What are the main functions of a macrophage?
Fagocitosis, Inflamación, APC
APC stands for Antigen Presenting Cell
What is the primary function of dendritic cells?
APC
Principales para lingo T
Dendritic cells are key antigen-presenting cells in the immune system.
What functions do neutrophils perform?
Fagocitosis, Inflamación
Neutrophils are essential for the innate immune response.
What is the role of eosinophils?
Exocitosis, Eliminación de helmintos
Eosinophils are particularly important in combating parasitic infections.
What is the main function of basophils?
Inflamación rápida y alergias
Basophils are involved in inflammatory responses and allergic reactions.
What do mast cells primarily contribute to?
Inflamación rápida
Mast cells release histamine and other mediators during inflammation.
What is the function of innate lymphoid cells (ILCs)?
Producen citocinas, Amplifican la respuesta inmunitaria
ILCs play a key role in the innate immune response.
What specific function do NK (Natural Killer) cells have?
Lisis de células infectadas y tumorales
NK cells are crucial for targeting and destroying infected or cancerous cells.
What are the main receptors of macrophages?
Receptores de PAMP, TLR, FcgR, Receptores del complemento
TLR stands for Toll-Like Receptors and are vital for pathogen recognition.
What are the characteristic markers of macrophages?
CD68+
## Footnote
CD68 is a marker of macrophage activation.
Where are macrophages predominantly located?
Tejidos, Abundan en piel, mucosas y órganos linfoides
Macrophages are widely distributed throughout the body.
What is the primary role of TLR in immune cells?
Receptores de PAMP
TLRs help detect pathogens and activate immune responses.
What is the primary function of the receptors found in eosinophils?
Exocitosis, Eliminación de helmintos
Eosinophils use these receptors to target and expel parasites.
What are the key markers for NK cells?
CD56+
CD3-
## Footnote
CD56 is a marker commonly used to identify NK cells.
What is the common location for neutrophils?
Sangre, Van a los tejidos durante la inflamación
Neutrophils circulate in the blood and migrate to sites of infection.
True or False: All immune cells have TCR and BCR.
False
Some immune cells, like ILCs and NK cells, do not express TCR and BCR.
What is the unique characteristic of basophils regarding their response?
Inflamación rápida
Basophils facilitate rapid inflammatory responses.
Fill in the blank: The main receptors for neutrophils include _______.
Receptores de PAMP, TLR, FegR y de complemento
These receptors are crucial for recognizing pathogens.
FcGR, FcER y TLR
Eosinofilos
FCgR y TLR
Basofilo
Receptores de matocitos
FcgR y fceR y TLR
Son abundantes en tejidos
ILC, MASTOCITO, c. Dendriticas (menos en cerebro)
Macrofago
¿Qué son los macrófagos?
Los macrófagos son células que pueden estar presentes en los tejidos y son considerados profesionales en la fagocitosis.
¿Qué son los mastocitos?
Los mastocitos son inflamocitos tisulares que se tiñen con colorantes ácidos, como la cosina.
