immunology/hematopoiesis Flashcards
(22 cards)
cytokines
small proteins released by cells that specifically affect cell-to-cell communication; these include colony-stimulating factors, interleukins, and interferons
erythropoietin
hormone secreted by the kidneys that stimulates bone marrow production of red blood cells
colony stimulating factor (CSF)
a cluster pattern derived when hemopoietic stem cells are cultured
interferons
interfere with the ability of viruses in infected cells to replicate and spread to uninfected cells
interleukin
may act only in combination with another factor, may be suppressive rather than stimulatory, or may involve a specific function
immunostimulants
drugs that stimulate immune function to fight infection and disease
autoimmune disorders
conditions associated with an abnormal immune response to self antigens on body tissue, resulting in ongoing inflammation and damage to body tissues
cytotoxic
causing cell death
graft versus host disease (GVHD)
complication of bone marrow or stem cell transplantation where activated T cells in donor bone marrow attack host tissues producing inflammatory changes in the skin, liver, and GI tract; can also occur infrequently with a blood transfusion
monoclonal antibody
immunoglobin therapeutically replicated in laboratory cells to react with a specific cell antigen altering the immune response to that antigen
polyclonal antibody
mixtures of antibodies produced by several clones of B lmphocytes
myelosuppression
bone marrow depression
neutropenia
low neutrophil count
cell cycle
series of intracellular events or occurring from one cell division to the next
mucositis
inflammation of mucous membranes
thrombocytopenia
low platelet count
immunosuppressants
drugs that lower the body’s normal immune response
stomatitis
inflammation of the mucous membrane of the mouth
tumor necrosis factor (TNF)
a proinflammatory cytokine that is produced by white blood cells (monocytes and macrophages)
glucocorticoid
any of a group of corticosteroids that are involved in the metabolism of carbohydrates, proteins, and fats and have anti-inflammatory activity.
leukopenia
a reduction in the number of white cells in the blood, typical of various diseases.
cyctitis
inflammation of the urinary bladder. It is often caused by infection and is usually accompanied by frequent, painful urination.
