Dendritic cells are a type of immune cell found in the immune system of mammals. Their main role is processing antigen materials and delivery of these materials to surfaces of other cells.

What cells originate from monocytes?

Macrophages and dendritic cells originate from monocytes. Monocytes are a type of white blood cell that circulate in the bloodstream and can differentiate into macrophages which are involved in immune responses and tissue repair, or dendritic cells which play a key role in presenting antigens to activate T cells in the immune system.


Phagocytic cells that occupy the epidermis are called?

The epidermis contains phagocytic cells called DENDRITIC CELLS. The slender, fingerlike processes of dendritic cells extend among the surrounding cells, forming an almost continuous network to intercept invaders.


Reticuloendothelial tissue is composed of cells that are what?

Reticuloendothelial tissue is composed of cells that are primarily macrophages and dendritic cells. These cells play a crucial role in the immune system by capturing and processing foreign particles and pathogens.


What cell introduces epitopes to T cells?

Antigen-presenting cells (APCs), primarily dendritic cells, macrophages, and B cells, introduce epitopes to T cells. They process and present peptide fragments of antigens on their surface using major histocompatibility complex (MHC) molecules. This interaction is crucial for T cell activation, allowing them to recognize and respond to specific pathogens or infected cells. Dendritic cells are particularly effective at initiating T cell responses due to their ability to capture and present antigens in lymphoid tissues.


The main antigen-presenting cells in the body are?

The main antigen-presenting cells in the body are dendritic cells, macrophages, and B cells. These cells play a crucial role in initiating and modulating the immune response by capturing, processing, and presenting antigens to T cells.

What is the function of the Lymphatic?

The lymphatic system transports fatty acid, white blood cells, and dendritic cells. It also removes interstitial fluid from the tissues in the human body.


How do dendritic cells activate T cells in the immune response?

Dendritic cells activate T cells in the immune response by presenting antigens to the T cells. This interaction triggers the T cells to become activated and initiate an immune response against the specific antigen.


Which cell is known as antigen presenting cell?

What type of lymphocyte is concentrated in the germinal centers?

3 types: Dendritic cells, B cells and CD4+ T cells.


What are white blood cells found in the epidermis that phagocitize mircrobes?

Where in the lymph node do the T cells first encounter antigens presented by dendritic cells?

deep in the cortex.


Are Macrophages and Dendritic cell the same?

Both macrophages and dendritic cells are formed from the same precursor cell, the monocytes. However, the two cells serve different functions during an infection. Macrophages remain in the area of the infection and phagocytosis (engulf) foreign invaders and dead cells. Dendritic cells leave the infected tissue and travel to local lymph tissue in order to alert the adaptive immune system.


What are the skin macrophages that help activate the immune system?

Epidermal dendritic cells


What is the function langerhans cells?

Langerhans cells are a subset of dendritic cells that reside in the epidermis (Part of the immune system). They have long dendrites (like arms) that capture antigen in the skin, and when they find an antigen, they migrate to lymph nodes and present to T cells allowing the adaptive immune system to respond.
