in order to bring about T cell activation in target organs, and are themselves activated by inflammatory messenger molecules (cytokines) produced by the T cells. Macrophages produce toxic chemicals, such as nitric oxide, that can kill surrounding cells.
How do dendritic cells interact with T cells?
Dendritic cells (DCs) play a central role in the regulation of the balance between CD8 T cell immunity vs. tolerance to tumor antigens. Cross-priming, a process which DCs activate CD8 T cells by cross-presenting exogenous antigens, plays a critical role in generating anti-tumor CD8 T cell immunity.
How does a macrophage present the antigen to T helper cells?
Macrophages can be stimulated by T cell secretion of interferon. After this activation, macrophages are able to express MHC class II and co-stimulatory molecules, including the B7 complex and can present phagocytosed peptide fragments to helper T cells.
What is the function of dendritic cells?
Dendritic cells (DCs) represent a heterogeneous family of immune cells that link innate and adaptive immunity. The main function of these innate cells is to capture, process, and present antigens to adaptive immune cells and mediate their polarization into effector cells (1).

Images related to the topicAntigen-Presenting Cells (Macrophages, Dendritic Cells and B-Cells)
Do macrophages or dendritic cells present antigens?
Both macrophages and DCs process antigens via the classical endogenous and exogenous pathways and present these on their MHC class I and II molecules, respectively, but they differ in their capacity to cross-present exogenous antigens in MHC class I and to cross-prime CD8+ T cells.
Where are macrophages and dendritic cells found?
These cells are derived from a common DC progenitor and precursors of cDCs (pre-cDCs) form in the bone marrow and disseminate to lymphoid organs (Figure 1). In addition to cDCs derived from common DC progenitors and pre-cDCs, DCs can originate from blood monocytes.
What are macrophages function?
Macrophages are key components of the innate immune system that reside in tissues, where they function as immune sentinels. They are uniquely equipped to sense and respond to tissue invasion by infectious microorganisms and tissue injury through various scavenger, pattern recognition and phagocytic receptors1,2,3,4.
Which cells act in concert with the immune system?
Natural killer (NK) cells
NK cells exhibit an immunomodulatory role in the cell-mediated immune responses due their cytotoxic activity. They are also involved in antimicrobial defense and in the immunological surveillance by controlling tumoral growth and maintaining the immunological homeostasis (Figure 2).
Where do dendritic cells reside?
Dendritic cells are present in those tissues that are in contact with the external environment, such as the skin (where there is a specialized dendritic cell type called the Langerhans cell) and the inner lining of the nose, lungs, stomach and intestines. They can also be found in an immature state in the blood.
What mechanism prevents phagocytosis from engulfing and destroying our cells?
What mechanism prevents phagocytes from engulfing and destroying our own cells? Phagocyte glycoproteins bind CD47.
Which of the following is capable of transforming into macrophages and dendritic cells?
Once recruited to tissues, monocytes are capable of differentiating into macrophages and dendritic cells.
Are monocytes and dendritic cells the same?
In recent years, studies using murine models have clearly demonstrated that monocytes are distinct from conventional dendritic cells (cDCs), which are derived from dendritic cell precursors present in the bone marrow and circulating blood.
Which cells differentiate into macrophages?
Monocytes can differentiate into inflammatory or anti-inflammatory subsets. Upon tissue damage or infection, monocytes are rapidly recruited to the tissue, where they can differentiate into tissue macrophages or dendritic cells.
What is the function of the dendritic cells of the epidermis?
Dendritic cells (DCs) are specialized antigen presenting cells abundant in peripheral tissues such as skin where they function as immune sentinels. Skin DCs migrate to draining lymph node where they interact with naïve T cells to induce immune responses to microorganisms, vaccines, tumours and self-antigens.

Are dendritic cells phagocytosis?
Like macrophages and neutrophils, dendritic cells (DCs) are considered professional phagocytes. Even if the three cell types phagocytose parasites, bacteria, cell debris, or even intact cells very efficiently, the functional outcomes of the phagocytic event are quite different.
What is the function of the dendritic cells of the epidermis quizlet?
What function does epidermal dendritic cells play in the epidermis? Epidermal dendritic cells help activate the immune system within the body. Spiky hemispheres that in conjunction with sensory nerve endings form a sensitive touch receptor.
