Question Answer
The Inflammatory response: is a cascade of cells that cells that are involved
Cells involved in inflammatory response: Lymphocytes: T-lymphocytes & B-lymphocytes, Antigen
Acquired immunity You were not born with it, & it is not automatic
Antigen exposure stimulates... acquired immunity
Lymphocytes are stimulated by... antigen
Antigen stimulates... Lymphocyte activity, usually protein or parts of proteins
T-lymphocytes cell based immunity
B-lymphocytes Antibody based immunity
T-lymphocytes start... The process of the antigen stimulation of lymphocytes
How are T-cells activated? By antigen receptor match (APC)
Occurs in the lymph-nodes or spleen a. Cytotoxic -activity promoted by cytokines, make holes in virally infected or cancer cells. b. helper-release cytokines promoting clonal expansion of B-cells c. Memory T-cells
Types of inflammatory response: 1. Acute inflammatory response 2. Chronic inflammatory response
When __ inflammatory response is not s not sufficient to deal with a pathogen, __ takes over Acute; Chronic
What cells mediate chronic inflammation? B-cells & T-cells leukocytes/lymphocytes
These white blood cells make up the Adaptive Immune System: B-cells and T-cells
Antigen is the specific structural sequence the receptor can bind to.
Where do antigens come from? from bacteria, not from the body
Clonal expansion copies of the matched T-cell to fight the antigen
How are left over T-cells discarded? They are not, they remain in the body as memory cells. Some even get used up
T/F: T-cells can target a damaged d or broken cell(s) and even destroy them. True
Types of T-cells: 1. Cytotoxic- cell destroyer 2. Helper (t-cells) - help stimulates copies of themselves 3. Memory cells
Cytokinesis - Promote clonal expansion substances released by white blood cells. - differentiate into plasma which release anti bodies
Macrophages present the antigens to T-cells to be destroyed
B-cells
