Immune system cells Flashcards
(19 cards)
recognises antigens presented by MHC class II and expresses CD4+ major source of IL-2
helper T cells
helper T cells- adaptive or innate immune response?
adaptive
recognises antigens presented by MHC class I and expresses CD8+
cytotoxic T cells
cytotoxic T cells - adaptive or innate immune response?
adaptive
acts as antigen presenting cell
major cell of the humoural immune response
B cells
B cells - adaptive or innate immune response?
adaptive
produce large amount of antibody specific to a particular antigen
differentiated from B cells
plasma cells
Plasma cells - adaptive or innate immune response
adaptive
primary phagocytoic cell in acute inflammation
Multi lobed nucleus
most common WBC
neutrophil
release histamine during IMMUNE response
expresses IgE receptors on cell surface
Bi-lobed nucleus
Basophil
Neutrophil - adaptive or innate response?
innate
basophil - adaptive or innate?
innate
releases histamine during ALLERGIC response
expresses IgE receptors on cell surface
similar function to basophils, but not basophils 😁🤷🏼♂️
mast cell
mast cell - adaptive or innate
innate
defends against protozoan and helminthic infections
bi-lobed nucleus
eosinophil
differentiates into macrophage
kidney shaped nucleus
monocyte
involved in phagocytosis
acts as antigen presenting cell
major source of IL-1
macrophage
induces apoptosis in virally infected and tumour cells
natural killer cell
acts as antigen presenting cell
dendritic cell
