Q

rheumatoid arthritis is chronic inflammation due to what?

A

autoimmune disease

17
Q

what is the difference between a monocyte and a macrophage?

A

same cell “monocyte” when in blood “macrophage” when in tissue

18
Q

what are different types of macrophages?

A
  • microgila (CNS) - kupuffer cells (liver) - alveolar macrophages (lung) - osteoclasts (bone)
19
Q

what are the roles of an activated macrophage?

A
  • phagocytosis - production of factors that stimulate angiogenesis
20
Q

what is a granuloma?

A
  • collection of activated epithelioid macrophages (pink cytoplasm, indistinct cell membranes, oval nucleus) - Surrounded by mononuclear leucocytes - Caseating or non-caseating - May also contain multinucleate giant cells
21
Q

what cells do you find in connective tissues?

A

mast cell fibroblast macrophage

22
Q

what cells do you find in vessels?

A
  • polymorphonuclear leukocyte - lymphocyte - platelets - monocyte - clotting factors (cytokines complement proteins etc) - eosinophils - basophils
23
Q

what will an early granuloma look like?

A
  • macrophage core - surrounded by lymphocytes (B and T cells)
24
Q

what will a caseous epitheloid granuloma look like?

A
  • caseous necrosis core - surrounded by macrophages - surrounded by lymphocytes (B and T cells) - surrounded by fibroblasts producing collagen
25
Q

what will a non-caseous epitheloid granuloma look like?

A
  • macrophage core - surrounded by lymphocytes (B and T cells) - surrounded by fibroblasts producing collagen
26
Q

what cell is this?

A

eosinphill

dotty cytoplam

multi lobed nuclei

red tomato wearing sunglasses

27
Q

when would you see a eosinophil or mast cell?

A

during an allergic response

28
Q

what cell is this?

A

mast cell

dense, purple

29
Q

what cell is this?

A

lymphocyte

dense large nuclei/takes up whole cell

30
Q

what cell is this?

A

plasma cell

dotty nucleus - chromatin is clumped

nucleus positioned at one end of cell

31
Q

what cell is this?

A

fibroblasts

long cigar shaped

what cell is this?

A

monocyte

bean shaped nuclei
