Heme/Onco Flashcards
CD 34+
hematopoietic stem cell
membrane contains Cl-/HCO3- antiporter
RBC
don;t produce net ATP during glycolysis
RBC
2,3, BPG in RBC
produced from 1,3 BPG by bisphosphoglycerate mutase using ATP
platelet contents
dense granules (ADP, Ca2+), alpha granules (vWF, fibrinogen)
where is 1/3 of platelets stored
spleen
blood cell differentiation fro highest to lowest
neutrophils, lymphocytes, monocytes, eosinophils, basophils
hypersegmented polys
B12/folate deficiency
high cortisol state and neutrophils
disrupts ability of neutrophils to adhere to wall of damaged tissue releasing them into circulation
frosted glass cytoplasm
monocytes
what activates macrophages
gamma interferon
surfacemarker for macrophages
CD 14
eosinophils produce
histaminase and arylsulfatase
causes of eosinophilia
neoplastic, asthma, allergic, collagen vascular disease, parasites
mediates allergic reaction
basophil
contain heparin, histamine, LTD4
basophil
basophilia
usually seen with CML
can bind Fc portion of IgE
mast cell
involved in type 1 hypersensitivity
mast cell
chromolyn sodium
prevents mast cell degranulation
increased production of gastric acid by parietal cells
systemic mastocytosis
most sensitive cells to radiation
lymphocytes
produces lymphocytosis promoting factor and blocks lymphocytes from leaving blood
Bordetella pertussis
express CD8, recognize MHC I
cytotoxic T cells
