Epidermal dendritic (langerhans) cells function as a part of what response?
Epidermal dendritic (Langerhans) cells play a crucial role in the immune response, particularly in the skin. They act as antigen-presenting cells, capturing and processing pathogens and foreign substances. Upon activation, they migrate to lymph nodes to activate T cells, contributing to the adaptive immune response. This function is essential for skin immunity and protection against infections.
What is the function of epidermal dendritic cells?
Epidermal dendritic cells, primarily Langerhans cells, are key components of the skin's immune system. They play a crucial role in recognizing and capturing pathogens, such as bacteria and viruses, and then presenting antigens to T cells to initiate an immune response. Additionally, these cells help maintain skin homeostasis and participate in allergic reactions and inflammatory responses. Their strategic location in the epidermis allows them to act as sentinels against environmental threats.
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.
Which epidermal layer has the highest concentration of epidermal dendritic cells and has numerous desmosomes and thick bundles of keratin filaments?
The epidermal layer with the highest concentration of epidermal dendritic cells is the stratum spinosum. This layer is characterized by numerous desmosomes that provide structural integrity and thick bundles of keratin filaments, which contribute to the skin's protective barrier. The dendritic cells in this layer play a crucial role in the immune response by detecting pathogens and activating immune cells.
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.
What are epidermal dendritic cells?
Langerhans 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.
Epidermal dendritic (langerhans) cells function as a part of what response?
Epidermal dendritic (Langerhans) cells play a crucial role in the immune response, particularly in the skin. They act as antigen-presenting cells, capturing and processing pathogens and foreign substances. Upon activation, they migrate to lymph nodes to activate T cells, contributing to the adaptive immune response. This function is essential for skin immunity and protection against infections.
What is the function of Dendritic cells and macrophages in the lymph nodes?
Dendritic cells and macrophages play crucial roles in the immune response within lymph nodes. Dendritic cells act as antigen-presenting cells, capturing and processing antigens from pathogens and then presenting them to T cells to initiate an adaptive immune response. Macrophages help in phagocytosing pathogens and debris, while also presenting antigens to T cells, thereby facilitating the activation and differentiation of these immune cells. Together, they orchestrate the immune response by enhancing communication and coordination between innate and adaptive immune systems.
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?
Dendritic cells,macrophages, B cells

Lymphatic system function?
The lymphatic system has 4 main functions. It transports dendritic cells, white blood cells, and fatty acids. It also removes interstitial fluid from tissues.
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?
I believe they are the myeloid dendritic cells called Langerhans cells.
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.
